Abstract Woods Hole Oceanographic Institution (WHOI) conducts research involving 125I. When an individual handles or works near unsealed radioiodine, including 125I, above certain activities bioassays are required or may be required. Because of the quantities of 125I being used for a research protocol, a thyroid bioassay and dose assessment system and procedure was developed to comply with this requirement. This procedure includes detector calibration, quality control, determination of recording level, determination of minimum detectable activity, thyroid bioassay (baseline, routine, special, and termination measurements), and intake and dose assessment calculations.
