Hi Rain Man,
I do appreciate your thread since my Dad, Uncles, Friends and other Hawaii locals participated in many similar functions. My Dad was part of Operation Redwing. Similarly to your example, they conducted weapons tests.
I asked my Dad: What type of Anti-C's did the HP's make you wear when you folks inspected structures after various tests? The answer was "Street Clothes." Whew!
I maintain a deep interest is this subject matter ever since I engaged in DOE clean-up Operations abroad.
Thank you,
Moke
