HS/02/10/477 PUBLIC To: Finance, Resources and Customer Services Policy Board On: 23 April 2026 Report by: Director of Finance and Resources Heading: Corporate Policy on the Management of Radon 1. Summary 1.1 The policy attached to this report ensures that we meet our legal obligations in line with the requirements of the Ionising Radiations Regulations 2017 and provide a safe and supportive living and working environment. 1.2 The Health and Safety at Work Act 1974 and the Management of Health and Safety at Work Regulations 1999 (as amended) places duties on the Council to ensure, so far as is reasonably practicable, the health of our employees and others that could be impacted by acts or omissions. 1.3 Following approval from Members, Officers will follow an engagement plan to work with Housing and other Services to implement the Policy. 2 Recommendations 2.1 Members are asked to approve the Corporate Policy on the Management of Radon. 3. Policy Background. 3.1 This Corporate Policy on the management of radon has been developed in response to a reclassification by the UK Health Security Agency (UKHSA) and the British Geological Survey (BGS). Using an updated statistical modelling approach, these bodies have identified certain areas of Renfrewshire as having a higher potential for radon occurrence due to local ground conditions. This reclassification does not reflect any change in the underlying geology, or the actual levels of radon being emitted.

PUBLIC 1 Introduction This document sets out the Council’s policy for managing risk associated with exposure to radon by employees and persons using Council buildings. Long term exposure to radon may increase the risk of developing lung cancer, especially for smokers. This policy has been developed in line with the general principles outlined in the Council’s Health and Safety Policy and should be used in conjunction with relevant legislation, Health and Safety Executive (HSE)/UK Health Security Agency (UKHSA) guidance, and other recognised procedures relating to the presence of radon in buildings. Where Services occupy premises that are not owned/managed by the Council, they should ensure that the presence of radon is managed by a system comparable to that described in this document 2 Radon properties Radon is a naturally occurring colourless, odourless radioactive gas. It is formed by the radioactive decay of small amounts of uranium and radium that are naturally present in rocks and soils. As a gas, it can seep out through cracks and fissures in the subsoil and will either be released to the atmosphere or can accumulate in the spaces beneath and within buildings. Areas of the UK where UKHSA/British Geological Survey estimate that 1% or more of homes will have a radon level above 200 Becquerels/m³ (Bq/m³) are designated ‘radon affected’ areas. An interactive map showing these areas (as 1km grid squares) is freely available online: (www.ukradon.org/information/ukmaps). The vast majority of Renfrewshire is currently mapped as Class 1 (not radon affected). However, some small areas are shown as radon affected areas – these go up to Class 6, where >30% of properties are estimated to have radon >200 Bq/m3. The Council implemented a programme of testing for radon in Council properties in these areas during 2025 and will continue to monitor those properties on a scheduled basis. 3 Health implications Most of the radon gas breathed in is immediately exhaled and presents little radiological hazard. However, the decay products of radon are radioactive solids. These particles attach to atmospheric dust and water droplets which, when breathed in, can become lodged in the lungs and airways. Some decay products of radon emit harmful radiation called alpha particles, which can cause cellular damage within the lungs. The largest exposure arises in domestic settings (due to the amount of time generally spent at home) but significant exposures can also occur in the workplace. Studies have shown that the risk from radon exposure at 100 Bq/m3
Page 7
PUBLIC over 30 years increases the risk of lung cancer by 5-31%1. The absolute risk is estimated as 25 times greater for smokers than non-smokers2. UKSHA reports that the dose-response relationship appears linear, and that there is no evidence of a ‘safe’ concentration below which there is no risk. 4 Radon Thresholds The workplace action level specified in the Ionising Radiations Regulations 2017 (IRR 2017) is 300 Bq/m³ as an annual average. Where this is exceeded, employers are legally required to notify the Health and Safety Executive (HSE) and take prompt action to restrict employee and public exposure to below the relevant annual dose limit (e.g. an effective dose of 1mSv per year for members of the public)3. The residential action level (set out in the UK National Radon Action Plan, 2018) is 200Bq/m3 as an annual average. A target level of 100 Bq/m3 has also been set as the ideal outcome following remedial action in existing homes and inclusion of protective measures in new homes. The UKHSA recommends that the domestic target level is also applied to schools and buildings with public occupancy exceeding 2000 hours per year. In domestic settings, UKHSA recommends that action to reduce radon exposure is taken where the target level is exceeded (even if below the action level) particularly where there are smokers in the household. The Council will therefore adopt a ‘threshold level’ of 100 Bq/m3 in all our properties (including workplaces and homes) as the point at which we will consider whether remedial action to reduce radon exposure is appropriate. 