Description/Abstract:
A HANFORD SLUG WAS DISSOLVED IN NITRIC ACID AND PUMPED INTO SARAN PIPE S DISTRIBUTED INSIDE 100 TONS OF H.E. ABOUT 330 GAMMA CURIES AND 900 B ETA CURIES OF FISSION PRODUCTS WERE THUS DISTRIBUTED IN THE PILE. THE EXPLOSION CREATED A CRATER 36 FEET IN DAMETER AND 4 FEET DEEP FROM A HEIGHT OF 30 FEET ABOVE THE GROUND. THE RADIOACTIVITY OF SAMPLES OF DI RT TAKEN AT VARIOUS DISTANCES FROM THE CENTER OF THE CRATER WAS COMPAR ED WITH THAT OF AN ALIQUOT OF THE ORIGINAL SOLUTION AND IT WAS FOUND T HAT THE FRACTION OF RADIOACTIVE MATERIAL DEPOSITED IN THE GROUND WAS 1 .5 PERCENT UP TO 150 FEET 2.6 PERCENT UP TO 400 FEET WITH A PROBABLE E RROR OF A FACTOR OF 2. THE NUMBER OF MILLIROENTGENS PER HOUR OF RADIAT ION FOUND DIRECTLY AFTER THE SHOT AT A HEIGHT OF 1 FEET ABOVE THE GROU ND COULD BE REPRESENTED BY THE EXPRESSION 12.6(1R/170 FT) UP TO R = 15 0 FEET.
