The Radiation Sensor Tester is a coin-shape tool for quickly testing functionality of nuclear radiation sensors. The PB40 tester contains a small amount of pitchblende (uraninite), embedded in a plastic disk which is suitable for physics classroom experiments without any risk of damage to health.
The Radiation Sensor Tester is used with the Radiation Click Board™.
Thanks to the hermetical sealing and due to the small amount of radioactive material the PB40 Sensor Tester can be handled without any risk of damage to health. The Radiation Sensor Tester is not suitable for calibration of nuclear radiation sensors.
