Project 2.6b - RADIOCHEMICAL ANALYSIS OF SURFACE CONTAMINATION Project Officer ~ R. C. Tompkins Objectives | The objectives of this work were to study the distribution of certain nuclides within fall-out particles and to cetermine some of tne differences in radiochemical properties ee pe re between liquid 2nd solid fall-out. Instrumentetion Totel fall-out collectors were set up on Enyu, Rukoji, a TNR tres rers arriixan, end Yokororyuru Islands. ‘On account of a failure in the timing circuit, the collector on Bokororyuru opereted before the shot. The collector on Enyu did not operate properly.’ Col- lectors on Rukoji and Arriikan operated proverly. xesults Conparisons of the aqueous and solid phases were made, however, @S shown in Table 2.6b-1. Additional data will be covered in Liter reports.: TABLE 2.6b-1 COMPARISON OF LIQUID VS SOLID FALL-OUT He eesees Pre we we em oe cation ~~~** 2044 *“Triikan _—— oreo Mo?? f£ecueous/Solid Ratio . 0.303 0.74 _, of o \ ——
