TEVISO - Model PB40 -Sensor Tester

The purpose of the PB40 Sensor Tester is to test the functionality of nuclear radiation sensors. It is also suitable for physics classroom experiments without any risk of damage to health. The PB40 contains a small amount of pitchblende (uraninite), embedded in a plastic disk. Pitchblende (uraninite) is a radioactive, uranium-rich mineral and ore with a chemical composition that is largely UO2.
