Profect 2,6b - RADIOCHEMICAL ANALYSIS OF SURFACE — CONTAMINATION eeeee — . Project Officer ~ R. C. Tompkins Objectives . | ” The objectives of this work were to study the distripution of certain nuclides within fall-out particles and to determine some of tne differences in radiochemical properties between Liquid and solid fall-out. me pone Instrumentation ney « Total fall-out collectors were set up on Enyu, Rukoji, NOT Tene: oon w wen mae + aymyemoEmeSeSeE “; arriizan, end Yokororyuru Islands. On account of a failure in the tining circuit, the collector on Bokororyuru opereted before the shot. The collector on Enyu did not operate properly. Col- lectors on Rukoji and Arriikan operated properly. Results Since the yield : ewe ee AETETERy tne semples recovered were too small to size~grade. Comparisons of the aqueous and solid pheses were made, however, ®S shown in Table 2.6b-1.
