The buyers dismantled the containers, exposing themselves and others to ionizing radiation. Eighteen people, including seven children, were admitted to hospital. Ten of the adults developed acute radiation syndrome. One exposed cobalt-60 source was retrieved, but the source from the other package was still unaccounted for one year later.
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.
A cobalt bomb is a type of "salted bomb": a nuclear weapon designed to produce enhanced amounts of radioactive fallout, intended to contaminate a large area with radioactive material, potentially for the purpose of radiological warfare, mutual assured destruction or as doomsday devices. There is no firm evidence that such a device has ever been ...
Zaire was the world's primary exporter of cobalt and sourced 60% of the global supply. [19] The country also exported 7% of world copper and 33% of industrial diamonds. Many of the mines for these resources were in Shaba, [18] and the copper mines in the area provided 65–75% of the country's overall wealth from imports. [20]
Upon completion of West Cobalt in December 1918, [1] a month after the end of fighting in the First World War, she was handed over to the United States Navy for use in the NOTS.

Around 75 per cent of the world’s cobalt is mined in the DRC -- and the world cannot get enough of it. The rare, silvery metal is an essential component to every lithium-ion rechargeable battery ...
The NRU is a world-renowned research facility, producing about 60% of the world's supply of molybdenum-99, the principle isotope used for nuclear medical diagnosis. Canada also pioneered use of cobalt-60 for medical diagnosis in 1951 and currently the NRU reactor produces the medical-use cobalt-60, while selected CANDU reactors produce ...
