An Investigation of the Simulated Twenty-Four Hour Protocol for Uranium in Urine by Kinetic Phosphorescence Analysis


Abstract

Bioassays are the primary means of detecting the nature and quantity of internally-deposited radionuclides in exposed workers. The National Council on Radiation Protection and Measurements (NCRP), in its guidance document on bioassay procedures, defines bioassay as, the determination of the kind, quantity, location, and/or retention of radionuclides in the body by direct (in vivo) or by in vitro analysis of material excreted or removed from the body. This definition is widely accepted by the nuclear industry.

The principal bioassay method used for internal deposition of uranium is in vitro analysis of urine. It internal deposition of uranium occurs, urinalyis is used to detect and quantify the dosimetric consequences to workers. The NCRP states that, Analysis...for materials such as uranium excreted in the urine may provide a useful assessment of the existing systemic burden.
