In 1973, 30-year-old Joel Axt was hired by the hospital as the resident physicist ...
According to the 1985 CNSNS report, about four thousand people were exposed to cobalt-60 radiation as a result of the incident. [3] It is estimated that almost 80 percent of people received a dose less than 500 mrem (equivalent to 5 m Sv ); 18 percent, between 0.5 and 25 rems (5–25 mSv); and only two percent (about 80 people) received doses ...
In 1993, director of the Kartontara packing company Vladimir Kaplun was killed by radioactive material (cobalt-60 and/or cesium-137) placed in his chair. He died of radiation sickness after a month of hospitalization. The source of the radiation was found after his death. [12]

A typical cobalt-60 capsule, comprising: (A) An international standard source holder (usually lead), (B) a retaining ring, and (C) a teletherapy "source" composed of (D) two nested stainless steel canisters welded to two (E) stainless steel lids surrounding an (F) internal shield (usually uranium metal or a tungsten alloy) that protects a (G) cylinder of radioactive source material.
Cobalt-60 is used as a radiation source for radiotherapy (specifically, cobalt therapy). Cobalt-60 (60 Co) is a synthetic radioactive isotope of cobalt, with a half-life of 5.27 years, and emits highly penetrating gamma rays. It is commonly used as a radiation source for radiotherapy and equipment sterilization in hospital settings, and also ...
