Description/Abstract:
A COMPLETE INVESTIGATION OF THE RADIATION DOSES RECEIVED BY INDIVIDUAL S EXPOSED TO RADIATION IN THE YUGOSLAV ACCIDENT ON 15 OCTOBER, 1958, H AS BEEN COMPLETED, USING MODERN TECHNIQUES OF DOSIMETRY. THE ZERO POWE R REACTOR WAS OPERATED AT LOW POWER LEVELS TO DETERMINE THE RATIO OF G AMMA-RAY TO NEUTRON DOSE AT VARIOUS LOCATIONS NEAR THE REACTOR. THESE MEASUREMENTS WERE MADE WITH SPECIAL COUNTING METHODS, ONE OF WHICH MEA SURED THE NEUTRON DOSE IN THE PRESENCE OF GAMMA-RAYS, AND THE PRESENCE OF NEUTRONS. THE REACTOR WAS OPERATED AT A HIGHER POWER LEVEL FOR A S HORT TIME TO DETERMINE ( A ) THE NEUTRON DOSE BY MEANS OF THRESHOLD DE TECTORS AND ( B ) THE RELATIONSHIP BETWEEN NEUTRON DOSE AND SODIUM-24 ACTIVATION IN MAN-SHAPED PHANTOMS. A COMPUTATIONAL PROGRAM GAVE THEORE TICAL RESULTS FOR THE SAME THREE QUANTITIES, I.E. THE NEUTRON SPECTRUM , THE GAMMA-NEUTRON RATIO, AND SODIUM-24 ACTIVATION. THE RESULTS OF TH EORY AND EXPERIMENT ARE IN GOOD AGREEMENT. FINAL RESULTS FOR THE INDIV IDUAL DOSES ARE SHOWN IN TABLE 7. IN THIS TABLE THE CHARGED PARTICLE D OSE REFERS TO THE FIRST COLLISION DOSE DUE TO RECOILS FROM FAST NEUTRO NS AND INCLUDES THE DOSE DELIVERED BY THE NITROGEN N-P REACTION. THE S ECOND DOSE COLUMN GIVES THE MAXIMUM DOSE OBTAINED FOR THE HYDROGEN CAP TURE GAMMA-RADIATION PRODUCED IN THE PHANTOMS. THE EXTERNAL GAMMA DOSE BASED ON THE MEASURED GAMMA-NEUTRON RATIO IS SHOWN IN THE THIRD COLUM N, AND THE TOTAL DOSES ARE GIVEN IN THE LAST COLUMN. OF THE SEVEN PERS ONS INVESTIGATED, THE HIGHEST DOSE RECEIVED ( INDIVIDUAL V ) WAS 436 R ADS AND THE LOWEST DOSE WAS 207 RADS. THE DOSES PREVIOUSLY ESTIMATED W ERE REPORTED IN REM UNITS, SHOWING FOR INDIVIDUAL V AN ESTIMATED VALUE OF 210 REMS FOR THE NEUTRON DOSE AND 630 REMS FOR THE GAMMA-DOSE, OR
