WebAug 27, 2015 · Gas-filled detectors (such as Geiger counters and ion chambers) are filled with a gas that has an electrical voltage applied across it. When radiation interacts with the gas it causes ionizations, and this small signal is amplified by the electrical voltage – the amount of amplification depends on the voltage. Weband gamma rays (γ). α particles are the least energetic, most massive of these decay products. An α particle contains two protons and two neutrons, and thus comprises a stable helium nucleus. α particles only weakly penetrate whatever matter they encounter. They are unable to penetrate even 10 cm of air. β particles are high energy electrons.
