RESUMO
Operational practices in nuclear power utilities often restrict job assignments for workers with internal contamination due to the difficulty of monitoring for new intakes and strict radioactive material controls. However, restriction of job assignments for an extended period (i.e., months to years) may be too conservative. An industry consensus on guidance in these conditions would be helpful for Radiation Safety Officers (RSOs) to allow long term contaminated workers to have less work restrictions.

Seven individuals were occupationally exposed to airborne radioactive material, which caused an intake of multiple isotopes and an uptake of Co. Committed effective dose equivalents were calculated using ICRP Publication 30 methodology in accordance with US Regulation 10 CFR 20. Doses were in the range of 0.1-2.63 mSv for all individuals. Continued monitoring via whole body counting continues to detect internal contamination of Co from this event at 321 d post intake.