5 Legal duties The Council recognises its responsibilities as an employer and landlord and aims to reduce exposure to radon to the lowest level that is reasonably practical, and in all cases below the specified action levels, by: • Identifying and testing for radon in Council buildings in radon affected areas. • Having clear procedures in place for the management of radon in affected buildings. • Developing and maintaining records of radon levels in Council buildings. • Providing suitable information, training and advice to employees and other persons likely to be exposed to radon in Council buildings. • Consulting, where necessary, with the Council’s Radiation Protection Adviser (RPA), HSE, UKHSA and specialist consultants. 1https://assets.publishing.service.gov.uk/media/5a7ea84aed915d74e6225a5d/RCE- 2 https://www.who.int/news-room/fact-sheets/detail/radon-and-health 3 Schedule 3 Part 1(5) of The Ionising Radiation Regulations (2017)
Page 8
PUBLIC • Ensuring that any remedial measures put in place to reduce the level of radon in a property are monitored and maintained effectively; and • Reviewing its policy and procedures relating to radon as required. 6 Internal responsibilities General health and safety responsibilities are detailed in the Corporate Health, Safety and Policy. Specific responsibilities in relation to radon are detailed below. The Director of Environment, Housing & Infrastructure must ensure that sufficient resource is made available to: • Provide competent advice on radon risk. • Conduct radon risk assessments and monitoring where required. • Provide competent information, instruction and training to staff, and • Ensure the effective implementation of radon control measures throughout the Council estate. Specific tasks include: • The Environmental Health & Community Safety Manager from Climate, Public Protection & Roads has been appointed for the co-ordination of radon protection within Renfrewshire Council. This officer will be the main liaison between both internal Council Services and external bodies. • Identifying Council buildings that require risk assessment (including testing) using the BGS/UKSHA’s definitive ‘radon potential’ dataset. This licensed dataset from BGS is available to the Council via the Public Sector Geospatial Agreement (PSGA). • Identifying Council workplaces with basements that are occupied for more than 50 hours per year, and ensuring they are monitored whether in radon affected areas or not, in line with UKHSA advice • Ensuring radon risk assessments are completed for Council properties in radon affected areas, and that subsequent recommendations are implemented. Although it is the responsibility of the Director of Environment, Housing and Infrastructure, for the tasks above, effective radon management will require input from other Council services and directorates, and appropriate cross-service staff collaboration/delegation will be expected. The Head of Housing, the Head of Facilities and Property Services and the Head of Climate, Public Protection & Roads will be responsible for ensuring that: • Contract and engineering works are undertaken in accordance with best practice and in a manner that eliminates, reduces or controls identified radon risks.
Page 9
PUBLIC • a database of Renfrewshire Council properties in radon affected areas is maintained (in line with current UKHSA/BGS radon datasets). • all new Council buildings in radon affected areas are designed with the appropriate level of radon protection. • where radon protection is required, a suitable contractor(s) is identified with the appropriate training and expertise to design and carry out remedial works. • a programme of regular, recorded inspections and testing is maintained to demonstrate that radon protection works are undertaken to the required standard and that any control measures in Council buildings are performing satisfactorily, and • radon is included in risk assessments for all Renfrewshire Council controlled workplaces and homes in radon affected areas. Responsible Persons (RP) in premises that have radon shall: • maintain all on-site records pertaining to radon control measures, including risk assessments, test results and inspection reports • ensure that any protection measures provided to control/reduce radon ingress to the building are properly maintained and regularly monitored to ensure effectiveness (e.g. mechanical ventilation using fans). • Ensure that all control measures (including restricted occupation/access) are followed • Communicate with local staff (Note: The procedure for a PPP school may differ from that described above and you should seek clarification from the PPP Projects Officer in the first instance). The Strategic Health and Safety Manager shall be responsible for ensuring that the Health and Safety team monitor the performance of the Council’s radon policy and the effectiveness of its arrangements. 7 Information and training The Council will provide sufficient information and training to ensure that employees in radon affected premises, understand the potential health risks posed by radon in the workplace, and the importance of any management and control measures provided. Information shall be provided by briefing sessions, toolbox talks, articles in staff newsletters and on the Council intranet, and cascading of information within the All employees (e.g. building maintenance personnel, contractors and others) who may work in radon affected buildings shall be given information regarding the safe operation of any engineering controls such as switches, radon membranes/barriers, ventilation systems, sump controls, fans, vents etc) that are in place to reduce radon ingress.

