Air filter stations – a national network for monitoring radioactivity in the environment

Updated 2016-05-02

The Norwegian Radiation Protection Authority is responsible for a network of 5 air filter stations. These collect air samples through high density filters which are analyzed weekly by gamma spectroscopy. The network was established in the early 80s and is continuously updated. The purpose of the network is to assess the levels and composition of emissions from incidents and accidents. In addition, with the help of meteorological data, possible sources of release may be identified.

This is not a National Implementation Plan (NIP) project
