Radiation chemistry of synthetic waste

Radiolytic and radiolytically induced generation of gases from synthetic wastes. Final report

“…Nitrogen is also generated and organics are required for its production, but N 2 0 is not a major source of N 2 . Ammonia is produced by the radiolysis of a degradation product of the original chelators; the yield of NH 3 increases linearly with dose, and the nitrogen atom in NH 3 comes from the organic chelator.…”

“…With sufficient information, one could then propose strategies to substantially decrease the buildup of hazardous gas mixtures.-This report summarizes the sults and conclusions of this effort. Interim reports have been issued, 1 ' 2 including a literature report, 3 and these will be frequently referred to here.…”

“…The resultant solution was covered with a watch glass, wrapped with aluminum foil, and stirred at 60-70 0 C overnight. The final molarities of the various components based on the density of the slurry, 1.56 g/cm 3 , as provided by Bryan, are given in Table E2-1. However, we consistently find the density to be slightly higher, 1.60 g/cm 3 , and use this value to calculate the absorbed dose.…”

However, we consistently find the density to be slightly higher, 1.60 g/cm 3 , and use this value to calculate the absorbed dose. For thermal generation experiments using preirradiated samples, the preirradiations were performed in covered (but not gas-tight) stainless steel beakers.…”

“…Small yields of ammonia were measured and the yields increase linearly with dose indicating that the ammonia is produced from radiolysis of an intermediate. The nitrogen in NH 3 comes from organic chelators, such as EDTA.…”