PUBLIC 8 Management of radon 8.1 Risk Assessment Council buildings have been initially assessed to identify the potential for the presence of radon gas. This assessment will be based on the UKHSA/BGS radon probability dataset (25m grid) which will negate the need to order detailed site-specific reports from BGS. Council premises located in radon affected areas (i.e. Class 2 – Class 6 Areas) will, as part of the risk assessment, be monitored for radon gas levels (see ‘Building Radon Checklist’ in Appendix 1). The results of the test will determine what actions will arise. Appendix 2 gives more detail on reassessment and actions. For Council housing, all tenants of houses and ground-floor flats in radon affected areas have been offered a test kit. It is acknowledged that testing in homes will require the tenant’s voluntary participation, and such testing will not be mandatory. The tenants and homeowners have been given information to support this activity. The Head of Housing Services will be responsible for maintaining a list of which properties have been tested, and for ensuring that new tenants in radon affected areas are offered a radon test kit when they move in. 8.2 Radon monitoring The radon level within buildings can be extremely variable and will be dependent on a number of factors including: • the underlying geology; • details of how the building is constructed; and • how the building is heated and ventilated. Monitoring is carried out using passive detectors which are left in place for a period of at least 3 months to reflect typical occupancy. This longer-term monitoring ensures any short-term fluctuations are evened out, and an annual average concentration is then calculated based on this monitoring period. Radon monitoring will be carried out in Council properties at suitable intervals for the level of risk, based upon, for example, published geological information, radon map data and/or the results of previous monitoring in the vicinity. Council premises (without basements) located in non-radon affected areas will not be routinely tested for radon. This position will be reviewed if there is a further change by UKHSA/British Geological Surveys and specific properties may be tested if required following any risk assessment. Council buildings with basement/subterranean areas that are occupied >50 hours/year will be identified and monitored in line with UKHSA guidance, whether they are in a radon affected area or not.
Page 11
PUBLIC In premises where the level of radon is found to be below the threshold level (as specified by the Council) re-testing for radon will be carried out at specified intervals, based on an assessment of the risk (see Appendix 2). Re-tests may also be necessary following any significant changes to a building’s use or performance (for example if the basement begins to be used more frequently or there are energy efficiency upgrades which require below ground construction). Managing the re-test process will be the responsibility of the relevant service. When remedial measures are installed to reduce radon levels, the property will be immediately re-tested to confirm that the measures are functioning correctly and effectively. Regular checks of such measures require to be undertaken by the building’s duty holder (which may be quarterly or annual depending on the type of mitigation measures applied). 8.3 Record Keeping The maintenance of records relating to radon at Council properties will be the responsibility of the Head of Housing, the Head of Facilities and Property Services and the Head of Climate, Public Protection & Roads. It is anticipated that information relating to radon will be included in the Council’s property asset management systems (for example CAMIS, Apex). Records shall include: • Property name, UPRN or Council identifier. • Details of the property’s radon monitoring results. • Records of risk assessments. • The monitoring strategy for the property and any deviations from this. • The design and function of any radon related remedial measures undertaken at the property, along with records of installation and any regular maintenance/inspection, and • Any requirements for controlled or restricted access/occupation. 9 Radon protection measures Any buildings which have been identified as exceeding the Council’s radon ‘threshold level’ may require appropriate controls to safeguard employees, tenants and/or other occupants of the building in accordance with Appendix 2. The Building Research Establishment guidance document BR 211 (‘Guidance on protective measures for new buildings (including supplementary advice for extensions, conversions and refurbishment projects)’) provides guidance on the design of practical, cost-effective radon protection measures. The most suitable mitigation measure (or combination of measures) will be dependent on several factors including radon levels, as well as the building design.
