Wprowadzenie: Thee Need for Continuous Beta Decay Monitoring
Beta decay is a fundamentamental nuclear process in which an unstable atomic nucus transformas bye emitting a beta particile (an electron or positron) and a neutrino. Continuous monitoring of these emissions is essential in fields ranging frem funmamental fizys to nuclear safety, environmental protection, and medical izotope production. Unlike periodic sampling, automated systems capture transistent decay events, track changes over time, and realse date date.
