The vast majority of produced Silver is Ag-109 which is stable, and Ag 111 which decays away very quickly to form Cd 111. The only radioactive isotope with a significant half life is Ag-108m (418 years) but it is only formed in trace quantities. After a short period in storage the produced Silver is almost entirely stable and safe to use.

The silver consisted of equal amounts of Ag-107 and Ag-109. The absorption of the neutrons by the silver converted some of the Ag-107 to Ag-108m (400+ year half-life) and Ag-108 (2.39 min half life).

It was the world’s first plutonium production reactor, (Ho-166m), silver (Ag-108m), and barium (Ba-133) are in evidence. Am-241 is present at a low concentration; on the basis of its 59-keV gamma line I cannot confidently estimate its concentration using the Cs-137 reference source technique.

By special arrangement with Colleen French, the DOE’s park coordinator at B Reactor, I was able to visit the reactor at my own pace with a small group of nuclear enthusiasts in March. "Survey" means an evaluation of the radiological conditions and potential hazards incident to the production, use, transfer, release, disposal, or presence of sources of radiation. When appropriate, such evaluation includes, but is not limited to, tests, physical examinations, and measurements of levels of radiation or concentrations of radioactive material present. $\begingroup$ @Kaylyn, that depends on the radioactive decay chain. Turns out the majority of radioactive silver isotopes decay via beta minus decay.
