Welcome to the Bioassay Project Team Homepage

DOE regulations require routine bioassay monitoring for all workers who have a reasonable potential for intakes of radioactive materials. Prompt and accurate information about potential or actual employee exposure is necessary to accurately assess does equivalent quantities associated with those intakes.

Individuals are monitored for work related intakes through a series of routine and special bioassay measurements. The bioassay program includes both direct (in vivo) and indirect (in vitro) measurements. The C Division Bioassay Project provides radio-analytical services in support of the in vitro (materials removed from the body) portion of the LANL internal dosimetry program, managed by ESH Division.

C Division has committed to providing analytical data of the highest quality within rigid time-frames specified by the customer. Three groups within the division provide integrated/cooperative radio-analytical support for the analysis of plutonium, americium and uranium by alpha-spectroscopy; plutonium by thermal ionization mass spectrometry; and tritium by liquid scintillation. The C Division Bioassay Project team responds to crisis sample requests to provide quick and reliable information to potentially exposed workers -- both a legal and moral obligation. State-of-the art equipment, procedures, and dedicated personnel allow the C Division Bioassay Project team to set the standard for radio-bioassay in the DOE complex.
