Description/Abstract:
CHAPTER 1-RADIAC SURVEY AND DOSE-ALARM EQUIPMENT EVALUATION-1.1; RADIA C EQUIPMENT OF CURRENT MILITARY INTEREST WAS EVALUATED TO DETERMINE IT S ADEQUACY UNDER REPRESENTATIVE FIELD CONDITIONS. A LIMITED AMOUNT OF INFORMATION WAS OBTAINED ON THE MAINTENANCE AND SPARE PARTS BURDEN OC CASIONED BY FIELD USE OF RADIAC EQUIPMENT. THE FOLLOWING EQUIPMENTS A RE CONSIDERED TO HAVE REACHED DEVELOPMENTAL MATURITY: AN/PDR-T1B, AN/P DR-18, AN/PDR-27 SERIES AND TRACER-LAB SU-13. THE FOLLOWING RADIAC EQ UIPMENTS ARE CONSIDERED TO REQUIRE FURTHER DEVELOPMENT WORK, AND TO EX HIBIT SUFFICIENT PROMISE IN THEIR PRESENT FORM TO JUSTIFY PRIORITY TRE ATMENT IN PROGRAMMING DEVELOPMENT WORK: IM-71/PD(XE-1), IM-70/PD(XE-1 ), NRDL NUMBER 472 RECYCLING IONIZATION CHAMBER DOSIMETER AND ALARM, A ND AN/PDR-37. RADIAC EQUIPMENTS OBSERVED WHICH ARE UNSATISFACTORY IN THEIR CURRENT FORM BUT WHICH MAY, NEVERTHELESS, BE CAPABLE OF DEVELOPM ENT IN A SATISFACTORY FORM ARE: RD-102, AN/PDR-31, AND AN/PDR-32(XN-2) . MODIFICATIONS WERE DEVELOPED WHICH ELIMINATE CURRENT OPERATIONAL AN D MAINTENANCE TROUBLES WITH THE AN/PDR-T1B AND AN/PDR-27. DESIGN AND CONSTRUCTION FAULTS WHICH BECAME MANIFEST IN MAINTENANCE OF THE AN/PDR -18 ARE LISTED. CHAPTER 2-EVALUATION OF DOSIMETERS AND ASSOCIATED EQUIPMENT-2.1; NINE DOSIMETERS, OR ASSOCIATED COMPONENTS, OF CURRENT MILITARY INTEREST WER E TESTED AT THE NEVADA PROVING GROUNDS DURING OPERATION TUMBLER-SNAPPE R. RESULTS INDICATE THAT NONE OF THE DOSIMETERS TESTED ARE ENTIRELY S ATISFACTORY FOR MILITARY USE. THE DT-65/PD WITH ITS ASSOCIATED HOLDER S, PH-650/PD AND PH-656/PD, IS HOWEVER, SATISFACTORY FOR INERIM USE. THE CHARGER PP-3540/PD WAS SUBJECTED TO LIMITED TESTS. FOR THE CONDIT IONS THAT EXISTED AT THE TEST SITE, IT OPERATED SATISFACTORILY. CHAPTER 3-RAPID AERIAL SURVEY-3.1; ON SHOT 7 OF OPERATION SNAPPER A RA PID AERIAL SURVEY OF THE CONTAMINATED AREA WAS CONDUCTED USING AN LC-1 26 LIAISON TYPE AIRCRAFT AND EXISTING PORTABLE MILITARY RADIAC EQUIPME NT. THE RESULTS OBTAINED INDICATE THAT USING A SURVEY METER, SUCH AS AN AN/PDR-T1B OR AN/PDR-18, AND A STOP WATCH IT IS POSSIBLE TO DETERMI NE, WELL WITHIN AN ORDER OF MAGNITUDE, THE CONTAMINATION ON THE GROUND AT A GIVEN SPOT. THIS METHOD SHOWS PROMISE FOR MAKING AN INITIAL POS T-SHOT SURVEY FOR A FIELD COMMANDER, A RADIOLOGICAL SAFETY ORGANIZATIO N, OR CIVIL DEFENSE.
