strontium unit

strontium unit
(SU)
   a unit of radioactive concentration used to measure the presence of the very dangerous radioisotope strontium 90 in the body or elsewhere. In the body or the environment, strontium atoms tend to replace or become mixed with atoms of calcium. One strontium unit is a concentration of 1 picocurie per gram of calcium (pCi/g Ca). In SI units this is equal to exactly 37 becquerels per kilogram (Bq/kg), that is, 37 atomic disintegrations per kilogram per second.
