The highest measured value for radon is 640 Bq/m3

Fjordabladet recently wrote about high radon levels in the Hjelle skule. Avisa now had access to data from different rooms, and the level turned out to be especially high in the basement and in the manager’s office.

The measurement limit is 100 Bq/m3: Radiation protection regulations state that radon reduction measures must be implemented in kindergartens and schools if the radon level exceeds 100 Bq/m3 (measurement limit). Furthermore, the Norwegian Radiation Protection Authority recommends that the radon level always be below the maximum limit of 200 Bq/m3.
