Strontium38Sr90has a half-life of 29.1 yr. It is chemically similar to calcium, enters the body through the food chain, and collects in the bones. Consequently,38Sr90is a particularly serious health hazard. How long (in years) will it take for 99.9817% of the38Sr90released in a nuclear reactor accident to disappear?
