Measurement of radioactivity in the environment - Air: radon-222 - Part 4: Integrated measurement method for determining average activity concentration using passive sampling and delayed analysis (ISO 11665-4:2012)
Messung der Radioaktivität in der Umwelt - Luft: Radon-222 - Teil 4: Integrierendes Messverfahren zur Bestimmung des Durchschnittwertes der Aktivitätskonzentration mittels passiver Probenahme und zeitversetzter Auswertung (ISO 11665-4:2012)
Overview
Radon is today considered to be the main source of human exposure to natural radiation. The UNSCEAR (2006) report suggests that, at the worldwide level, radon accounts for around 52 % of global average exposure to natural radiation. The radiological impact of isotope 222 (48 %) is far more significant than isotope 220 (4 %), while isotope 219 is considered negligible. Exposure to radon and its decay products varies tremendously from one area to another. It depends firstly on the amount of radon emitted by the soil and, secondly, on the degree of containment and weather conditions in the areas where exposure takes place. This part of the DIN ISO 11665 series exclusively covers radon-222 integrated measurement techniques with passive sampling. It gives indications for determining the average activity concentration of the radon-222 in the air from measurements based on easy-to-use and low-cost passive sampling, and the conditions of use for the measuring device.
