In 2000 cobalt-60 was unwittingly exposed in a scrap metal dump in Thailand. Several of the workers became ill and subsequently died. This was the only recorded incident involving the radioactive substance.
Towards the end there is a uniformed policeman in front of a door. On his right hip is a "clam shell" holster. The holster is cut in half and held together with a spring. It is released by putting the finger into the holster and into the trigger guard and pushing a button; the holster then springs open, releasing the revolver. The danger is that failing to push the button, prevents getting the revolver out. These are no longer used.
Kathie Browne and Sherwood Price, who share a scene in the shoe shop, were married at time of filming.
