The film badges of three men indicated exposures of 859 95, and 96 R.
These individuals are believed to have worked aboard an LCM alongside the
Belle Grove.
During the washdown of the Belle Grove, consiflerable water
reportedly accumulated in the LCM alongside.
Subsequently,| these individ-
uals were believed to have worked on decontaminating the LCE.
Their expo-
sures were reportedly a result of concentrated fallout in tHe LCM.

The destroyer minelayer USS Shea, the salvage vessel USS
Explosive Ordnance Disposal Unit 1, Naval Beach Group 1, and

only for the conduct of Project 3.4, Sea Minefield Neutralizatlion by Means

seven strings of mines, containing 121 in all, at specified dibtances from
ground zero.
The mines were inert-loaded, but otherwise functfonal, with
a detonator installed to assess the shot's effects on the mines components.
After the shot, the Mine Laying and Recovery Element,
recovered 100 mines and turned them over to the Mine Readying
