_ byt Hee as Project 2.66 — RADIOCHEMICAL ANALYSIS OF SURFACE CONTAMINATION os Project Officer - R. C. Tompkins Ob jectives The objectives of this work were to study the distribution of certain nuclides within fall-out particles and to determine some of the differences in radiochemical properties between liquid and solid fall-out. = Instrunentation = Total fall-out collectors were set up on the lagoon phototower (Mack), = the Project 6.5 barge, Engebi, and Bokonaarappu. Only the collector on Engebi and the phototower wre fully instrumented with collecting solutions. The phototower station failed to operate because of a circuit failure. Of the other stations, only Engebl gave a sufficient sample to work with. In addition, a soil sample was obtained from Bogallua, 2 Results . Data have not been received from the test site, -£1- ik
