Bioassay and laboratory survey scheduling based on radioisotope inventory

Bioassay and laboratory survey schedules can be generated using a radioisotope inventory program. This paper discusses the use of laboratory activity, past performance and operational factors for laboratory survey frequency determination, and use of laboratory activity for bioassay scheduling. Mayo Clinic has recently instituted both applications with the use of a computer. Initial results indicate general acceptance of the concept by our radiation workers, an 18% increase in laboratory surveys performed, and a 21% decrease in the total number of bioassays performed annually.
