• CALCULATION OF DOSE TO A THYROID ,, WY 2 71981 > h-CONTAINING 1 MICROCURIE OF I-131 b cen er ne ta.

PER GRAM OF TISSUE T,y,' '* * /

O ca On May 14, 1981, the Board issued a Memorandum and Order giving notice of its intent to take official notice of a calculation. performed by Dr. Jordan. The proposed calculation has been bound into the record (following Tr. 21,304) and served on the parties, and the Board requested comments on the calculation by May 26, 1981.

Licensee has reviewed the calculation, believes it makes proper use of an accepted calculational technique, and requests the Board to take official notice of the calculation.

Licensee notes that the literature contains a range of values for the average energy of I-131 per disinte:; ration. ICRP (1959)b/

indicates a value of .23 MeV/ dis. Cember (1969) 2/ calculates a value 1/ ICRP Publication 2, Recommendations of the International Commission on Radiological Protection (1959); published by Pergamon Press.

G~

of .187 MeV/ dis, while HEW - (1970) 3_,' lists a value of .180 MeV/ dis. Using these latter figures, the calculated dose to the thyroid would be between 1650 and 1716 rads. Regardless of whether the dose is around 2100 rads or 1700 rads, Licensee

'aelieves the calculation shows Dr. Molholt's value of 2 rads to be in error by about three orders of magnitude.
