Operation Plan CTG 7.3 No. 1-53 weakness and prostration. Mortality produced by an acute exposure of 150 roentgexs will be very low and eventual reccvery of physical fitness may be expected, d. Field commandersshould, therefore, assume that if substantial numbers of their men receive acute radiation exposures eubstantially above 100 roentgens there is a grave risk that their commands will rapidly beceme ineffcctive as fighting units, @. Internal radiation hazards caused by entry of radioactive substances through the mouth, through the lungs or through euts or wounds do not exist after an alr burst. Internal hazards following a contaninating surface explosion may be avoided if ordinary preeavtions are taken, Only under unusual circumstances will there be ipternel hazard from residual contamination. This eliminates the necessity for mas‘ing and consequent reduction of tactical efficiency. 14. The Radiological Safety Officer, Task Group 7.1 will maintain standard type film badge records of radiation exposures for all Task Force personnel. Records will indicate full name, rank or rate, serial _or service number, if applicable, organization, home station or laboratory, date of exposure, and remarks such as limitations on assignment because of exposure. Upon completion of the operation, disposition of these records will be as follows: ae A consolidated list of exposures listing military personnel, and civilian personnel under military control, by full name, rank or rate, serial or service number (if applicable), organization, home station or laboratory and exposure in milliroentgens together with exposed film badges and control film badges will be forwarded to the Chief, AFSwP, b. A consolidated list of personnel and exposures will ke forwarded to the Director, “ivision of Biology and Medicine, AEC. c, Individual records of Navy military and civilian persennel will be forwarded to their unit of assignment for inclusion in the individual's health record (Medical History Sheets and NavMed H-8), For those military personnel exposed to ionizing radiation in excess of that defined by paragraph 3a above, a statement will be included to the effeet that the in- dividual is not to be subjected to ionizing radiation before a specific date, the date to be computed by the Radiological Safety Officer, Task Group 7.1 to allow sufficient time to elapse in order to bring the average radiation dose down to 0.3 roentgens per week, G-I-7
