Can scrap metal recyclers find the sources with a radiation detector and just collect them?
Scrap yards and disposal sites attempt to detect orphan sources and other contaminated metals by screening incoming materials with sensitive radiation detectors before they can enter the processing stream and cause contamination. Unfortunately, the protective housings that make the sources safe, also make detection extremely difficult. Further, if the source is buried in a load of steel, the steel acts as further shielding, making detection difficult by today’s radiation detection devices. Consequently, there is always a potential for sources to become mixed with and contaminate scrap metal. EPA is following closely research into improved detection capabilities that can help scrap recyclers detect sources before they cause harm.
