For how long should measurement reports be kept, according to regulatory recommendations?

Regulatory recommendations typically suggest that measurement reports for radon levels should be retained for a period of six years. This timeframe allows for sufficient record-keeping to address any potential follow-up actions or concerns regarding radon levels in residential or commercial properties. Keeping reports for six years ensures that relevant data is accessible if questions arise about previous measurements or if subsequent testing is necessary.

This duration aligns with guidelines from reputable organizations and authorities involved in radon testing and mitigation. Such practices are vital for maintaining compliance and ensuring homeowners or building occupants are informed about their radon exposure history.

In some cases, while different organizations may advocate for varying retention periods, six years is a commonly accepted standard, making it a reliable benchmark for professionals in the field.
