If radioactive strontium is accidentally ingested or inhaled, the amount absorbed may be calculated with reasonable accuracy from the amount of calcium and strontium excreted in the urine in a single day. The amount retained by the body initially may be calculated from the amount of radiostrontium excreted in the feces in the first few days.
