Measurements of gamma-radiation in the environment

Updated 2011-01-24

Measurements of gamma-radiation in the environment (from ground to cosmos). Radioactivity in Intensive Net is measured on the soil surface at 32 sites in Sweden (16 in northern Sweden). The measurements are continuous and sound the alarm if radioactivity increases. Measured is the dose rate of gamma radiation. Radioactivity in Extensive Net is concerned all municipalities in Sweden which has got one instrument for gamma radiation measurement and each county board has got two. Every seventh month they measure radioactivity at two to four predefined spots as reference measurement. Radioactivity in Air is conducted at five stations with air filter sampling and analysis of radioactivity maintained by Swedish Defence Research Agency (FOI). Out of these stations Umeå and Kiruna are located in northern Sweden.

This is a National Implementation Plan (NIP) project
Comments and additional information:

A monitoring programme has concerning radiation issues which have existed since the late 1950's. Monitoring is currently performed continuously on radioactive substances in outdoor air and of ambient gamma dose rates outdoors. Regular measurements every year are performed on radioactive substances in currently sub-programmes including radionuclide in the air particles, radioactive substances in surface and drinking water, sediments of sea and biota. The local environmental monitoring including activities related to nuclear safety as well as data mapping in soil and crops. The programme considers both naturally and artificially occurring radioactive substances, with an emphasis on the latter.
