Description/Abstract:
THIS DOCUMENT IS A DELETED VERSION. THIS REPORT, TOGETHER WITH ITS APPENDICES, WAS WRITTEN TO REFLECT THE COMPLETE PICTURE OF THE RADIOLOGICAL SAFETY GROUP, ITS RESPONSIBILITIE S, ORGANIZATION, OPERATIONAL FACILITIES UTILIZED, AND THE DATA OBTAINE D DURING OPERATION TUMBLER-SNAPPER AT THE NEVADA PROVING GROUNDS IN TH E SPRING OF 1952. THE REPORT GIVES IN NARRATIVE FORM A GENERAL DESCRI PTION OF THE FOUR DEPARTMENTS IN THE RAD-SAFE GROUP; CHAPTER 6, "RESUL TS", CONTAINS, IN ADDITION TO THE RESULTS OBTAINED IN THE NORMAL COURS E OF OPERATIONS, A DESCRIPTION OF SEVERAL SPECIAL STUDIES CONDUCTED IN ORDER TO EVALUATE NEW TECHNIQUES, INSTRUMENTS, ETC., AND TO DETERMINE RADIOACTIVE DECAY RATES OF RESIDUAL CONTAMINATION ON THE GROUND. THE CHAPTER ON "CONCLUSIONS AND RECOMMENDATIONS" WAS GIVEN CAREFUL CONSID ERATION BEFORE INCLUSION IN THIS REPORT. NOTATION IS MADE OF RECOMMEN DATIONS STILL AWAITING IMPLEMENTATION AS DIFFERENTIATED FROM THOSE WHI CH WERE ACCOMPLISHED DURING THIS OPERATION (TO JUNE 1952). THE APPEND ICIES, WHICH CONTAIN THE BULK OF THE TECHNICAL DATA, PRESENT IN DETAIL THE RAD-SAFE DATA FOR EACH OF THE EIGHT SHOTS IN THIS TEST SERIES. M ANY OF THE OPERATIONAL DETAILS HAVE BEEN RETAINED SO THAT THE REPORT W ILL BE OF MORE VALUE AS A GUIDE FOR FUTURE RAD-SAFE OPERATIONS. AS A RESULT OF THE RAD-SAFE OPERATIONS DURING TUMBLER-SNAPPER, IT WAS DETER MINED THAT 10 TO 20 KT ATOMIC BOMBS COULD BE DETONATED FROM 300-FOOT T OWERS AT NEVADA PROVING GROUNDS WITHOUT CREATING A RADIOACTIVE HAZARD TO TEST PERSONNEL OR THE POPULATION IN THE VICINITY OF THE TEST SITE, AND WITHOUT DAMAGE TO PLANT OR ANIMAL LIFE. COMPUTATIONS FROM THE DAT A AVAILABLE INDICATE THAT 100 KT BOMBS COULD BE DETONATED AT SCALED HE IGHTS IN THE AIR WITHOUT CREATING A GAMMA RAY HAZARD TO THE POPULATION . THEREFORE, THE LIMITING FACTORS IN THIS CASE WOULD BE BLAST AND THE RMAL RADIATION. **THIS DOCUMENT IS A DELETED VERSION**
