Field commanders should, therefore, assume that if substantial nuzbcr of their men receive acute radietion exposures substantially above 100 roentgens there is a grave risk thet their comands will repidly becone ineffective as fighting units, e. Internal radiation hazards caused by entry of radioactive substances through the mouth, through the lungs or through cuts or wounds do not exist after an air burst, Internal hazards following a contarinating surface explosion may be avoided if ordinary precautions are taken, Only uncer unusual circumstances will thcre be internal hezard from residucl contamination, This eliminates the necessity for mesking and consequent reduction of tactical efficiency, 17. The Radiological Safety Officer, Task Group 7,1 will maintain standard type film badge records of radietion exposures for all Task Force persormnel.
