J._Sumpary 1, Using the data from ref. 1, an estimation of several additional doses to the Hiko = Cedar City sheap exposed to fall-out from both Shot 2 and Shot 9 is made. It is contended here that the thyroid dose was higher than ref, 1 indicated, and that total loads of other isotopes in the bone were of even greater importance than the thyroid dose, Some irradiation of the gut appears possible as well as local, moderately strong external doses to mouth and head. a. Total thyroid beta dose from both exposures was estimated at 4530 to 9000 rep (4 isotopes of iodine). b. Maximum conesntraticns in the bone were estimated, at times indleated, of: sr°?

Total beta dose to mucosa of small intestine from fission products as a whole on the order of 10° TED. ad. Local dose around mouth and head as high as 10? rep from cling= ing material: as high as 10% = 10? rep from the ground. e. 2- Total external gamma dose negligible. On the basis of data from thyroid sample counting done in this Laboratory, similar doses to several animals exposed in other areas are calculated. This is done assuming the activity in the thyroid on the date of 4 EE DO*® ARCHIVES
