OFF iA tie, ie on ¥ a 4 Wide. ~3- re t ICh. reference lists spleen rather than whole body as the critical creiin. Gustafson probably used whole body so that the doses would be additiv:. toe splean, the following is obtained: AEC Manual Chapter 0524 which treats. the case for the critical organ gives an uncontrolled area MPC for (for individuals). & x 107 3 uCi/ml. ?Fe for water of 8 x 107 The value for the general public would be yCi/mL Assuming an intake on a per day basis we have: 8 x Lom} uci/ml x 1,200 M/s, = +3 nCi/day 3 ny 3x 10° pCi/day Thus, even for the spleen, the dietary value of 59,500 pci/day in Table VI' is only about 1/5 of the MPC. Meg dose (adults) At eqrt librium the initial body burden would be: By = 2,290 pCi/day x 1.44 x 100 days x 1 = 330 nCi Initial dose rate would be: Dose = = “330 uCi x 0.17 - 1 pCi 5 rad/yr Dose = Initial dose rate 5 yr ~ S—— 693/27 |2 -e ~ Ht *] e “34 7 ~~» x 5 = .23 rad This is about one half of the Table VII’ five year dose for OFFIC.
