Swelling and outgassing of heavily-irradiated lithium hydride

Outgassing from alpha particle irradiation of lithium hydride and lithium hydroxide

“…At some pressure, the bubbles rupture and H 2 outgasses from the material. Several studies have directly measured H 2 outgassing as an effect of radiation: Mikhailov (1983), while irradiating single crystal LiH with ultraviolet light; , , , and Emig et al (1990), while studying b-radiation effects in polycrystalline lithium tritide (LiT) or lithium deuteride/tritide (LiD/T) [8][9][10][11][12]. Studies of neutron-irradiated LiH have shown evidence of H 2 outgassing, however, the outgassing was never clearly attributable to LiH radiolysis [13,14].…”
