Description/Abstract:
SELECTED METALLIC AND NON-METALLIC SURFACES WERE EXPOSED TO THE EFFECT S OF AN ATOMIC EXPLOSION. A REPORT IS MADE OF ALPHA AND BETA-GAMMA CON TAMINATION. ALSO INCLUDED ARE THE RESULTS OF A MICROSCOPIC AND VISUAL EXAMINATION OF THE SURFACES. A REPORT OF THERMAL STUDIES OF THESE MATE RIALS WILL BE FORTHCOMING AT A FUTURE DATE. ABSTRACT II: THE RESULTS OF PHYSICAL OBSERVATIONS MADE BY THE ASSAY GR OUP ON SEVERAL SERIES OF SAMPLES SUBMITTED BY LT. VIEARS ARE PRESENTED . INCLUDED ARE MEASUREMENTS OF ALPHA AND BETA-GAMMA CONTAMINATION, AND REPORTS OF THE MICROSCOPIC AND VISUAL EXAMINATION OF APPROXIMATELY TW O HUNDRED AND FIFTY SAMPLES. THE INFORMATION IS ARRANGED SYSTEMATICALL Y. A COMPLETE STUDY OF THE MATERIALS IS CONTEMPLATED FOR A LATER DATE. ABSTRACT III: THERMAL RADIATION PAPERS WHICH HAD BEEN SUPPLIED BY THE BRITISH MINISTRY OF SUPPLY WERE EXPOSED AT VARIOUS DISTANCES IN TESTS X-RAY, YOKE, AND ZEBRA. WITH ONE EXCEPTION ALL SAMPLES WERE COMPLETEL Y BURNED IN TEST X-RAY, AND THIS ONE SAMPLE AT ABOUT 3500 YARDS CORRES PONDED TO RADIATION CONDITIONS PRODUCING PAIN ON THE EXPOSED SKIN OF H UMAN BEINGS. IN TEST YOKE, A WIDER RANGE OF EXPOSURES WAS OBTAINED AND THESE INDICATED SIMILAR EFFECTS AT APPROXIMATELY 1000 YARDS GREATER D ISTANCE FROM THE POINT OF DETONATION. COMPARISON OF THE ENERGY RELEASE D IN TESTS X-RAY AND YOKE INDICATED THAT THE TOTAL THERMAL ENERGY WAS APPROXIMATELY TWICE AS GREAT IN TEST YOKE AS IN TEST X-RAY. ABSTRACT IV: THIS IS A PRELIMINARY REPORT ON THE WORK, SINCE THE ANALY SIS OF AVAILABLE DATA IS NOT COMPLETE. A PRELIMINARY VALUE OF 4000 TON S TNT EQUIVALENT FOR THE AVERAGE OF X-RAY AND YOKE TOTAL ENERGY RADIAT ED WAS OBTAINED. THIS NUMBER MAY BE IN ERROR BY 50 PERCENT. THE EFFECT IVE DIAMETER OF THE BALL OF FIRE WAS ABOUT 200 YARDS. MOST THERMAL EFF ECTS TAKE PLACE WITHIN TWO SECONDS OF THE DETONATION. THERE IS A PROBA BILITY THAT THE INFRA-RED PREDOMINATES. THE TOTAL ENERGY SEEMS TO DECR EASE WITH DISTANCE ACCORDING TH THE LAW E = ( E ( ORIGINAL ) ) X 2.72 EXP ( -0.9R ).