Page 12
PUBLIC 9.1 New buildings It is better to prevent radon from entering a building than to try to remove it once present. All new Council buildings in radon affected areas will be designed and built in accordance with mandatory standard 3.2 set out in Schedule 5 to the Building (Scotland) Regulations 2004 such that “…. there will not be a threat to the health of people in or around the building due to the emission and containment of radon gas”. 9.2 Existing buildings Where monitoring shows the radon level to be above the Council’s adopted ‘threshold level’ of 100 Bq/m3, further risk assessment will be carried out. This will include property-specific considerations, as well as cost/benefit analysis to determine whether further action is warranted. Where remedial measures are considered necessary, they will be designed and implemented as soon as is reasonably practicable. Any such measures will be appropriate to the level of radon detected, the type of building affected and the occupancy rate. Following the introduction of remedial measures, the property will be re-tested as set out in Appendix 2. In exceptional circumstances, it may be necessary to introduce access restrictions on a temporary basis until it is shown that radon levels have been reduced to an acceptable level. Once mitigation measures have been installed, details of the system and any associated test/inspection results should be recorded as set out in Section 8.3. A template checklist for recording inspection visits is included in Appendix 3. 10 Review of the policy The Corporate Health and Safety Team will monitor this policy for its effectiveness. This policy and accompanying documentation contained within will be reviewed and, where necessary, revised on a three-yearly cycle unless an earlier revision is prompted by significant changes in legislation, procedures, best practice or organisational learning. Any changes or amendments to this policy will be done in consultation with The Environmental Health & Community Safety Manager from Climate, Public Protection & Roads and the recognised trade unions.

PUBLIC APPENDIX 2 Generic risk matrix and action protocol Following monitoring and verification of radon levels within a building, the table below sets out the proposed course of action. The proposed action levels apply to all building types (residential, schools and other workplaces – see Note 1) Measured radon level (Bq/m³) Action < 100 • No remedial action required • Re-test at 10-year intervals and/or after any significant refurbishment or change of use 100 - 200 • Take initial practical steps e.g. check existing ventilation and seal obvious entry points (for example, floor cracks, pipe runs) and/or • Carry out building-specific risk assessment (likely to be applicable for occupational settings rather than residential) and where relevant • Re-test (paid for by Council). If re-test result falls within the same range: • Consider and/or implement tailored mitigation strategy within 6 months (see Note 2). This may include engineered methods (see Note 3). • Advise tenants/employees of other ways they can reduce their risk (e.g. stop smoking) if not reasonably achievable to meet target level of 100 Bq/m3 • Re-test at 5-year intervals and/or after any significant refurbishment or change of use. 200 - 1000 • Develop and/or implement tailored mitigation strategy within 3 months (see Note 2) This may include short-term practical steps (e.g. increasing ventilation and sealing entry points) and longer term engineered methods (see Note 3).
