F. Personnel Monitoring
8. Bioassays
The necessity of bioassays, as well as the necessity of air monitoring, is determined by the RSO and/or the RRSC based upon the chemical form, the amount of the radioactive material being used, and the intended use. Bioassays may also be required if uptake of radioactive material is suspected (e.g., personal contamination). The following are two types of required bioassays:
Thyroid bioassays will be performed by the RSO between 24 and 72 hours after each iodination procedure. All individuals must have a baseline bioassay conducted before their initial use with radioiodine. The RSO should be contacted to set up a convenient time to do so. The necessity and/or frequency of thyroid bioassays for other procedures will be at the discretion of the RSO.
The RSO may require urine samples from individuals who handle quantities of radionuclides in excess of 20 mCi per experiment. This condition will be addressed in the PH
's permit. Unless otherwise instructed in the permit, these samples should be taken 24 hours after radionuclide use and delivered to the RSO for analysis.|
