Atmospheric radioactivity detector comprises a container that holds a sample of atmospheric air, and has its inner wall lined with a scintillating layer. The scintillating layer, following excitation by particles emitted by radioactive substances, emits photons that are visible through a window in the container, and can be counted. Atmospheric radioactivity detector comprises a container (1) that holds a sample of atmospheric air being tested, and has its peripheral inner wall (5) lined with a scintillating layer (6) on a strip of material (4) that is inserted through the container's opening and fits elastically against its inner surface. The scintillating layer, following excitation by particles emitted by radioactive substances, emits photons that are visible through a window (7) in the container and can be counted. The container has a coupling (3) for attaching it to a filling and emptying system. |