Page 17
PUBLIC • For workplaces only, also: - At >300 Bqm-3, report to HSE as required by IRR 2017 (see Note 4) and - Consider restricting access to specific areas, based on site-specific risk assessment. This should take into account factors including radon level, the building design and the pattern and duration of occupation – seek advice from UKHSA / HSE / NHS GG&C as required (see Note 5) • Re-test after remediation (free of charge from UKHSA) • Re-test annually for 2 years and at suitable intervals thereafter and/or after any significant refurbishment or change of use > 1000 > 1000 Residential Workplaces • For residential: - Consult with the UKHSA/NHS Greater Glasgow & Clyde’s Public Health Protection Unit re. short-term intervention/advice to tenants - Develop and/or implement tailored mitigation strategy within 6 weeks (see Note 2) This is likely to include engineered methods (see Note 3). - Re-test once remedial works complete (free of charge from UKHSA) • For workplaces: - Report to HSE as required by IRR 2017 (see Note 4) - Consult with HSE / UKSHA / NHS GG&C and consider any requirement to □ impose immediate restrictions on access to affected area, based upon site specific risk assessment (see Note 5) □ inform and advise employees and any others likely to be exposed
Page 18
PUBLIC • Develop and implement tailored mitigation strategy within 6 weeks (see Note 2). This is likely to include engineered methods (see Note 3). • Re-test once remedial works are complete (free of charge from UKHSA) • Re-test annually for 3 years and at suitable intervals thereafter, and/or after any significant refurbishment or change of use Notes 1) UKHSA recommends the adoption of the residential target (100 Bq/m3) and action levels (200Bq/m3) for schools and non-domestic buildings with public occupancy exceeding 2000 hours per year. 2) When setting timescales for implementing mitigation measures, we may need to allow time for any required statutory approvals (e.g. building warrants) and also consultation/agreement with private owners in mixed-tenure blocks. Mitigation measures will be identified subject to cost-benefit analysis. 3) A tailored mitigation strategy may need to be developed for each individual building. There are practical and relatively inexpensive measures that can be adopted, but the most effective solution in each case will depend upon a number of independent factors including the initial radon level and the characteristics of the building being remediated (e.g. floor type, heating and ventilation). Examples of different types of mitigation, their relative effectiveness and suitability in different situations are discussed in HPA’s 2011 publication “An Analysis of radon remediation methods”. Appendix B of that document describes each method listed below. It is anticipated that advice will need to be sought from specialist consultants to develop detailed designs for specific buildings. Active sump = A sump under a solid floor or impermeable membrane with a fan sucking or blowing from the sump Passive sump = A sump under a solid floor or impermeable membrane with no fan Positive ventilation = A fan, usually in the loft space, blowing into the living space Natural sub-floor ventilation = Clearing airbricks or replacing them with modern vents and/or increasing their number
Page 19
PUBLIC Active sub-floor ventilation = A fan beneath the floor which sucks or blows Passive ventilation = Trickle vents in windows or windows that open on a lockable catch. Best done on lower floors to minimise the ‘stack effect’ and to be kept permanently open. Sealing floors = Sealing cracks and gaps in floors (unsuitable for timber floors). Usually done in combination with other methods Sealing loft hatch = Reduces upward flow of air and thereby reduces the negative pressure in the house. Usually done in combination with other methods. In general, active sumps can be expected to result in up to a 6-fold reduction in radon levels. Other methods such as passive sumps, positive ventilation, natural and active sub-floor ventilation are less effective, offering a typical 2-fold reduction. Passive ventilation and sealing are generally the least effective, offering a less than 2-fold reduction in levels. 4) The Ionising Radiation Regulations 2017 5) Where restrictions on entry are implemented to control occupational exposure, in extreme cases also consider carrying out personal monitoring of any persons required to enter the affected area
Page 20
PUBLIC APPENDIX 3 – Recording maintenance visits and the operational state of radon remedial measures Where mechanical equipment has been installed to reduce the level of radon within a building, a programme of regular checks/inspections should be included in the design specification and implemented as part of the property’s routine maintenance programme Guidance notes: • Mechanical measures to reduce radon gas (e.g. fans fitted to sumps) should operate continuously, and should not be switched off for any reason other than repair or maintenance • Lights attached to fused spur outlets should be illuminated at all times. This indicates that the power is on, NOT that a fan is working so additional checks need to made to confirm that the fan is running. • Air bricks identified as forming part of the ventilation system must always be clear and in good condition • Radon vent stacks should be checked to prevent damage/incorrect use. Look for o Inappropriate connection of wastewater to the vent stack o Removal of rain caps to the vent stack o Vent stack being capped off during re-roofing o Vent stack damage due to vandalism. • Any concerns about the correct operation of the systems should be raised with the relevant service (e.g. Housing, Facilities and Property Services) A template checklist is included below Active Radon Remedial Measures Check Building name Address/UPRN/Description Date Are radon reduction measures in order (/ X) Defect Action taken Owner
