Terms & Conditions

The Radon Measurement Service reserves the right to amend, or add to, these Terms and Conditions and/or the Schedule of Charges.

Application Procedure

  • Applications for radon in air measurements may be made by completing the application form online, by sending a completed application form by post or fax to the EPA Radon Measurement Service, or by telephoning the EPA (Office of Radiological Protection) Radon Measurement Service.
  • Applications for radon measurements in homes must be paid in advance by cheque, postal order or credit card. The cost of the radon measurement, which includes 2 detectors, is €56.90. Two radon detectors are sufficient to determine the radon concentration in a house. However, if extra detectors are required, there is an additional charge of €28.45 per detector. Prices are subject to annual review. Homes that have had radon remediation work carried out following the discovery of radon concentrations in excess of the national reference level may have a post-remediation radon measurement carried out at no extra charge.
  • Applications from workplaces or schools may be invoiced, provided a Purchase Order number is given at the time of application. Invoices are due for payment within 30 days or the payment period stated on the invoice, if this is greater. The rates for this service depend on the number of detectors being ordered and are available from the EPA Radon Measurement Service. These rates are subject to annual review.
  • All online applications for radon measurements will be acknowledged by electronic means.

Delivery Method and Timing

  • Radon detectors are delivered by post within 28 days of receipt of the application. The customer should notify the Radon Measurement Service if detectors are not delivered within 28 days.

Radon Measurement

  • The EPA is accredited by the Irish National Accreditation Board (INAB) to undertake radon measurements as detailed in INAB Schedule 086T in compliance with the International Standard ISO/IEC 17025:2005 2nd Edition “General requirements for the Competence of Testing and Calibration Laboratories”. 
  • The radon measurement is carried out using CR-39 alpha track diffusion radon gas detectors in accordance with a standard measurement protocol. This measurement protocol is available on the EPA website or may be requested directly from the EPA Office of Radiological Protection.
  • All radon detectors are processed at the EPA Radon Laboratory at 3 Clonskeagh Square, Clonskeagh Road, Dublin 14.

Test Reports

  • A Test Report is issued for each radon measurement. This report includes the contact details of the person requesting the test, the full address of the building tested, the measurement period, the date of issue of the report, the person responsible for issuing the report and the actual measured radon gas concentrations in each room measured. For homes, the average annual seasonally adjusted radon gas concentration is also given. The average annual radon gas concentration is a seasonally adjusted value that takes account of the fact that indoor radon levels tend to be higher in the winter and lower in the summer.
  • In normal circumstances, radon reports are issued within 28 days of receipt of the returned detectors.

Cancellation and Refunds

  • A full refund is available only when the contract is cancelled within seven days of the application date and the radon detectors have not been issued to the customer. Once the radon detectors have been issued, under the EC (Protection of Consumers in respect of contracts made by means of distance communication) Regulations 2001 (Statutory Instrument 207 of 2001), this type of service cannot be cancelled as the transaction is complete.


  • Any complaints regarding the service provided should be submitted to the manager of the Radon Measurement Service at Office of Radiological Protection, EPA 3 Clonskeagh Square, Clonskeagh Road, Dublin 14. All complaints will be investigated promptly.
