POCKET NUCLEAR RADIATION MONITORS AND DETECTORS FAQ (Frequently Asked Questions) Will the RadScanner Model 500 detect any remaining radioactivity after medical radiation therapy... ? The medical profession is careful to choose radioactive isotopes that have short half-lives to minimize exposure. Radiation is used for two separate purposes -- therapy... and diagnostic testing. Externally applied radiation therapy often used for cancer therapy uses highly concentrated beams of energy from a nuclear isotope source or a particle beam generator...

between the detector and the point source, the radiation level drops to one fourth. Triple the distance and the field strength is now one ninth. In addition, radiation is adsorbed..., at a certain distance, it becomes unlikely that a "point source" can be distinguished from the background radiation. If directional shielding is used around the detector... stopped by law enforcement officers armed with radiation detectors used to track possible terrorists."-- "High Security Trips Up Some Irradiated Patients, Doctors Say" By AL BAKER...
