Frigörelse av radioaktivt silver (Ag-108m) från styrstavar hade en stor betydelse i vissa microbial sulfide-producing activity in Calcigel bentonite at saturated
Target foil stacks of silver were bombarded with beams of alpha particles at incident energies ≤90 MeV. Cumulative cross sections for the production of 104(m+g) Ag, 105(m+g) Ag, 106m Ag, 108m Ag, 110m Ag and 111(m+g) Ag were determined by semiconductor gamma-spectrometry of the residual activity of stacked foils.

The other studied nuclides are C-14, Cl-36, Mo-93, Ag-108m and I-129 as they are the nuclides propagating to biosphere in the TURVA-2012 safety case of Posiva during a 10000 year study time of spent nuclear fuel final disposal in Finland [5]. In all presented figures the coloring and notation is as follows. The mean of the base data (5). Lithium impurities contribute substantially to the production of tritium, due to the large (n,α) cross section of Li-6.

The analysis will be performed for isotopes Ag-108m and Co-60 since they are considered typical for this type of waste material. Two of the 20 drums having result of the summation formula after cementation between 1.0 and 1.6 will be used to make blocks. The specific activity of Ag-108m in first one is 1.2 Bq/g and of Co-60 in the second is 0.7

After a short period in storage the produced Silver is almost entirely stable and safe to use.

614.4 (91). Ag-108m. 722.9*(91). Most silver is produced as a by-product of copper, gold, lead, and zinc mining.
One prerequisite of the removal step was that it should not slow down the process; the radioiodine removal was thus tested at the same flowrates applied during the process.

In this case, the production of effluent will be minimised (no work is carried out). On the other hand, a unit shutdown for a long time (decennial shut-down, typically) will show an increase in the production of effluent and a decrease in the power supplied. During the next year, these two scenarios may be reversed.
