set Annes APPESOEL NTO TC 7.6 OP PLAIN 1 - 48 RADIOLOGICAL RECORDS I. OVER DXPOSURZ The Task Force has set the linit of cvor exposure at 3R for authorized individuals and porticular jobs only. Tals pancr constitutes an tntorpretation of the moaning sani intent of Annex J to F.0. #1. It must bo assumed for this eperation that the maxinun pernissible dose of .1R per day has no £1] effects on the huncn ofther irnodiately or in the future. On this basis over oxpesure fs not received until elR por day hes been exceeded. In calculating the degree of exposure it can then bo assumed that tho first .1R received is nornelL ond net over exnosure. Txanple: an individual receive es eLR per day for four diys - his over exposure is 0, If on the fitth day he receives 2.°R, Ais ovor oxnosure is 2.3R. If on the sixth day ho reccivos .8R, his over oxposure for that day {5 ,7R and should ba added to the fifth day's ovor exposure for s total of 3R. That being the proscrited Linit tho individual is reported over cxposod and withdrawn Cran radiation activity for thirty days based on a recovery factor of ,R por day. If, however, on tho sixth day he had roceived ecR, his over exposure would vo .IR whieh added to the fifth day's reading of 2.3R would bo 2.4R total over exposure, If he roceived no radiation oxposure for the next five days his total ovor eoxpesure would drep to 1,9R on the basis of the ree covery factor of .LR por dav, The over exposure total would de¢erease cach day ty .1R if no ratiation was received, If, however, he reectved IR each day the total of over exposure would remin 2.4R until the day of no exposure or less than elR. He will recover cach dsy .IR or the fractional difference between eR and the anount recaived. This over exposure total will be kopt on a Radiation Dxposuro Record, Id, MEDICAL PLA CF TIE RAD All individuals whe may bo exposed to radiation during the operation of Task Feree 7 will be oxamined physically mrtor to departure fron the continental Llinits of the United States, Nis examination will cansist ef a completo physical examina} tien cenpirable to the annual examination roquired of military petsonnel and will include a chest X-ray, complete pross and weroscepic urinalysis, and a complete blood count to ineluda a differontial white blood count. If a physical cxamination conprrablo to the above has been taken within the porfod 15 July 1947 amt L Jamuuiry 1938, it nood not be repoated excopt for the chest X-ray, urinalysis, and complatea blood count, Tho fact that the individual was found physically qualified during that pertod for general service afloat or overseas must be certificd by that individual. ail physteal exaninations will bo ovaluated ty the Radgleclogieal Rocords Unit and a dew cisfon rendered as to tho individual's physteal qualifieations for work with radioactive material. All civilians or military personnel Cound not cualiffied for duty afloat or overseas by military stindards or for work with radioactive_matertal will be disqualifiod, Watvers ond oxemptions to the abeve rule «tll be nade by the Task Force Commander. The standanis te bo fole lowed in the evaluation of the bloal counts will bo fer the red bloed count and hacnoglobin, these normally accepted by the medical profession. aeRST “le anney ASSIFLED
