PSD-79-243 July 13, 1979 Continued The IE/THI resident inspection office is doing additional dose assessments beyond the period of the IE investigation. In this connection, calculations indicate that individual B cay also have received an exposure of between 4 and 19 Rem to the sane area of skin of his head during the second calendar quarter of 1979.
The exposure resulted from skin contamination which was deposited during the early part of the accident and was not removed for a period of time.
The licensee restricted individual B from further occupational exposure during the second quarter of 1979.
The Comnanwealth of Pennsylvania has been informed of the exposures.
