WebAug 1, 2024 · Thorium is radioactive itself, emitting alpha particles. The resulting "daughter" products of that radioactive decay series also produce both alpha and beta particles. This decay process means these thoriated glass lenses can gradually become more radioactive over time, as the more highly radioactive decay products build up in the glass. WebApr 11, 2024 · Concepts of various Earth systems and feedbacks between systems were highlighted. For example, the deep biosphere, hosted in photon-deprived, kilometer-deep domains in the lithosphere, are nurtured (e.g., water radiolysis) by energetic particles from alpha and beta decays, produced by the surrounding rocks, and cosmic ray produced … eye lids very dry and raw
