Palo Verde request information on how other stations handle individuals undergoing radioactive seed implant therapy treatments.
1) From a work standpoint, do you place any restrictions on individuals with radioactive seed implants, do you remove an individual's TLD (dose of record device) while the seeds are implanted or through their period of effectiveness? 2) If the individual has measurable external dose rates do you monitor them for potential impact on other station personnel? 3) Do you restrict their work area locations or proximity to other personnel? 4) Do you allow these individuals to enter the RCA and or the Radiological Restricted Area while the seeds are implanted? 5) Do you make any other exceptions or accommodations during their period of treatment? 6) If an individual has a hard to detect radionuclide such as Cs-131, do you monitor or control their activities? * For these isotopes, do you calculate a restriction or monitoring period based on effective half-life? ********************************************************************** Seth J.
