APPENDEX "pH RADTOLOGICAL l. SAFETY GENERAL a. Radiological Safety (RadSafc) of all military and civilian personnel. is & command responsibility, Therefore, the RadSafe organizaLlion for GREENWOUSE con- sisted of units of trained personnel and suitable radiuc coulpment in each of the task groups, In this way the Radsafe units of individual task groups could cope with their probloms as self contained units, ubilising training motnods peculiar to their service requirements, Tho HadSafe unit (Task Unit 3.1.5) of the Seientifie Yask Group (Task Group 3.1) was established to be the primary technical servicing agency te the task force in goncral. For maximum benefit in training, this unit was com posed of representatives from the Army, Navy, Marine Corps, Air Force, U.S. Public Health Servicc, Los Alamos Scientific Laboratory, and 2 representative from the University of Towa. As such, this unit provided all mround monitoring services asso~ elated with experimental projects, laboratory services, omosure rocords, monitoring of sample removal and packaging and protective clothing. b. objectives, The radiclogical safcty phase of Operation GREENHOUSE had three main First, it insured that task force personnel would not be exposed to dan- gercus amounts of radiation. Second, it gorved as a lorge scale training excreise in routine radiological operations, Third, it provided a means for evaluating all available types of radiological, instruments under ficld conditions, ALL three of these objectives were met successfully and several new concepts of the functions of Radsafe in the field have onorged. ¢, ft was learned during this cperatien that presently established pcrsonne dosages are unrcalisticclly low for ficld application to personnel occasionally exposed to rédiation and that many of the available radiclorical survey mebers are toc .sensitive for routine ficld use, Individual dosazes which were permitted on the ep- eration are only O.1 roentgen per day, or 0.7 roentgen por woek. These dosages have been established on the basis of long term exposure for workers in constant cor. tact with radioactive radiation, It is felt that they are far too Low for personne] such as military and civil defense who are only oecasionelly exposed to radiation. Many surveymeters presently available have scales in the iow milli-roenteen rane. Readings obtained on these instruments tend to unduly abara using personnel of limtod experience, wspeclally whon the instruments yo completely off scale at (for ex¥ x . , . . = ~ . ample}; 50 milli~r oentgen per hour, . ‘ ta . r Theso instruments 'pave a distinct place in the . *
