School Radon Measurement and Exposure Risk Assessment
- Version
- v1
- Updated
- 1 October 2026
- Audience
- Primary and secondary schools in England, including maintained schools and academies; not independent schools.
- Jurisdiction
- england
Activity assessed
Assess potential radon exposure in school premises. Applicability is conditional: measurements should be considered where the school is in a radon-affected area, or where a basement in a non-radon area is occupied for more than an average of one hour per week, equivalent to 50 hours per year. Where measurements indicate that action is required, record and manage the steps needed to limit exposure.
Assess each hazard and its controls against your site before use. Template ratings require local review.
Hazards and controls
The school's radon measurement applicability is not determined, which could result in relevant premises not being assessed for potential radon exposure.
- Existing controls
- No existing site controls or determinations are asserted by this reusable template. Record any existing information about the school's location, premises and basement occupancy when completing the register.
- Proposed controls
- Confirm whether the school is in a radon-affected area. If it is not, identify any basement areas and establish whether each is occupied for more than an average of one hour per week, equivalent to 50 hours per year. Record the basis for the applicability decision and keep the decision under review if premises use changes.
Local assessment and additional controls
Where the conditional measurement criteria apply, measurements are not arranged or are incomplete, leaving potential radon levels in relevant premises undetermined.
- Existing controls
- No completed measurement programme, measuring arrangements or results are asserted by this reusable template. Record any existing measurement arrangements, dates, locations and results separately from proposed controls.
- Proposed controls
- Where the school is in a radon-affected area, or where a basement in a non-radon area is occupied for more than an average of one hour per week, arrange measurements to determine potential radon levels in the relevant premises. Define the premises and locations covered, assign responsibility for arranging the measurements, record the measurement dates and retain the resulting documentation.
Local assessment and additional controls
Radon measurement results are not reviewed, understood or linked to a documented decision, which could delay action needed to limit exposure.
- Existing controls
- No results review, interpretation or decision is asserted by this reusable template. Record the results received and any existing review arrangements when completing the register.
- Proposed controls
- Review the measurement results for the premises covered, record the date and person responsible for the review, document the decision reached, and identify any uncertainty or need for further advice. Where action is required to limit exposure, record the actions, responsible person, target dates and follow-up review.
Local assessment and additional controls
Required action to limit exposure is not identified, implemented or followed up after measurement, potentially allowing continued exposure.
- Existing controls
- No mitigation, exposure-limitation measures or implementation status are asserted by this reusable template. Record any measures already in place and their evidence when completing the register.
- Proposed controls
- Where measurement results indicate that action is required, identify and implement suitable measures to limit exposure, obtain appropriate specialist or regulatory advice where needed, and monitor completion. Consider the requirements of the Ionising Radiations Regulations 2017 where relevant, record the rationale for decisions, and verify that actions have been completed and remain effective.
Local assessment and additional controls
Information about applicability, measurements, results, decisions and follow-up actions is not retained or communicated to relevant school personnel, weakening ongoing management of potential radon exposure.
- Existing controls
- No school-specific records, communication arrangements or review dates are asserted by this reusable template.
- Proposed controls
- Maintain a record of the applicability decision, premises and basement occupancy considered, measurement arrangements, results, decisions, actions, responsibilities and review dates. Make relevant information available to those responsible for school premises and health and safety management, and review the register when occupancy, premises use, measurement information or guidance changes.
