Everyday use of alpha radiation
WebMay 22, 2024 · How is alpha radiation used in everyday life? Uses. Americium-241, an alpha emitter, is used in smoke detectors. Alpha decay can provide a safe power source for radioisotope thermoelectric generators used for space probes and were used for artificial heart pacemakers. WebAlpha particles, with a mass of about 4.01506 u (6.644657 × 10 − 27 kg), are highly ionizing. Alpha particles are emitted from nuclei with distinctive discrete energies, which enable spectroscopic identification of α -particle emitting radioisotopes. Ranges in matter vary, but are generally short because of the high stopping power ( − dE ...
