Dose Assessment of the Skin Exposures to Six Workers.
The licensee updated the dose assessment on December 5,1979, of the skin exposures received by six workers on August 28, 1979.
The licensee results are summarized below giving the third calendar quarter, 1979, doses to these individuals.
,
10 CFR 20.101(a) sets a limit of 71/2 rems per calendar quarter on dose to the skin of the whole body, and 18 3/4 rems per calendar quarter on dose to the hands and forearms, feet and ankles.

.
.
To avoid any continuation of the overexposure, the six individuals were restricted from radiation work for the remainder of the calendar quarter. There was no lost time off work.
The licensee has reviewed with the radiation protection personnel the corrective actions to preclude any future overexposures.
Personnel were retrained in the selection, use and limitations of survey instruments.
Protective clothing requirements were reviewed.
Planning and preparation for high dose rate jobs were reviewed.
The TMI-2 Radiation Protection Plan is being revised.
NRC is obtaining the services of a consultant to furnish an independent dose assessment of the six individuals.
NRC has reviewed the radiation protection program and directed the above corrective actions.
Onsite inspectors have stepped up the review of survey results and radiation work permits and observe licensee activities on every operating shift.
NRC will continue to review the licensee's performance to ensure that the corrective actions are carried out.
