It appears on the basis of somewhat limited inforimation available that has an organic brain syndrome, possibly Alzheimer's Disease. The patient is currently undergoing comprehesive inpatient evaluation at one of the U. S. Public Health Service Hospitals, In the Able and Baker tests was assigned to the USS Avery Island -- Electronics Coordinating Cffice, Code 965. It would appear that in some of his duties was obliged to board target vessels after clearance to check on the degree of damage sustained by instruments in the radio shacks. we had assumed that all personnel wore film badges or dosimeters of some type as there was a potentiality that they would be significantly exposed. The Navy apparently has no retained records showing whether or not this civilian was wearing a film badge. We have come up with negative results to date from Colonel Bache's office. For this reason would you furnish us in general terms a statement relating to the radiation exposures of this claimant on Crossroads Operations? \.e have been civen to understand that no individual participating in the operation had an exposure exceedinr o.1 Roentgen per day. Your comments on this problem would be appreciated, including citations which present a fuller ciscussion of this radiological safety problem.
