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

95.99 Withdrawal of Standard Jan 6, 2020

General information

Current stage: 95.99 Effective date: Jan 6, 2020

Originator: ISO

Owner: ISO/TC 85/SC 2

Type: International Standard

Scope

ISO 11665-4:2012 describes 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 sensors.
ISO 11665-4:2012 covers samples taken without interruption over periods varying from a few days to one year.
