Description/Abstract:
THE OBJECTIVE OF THIS PROJECT WAS TO EVALUATE UNDER OPERATIONAL CONDIT IONS IN A CONTAMINATED AREA: (1) NEW AND UNTESTED RADIAC INSTRUMENTS, AS WELL AS OLDER TYPES WHICH HAD NOT BEEN FULLY EVALUATED; AND (2) DOS IMETERS, INCLUDING THE NEW ARMY CHEMICAL CORPS CHEMICAL DOSIMETER. DO SIMETERS WERE EVALUATED IN BOTH THE INITIAL- AND THE RESIDUAL- RADIATI ON FIELDS ENCOUNTERED IN NUCLEAR DETONATIONS. NATIONAL BUREAU OF STAN DARDS-TYPE PHOTOGRAPHIC DOSIMETERS WERE USED AS COMPARISON STANDARDS F OR THE INITIAL-RADIATION TESTS, WHILE VICTOREEN R-METERS WERE USED AS COMPARISON STANDARDS FOR THE RESIDUAL-FIELD TESTS. THE RATE METERS WE RE EVALUATED IN RESIDUAL FIELDS BY COMPARISON TO THE STANDARD RATE MET ERS, RADIAC SET AN/PDR-39 AND RADIAC TRAINING SET AN/PDR-T1-B. PERSON NEL OF RADIOLOGICAL SAFETY UNITS AT THE TEST SITE OBTAINED THE DATA US ED FOR THIS EVALUATION. THE RADIOLOGICAL CALCULATOR WAS EVALUATED BY DATA OBTAINED FROM ACTUAL MEASUREMENTS AND BY COMPARISON WITH ISO-INTE NSITY MAPS PREPARED BY THE RADIOLOGICAL SAFETY GROUP AT THE TEST SITE. BOTH THE CHEMICAL DOSIMETER, E1R3, AND THE POLAROID SELF-DEVELOPING FILM DOSIMETER, DT-65, LACK PRECISION AND STABILITY TO SUCH AND EXTENT THAT THEY ARE NOT SUITABLE FOR FIELD USE. THE IM-93 DOSIMETER, HOWEV ER, WAS FOUND TO BE A REASONABLY PRECISE AND ACCURATE INSTRUMENT. RAD IACMETER IM-108 ( )/PD WORKED WELL IN THE FIELD AND GAVE VERY SATISFAC TORY DATA. THE L-SHAPED MODEL (XE-2) IS PREFERRED. THE RADIOLOGICAL CALCULATOR DID NOT PERFORM SATISFACTORILY. THE IM-93 IS THE DOSIMETER THAT MOST NEARLY MEETS DESIRED MILITARY CHARACTERISTICS, AND SHOULD B E ADOPTED WITH A SUITABLE RADIAC DETECTOR CHARGER AS THE STANDARD INST RUMENT FOR MILITARY USE. THE OTHER TWO TYPES OF DOSIMETERS TESTED WER E FOUND TO BE, AT BEST, INTERIM SYSTEMS, AND ARE NOT SUITABLE FOR MILI TARY USE. RADIACMETER IM-108 ( )/PD WAS FOUND TO BE THE ACCEPTABLE RA TE METER, AND SHOULD BE ADOPTED AS STANDARD. THE RADIOLOGICAL CALCULA TOR WILL REQUIRE MORE RESEARCH BEFORE IT CAN BECOME OF USE FOR MILITAR Y APPLICATION.
