Description/Abstract:
THE DIRECTOR OF THE ATOMIC ENERGY COMMISSION DISCUSSES FINDINGS OF PRO JECT SUNSHINE, A U.S. INVESTIGATION INTO STRATOSPHERIC RADIOSTRONTIUM AND RADIO CESIUM, THE OCCURRENCE OF THESE ISOTOPES IN SOILS, WATER AND THE EARTH'S BIOSPHERE, THE BIOLOGICAL EFFECTS AT CERTAIN LEVELS OF CO NTAMINATION WITH STRONTIUM-90 AND CESIUM-137 AND THE POSSIBLE GENETIC EFFECTS OF LOW GAMMA RAY DOSAGES ASSOCIATED WITH WORLD-WIDE FALLOUT FR OM ATOMIC TESTS. VARIATION IN INDIVIDUAL STRONTIUM-90 BURDEN IS DISCU SSED. FOR THE EVENTUAL STRONTIUM-90 EQUILIBRIUM BURDEN IN HUMAN BONES , 34 PERCENT CAN BE TAKEN AS THE EXPECTED STANDARD DEVIATION FROM THE MEAN. IT IS INDICATED THAT THERE IS NOTHING EXTRAORDINARY IN THE DIST RIBUTION OF RADIOSTRONTIUM IN HUMAN BONE. THE EXPERIMENTAL VALUE FOR THE RATIO BETWEEN THE BODY BURDEN OF YOUNG CHILDREN AND THE AVERAGE CO NTRATION IN TOP SOIL IS ABOUT 50 TO 1 -- A RESULT CLOSER TO THE HIGHER RANGE OF LAB RESULTS THAN TO THE LOWEST RANGE. PRESENT VITAL STATIST ICS SHOW NO OBSERVABLE EFFECT ON THE OCCURRENCE OF BONE CANCER OR LEUK EMIA DUE TO CHANGES IN ALTITUDE. IT IS EXPECTED THAT IN THE U.S. BETW EEN 4 TO 15 SUNSHINE UNITS (1 UNIT 1 MICRO MICROCURIE OF STRONTIUM-90 PER GRAM OF BODY CALCIUM) MIGHT RESULT IF THE PRESENT TYPE OF TESTING CONTINUES FOR THE NEXT 50 YEARS.
