That’s really neat, Geo. I never cease to be amazed at your breadth of knowledge, as well as that of other members in this group of “amateur” scientists. Happy Holidays, everyone -- Ken Sent:

Cool Ken. Very much on-topic for this group, thanks. Neutron activation is something we run in to during Trinitite testing (Eu and Ba, not to mention Pu-241>Am-241) Stellite, interesting you should

Hi Geo, Yes and No. Analysis was mostly BEFORE the fact. Co-60 was the bane of our existence, as it easily accounted for probably 80% or more of our collective radiation dose at the plant. The high

As an interesting aside to the bromine discussion – When I worked at a nuclear power plant a few years ago, we were consistently seeing airborne Bromine-82 in air samples collected from only one of

Bromine- remember bromine is used extensively in electronics as a flame retardant in printed circuit boards. and clothing too. Geo To: [email protected] Sent: Sunday, December 6, 2020 10:52:32 PM Subject:

Well I stretched my imagination but I’m not convinced there’s any Zn. Try a used oil. I may be the levels are too low to pull out dud Sent: Sunday, December 6, 2020 9:07 PM To: [email protected]

" In my attempt to take a snapshot of the oil, I spilled some on the floor and on my pants." Had to laugh a little.

Yes I too just re-read the Los Alamos Primer Steve. So far the mention of gold in the gadget eludes me but the mention of gold-leaf neutron detectors showed up. Nonetheless, our all-metal pieces and

According to the Serber paper, gold was one of the top candidates for a tamper material. I don't think gold would be something normally analyzed for when studying trinitite, so who knows?

Gold? hmmmmmmmm.... one reference mentions the quantity of gold that was used in the gadget, not something we normally think about. That would be quite the find. To: [email protected], "WILLIAM S Dubyk"
