Description/Abstract:
THE SERVICE TEST FOR THE SIGNAL CORPS CONSISTED IN PHOTOGRAHIC MEASURE MENTS MADE IN AN ATTEMPT TO DETECT AN INCREASE IN THE ILLUMINATION OF THE MOON DUE TO AN ATOMIC BOMB EXPLOSION ON THE SURFACE OF THE EARTH. NO INCREASE IN ILLUMINATION WAS OBSERVED AT EITHER STATION BY PHOTOGRA PHIC EQUIPMENT, PHOTOELECTRIC MEANS, OR BY VISUAL OBSERVATIONS. IT IS CONCLUDED THAT SURVEILLANCE OF ATOMIC BOMBS BASED ON THIS METHOD IS NO T FEASIBLE. HOWEVER, IF FUTURE ATOMIC BOMB EXPLOSIONS ARE CONTEMPLATED , IT IS RECOMMENDED THAT CONSIDERATION BE GIVEN TO THE EMPLOYMENT OF A STRONOMICAL TELESCOPES OF LARGE SIZE FOR FURTHER INVESTIGATION OF THIS METHOD OF SURVEILLANCE. ( SECOND ABSTRACT ) THREE ATTEMPTS WERE MADE TO MEASURE THE CHANGE IN THE TOTAL MAGNETIC FIELD OF THE EARTH CAUSED BY THE EXPLOSION OF ATOMIC WEAPONS. MEASUREMENT WERE MADE BY USE OF A MAGNETIC AIRBORNE DETECTOR AT DISTANCES OF 37.5, 31.3, AND 23.8 KILOME TERS; BUT NO POSITIVE RESULTS, I.E. SIGNALS GREATER THAN THE BACKGROUN D OF ABOUT PLUS OR MINUS 1 GAMMA, WERE OBSERVED ON A PRELIMINARY ANALY SIS OF THE DATA.
