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.

FACT SHEET: EPA FACTS ABOUT CESIUM-137
Cesium-137 can enter the body when it is inhaled or ingested. After radioactive cesium is ingested, it is distributed fairly uniformly throughout the body's soft tissues. Slightly higher concentrations are found in muscle; slightly lower concentrations are found in bone and fat. Cesium-137 remains in the body for a relatively short time.
