0 a photon (= a unit of light) that is produced in gamma radiation (= a type of radiation with a very short wavelength that passes through most solid objects) -- 伽玛粒子
Mg decays by the emission of a high-energy beta or gamma particle, which can be measured using a scintillation counter.
Gamma particles penetrate deep into the body and are undoubtedly hazardous.
With nuclear waste, alpha, beta and gamma particles are emitted.
Electron recoils are produced by alpha, beta and gamma particles which account for the vast majority of background events.
