will have a large portion of the activity removed with the pleural or ascitic fluids, respectively (7).

Urine may contain some radioactivity depending on the time since administration, the radioisotope that was administered, and the route of administration. Within a few days of administration, the urine may contain appreciable radioactivity and, unless directed otherwise, should be drained directly into the sewer system, similar to pleural and ascitic fluid during embalming. It should be noted, however, that activity levels may not be reduced by removal of residual urine. After the first 2 d of the administration of 131I and 89Sr, more than half the activity would normally be excreted through the urine (8) though the patient's medical condition may sometimes delay this process. Draining urine from the bladder of these patients prior to autopsy procedures may reduce radiation exposure. Radioisotopes in the pleural or peritoneal cavities will be much less affected by removal of urine.
