Ionising ability of alpha particles
Web4 apr. 2024 · The legacy of the early days of the Atomic Age consists of many problematic sites worldwide, including radioactive waste dumps, uranium mines, spent fuel reprocessing plants, and defunct processing and enrichment plants. Although nature quickly reclaims abandoned sites, any remaining radioisotopes can pose a threat for millennia to come, … Web8 mei 2024 · Alpha radiation ionises the air and this allows a small current to flow between two electrodes. Alpha is weakly penetrating so smoke stops it, the current drops and the alarm goes off. Why is alpha particles used in smoke detectors? Alpha particles from the americium source ionize air molecules.
