Strontium isotopes, emissions from

Radioactive Strontium. If a person has been exposed to radioactive strontium, special tests can be used to measure radioactive strontium in blood, feces, or urine. These tests are most useful when done soon after exposure, since radioactive strontium is quickly incorporated into bone and its release from bone occurs in very small amounts over a period of years. Radioactive strontium can be measured by its mass (in grams) or by its radiation emissions. These emissions, which differ for the various isotopes of strontium, are used to tell the amount of radioactive strontium (in Curies or Bequerels) and the radiation dose in gives to your body (in Sieverts or rem). In a procedure that is similar to being x-rayed, specialized equipment can measure radioactive strontium that has attached to bone.
