__
To determine the contamination and decbrtamination characteristics of representative harbor area construction
surfaces and coatings
when exposed to fall-out from surface detonatiions over shallow water
and land. Farticular interest is concentratedon the wet contaminating
particles since no field studies have been conductéd under these conditions.
5.5.2
Procedure
A set of 14 construction material panels, 4 ft square, will be
mounted on each drone liberty ship of Project 6.4 which will operate
in the heavy fall-out areas of Shots Bravo, Union, Koon, and Yarikee.
When the ships are returned to niwetok between shots the panels will
be removed to Parry Island fcr various types of decontamination~
procedures with intermittent radiation level readings being taken for
analysis to determine applicability of the different decontamination
