- Summary
- Container materials for short-lived transuranium nuclides such as /sup 242/Cm and /sup 252/Cf may be implanted with sufficiently high concentrations of helium to cause surface blistering and other deleterious effects in some environments. Platinum and stainless steel surfaces adjacent to solid /sup 242/Cm-oxide deposits showed no blisters after room-temperature exposures, but formed porous, distorted layers on postexposure heating. Platinum surfaces adjacent to solid /sup 252/Cf-oxide deposits, in contrast, developed well-defined blisters with a variety of configurations during room-temperature exposures. Formation of the blisters at low temperatures was attributed to the fission-fragment-induced agglomeration of implanted helium, coupled with a stress-relieving transport of atoms displaced by fission fragments into the blister walls. High-temperature exposures produced less well-defined globular protrusions at much lower concentrations of implanted helium. Immersion of glass or platinum specimens in dilute /sup 242/Cm or /sup 252/Cf solutions caused no significant surface damage, and on subsequent reaction with acidic or caustic reagents other than HF, the surfaces displayed no well-defined effect of the radiation exposures. HF solutions preferentially etched fission tracks in /sup 252/Cf-exposed glass specimens. No significant retention of /sup 252/Cf implanted in container surfaces by fission fragment impact was detected.
