Descripción de Smoke detector affect on SIRAD sensor.wmv:
You do not have to x-ray the SIRAD sensor film to see results. Common smoke detector foils will visibly radiate the sensor as shown here. The film is calibrated for gamma exposure and the smoke detectors emit alph radiation. Normally the plastic film on the sensor will protect it from detecting alpha which cannot go through your skin. That plastic film has been removed. The sensor is thus "tricked" here into registering gamma instead of relatively harmless alpha. Do not touch the smoke detetor foils with your fingers, use gloves when handling to avoid exposure
