Scope

What is ISO 11665 ‑ 3 about?    ISO 11665 discusses the measurement of radioactivity in the environment. Since radon present in soil can leech into the environment, it can pose a health risk to occupants of buildings where it has entered indoor air. It is important to measure the quantity of radon in this air to determine whether the occupants are safe.   ISO 11665 ‑ 3 is the third part of the multi-series on measurement of radioactivity in the environment that describes spot measurement methods for determining the activity concentration of short-lived radon-222 decay products in the air and for calculating the potential alpha energy concentration.   ISO 11665 ‑ 3 gives indications for performing a spot measurement of the potential alpha energy concentration, after sampling at a given place for several minutes, and the conditions of use for the measuring devices. This measurement method is applicable to air samples with potential alpha energy concentration greater than 5 nJ/m3. BS EN ISO 11665-3:2020 history
