Radiation detection nuclear weapons public health

Cesium chloride is derived from cesium-137, a by-product of nuclear fission. In blood irradiators, it is compressed into stainless steel capsules but when released into the atmosphere, cesium chloride can cause radiation sickness, burns, and death. An accidental exposure in Brazil in 1985 killed four people and left 249 others contaminated.
