A simplified method and a web-based application for the estimation of liquid and solid radioactive waste produced by in vitro nuclear medicine laboratories.

The aim was to develop a web application for the estimation of the radioactivity contained in liquid and solid waste produced by in vitro nuclear medicine laboratories. Median percentages of solid and liquid waste were estimated from successive runs of 44 in vitro kits. This data was fed into a web-based app, which estimates the activity of the waste and provides detailed record keeping. Median liquid/solid waste percentages were 77%/23% for RIA and 95%/5% for IRMA assays. Total waste activities were below regulatory discharge limits.
