What is the minimum length of time that Licensed Radon Professionals are required to keep testing records?

Licensed Radon Professionals are required to maintain testing records for a minimum period of 5 years to ensure that there is a comprehensive audit trail for all radon measurements conducted. This duration allows sufficient time for reviewing past measurements in case of any disputes or follow-up testing needs. Keeping records for this length of time helps in monitoring trends and responding effectively to client inquiries about past radon levels in their properties.

This requirement aligns with practices aimed at safeguarding public health and ensuring regulatory compliance, which is vital in the management and mitigation of radon exposure. The five-year timeframe strikes a balance between practicality and the necessity for adequate documentation in the field of radon measurement and mitigation.
