Searching for Hotspots in an old Basement. Radioactivity is found in many Buildings as a the Product of many natural Building materials. Granite containing Rocks and other natural building materials measurably increase the natural Radiation exposure. However, this change is so minimal that it makes no difference to people's lives. Nevertheless it is possible to measure and detect even such small changes with a sensitive measuring device like the LB 1210B. In this very old Building there were isolated hotspots that deviated from the normal background. Throughout the building the background was around 20 IPS outside this value was between 3 and 6 IPS. In some rooms, the value rose to as high as 50 IPS. #radiation #radon #nuclear #detector #physics - @_someone_ir_07
