Web23 jul. 2024 · There are four different types of radiation: alpha, beta, gamma and neutron. Since each one has different properties, each one of them is measured a bit differently. Alpha radiation is measured by a GM pancake probe or a zinc sulfide scintillator; Beta radiation is measure using a GM pancake probe, a beta scintillator or an ion chamber WebIonizing radiation can be measured using units of electron volts, ergs, and joules. The electron-volt (abbreviated eV) is a unit of energy associated with moving electrons around. An electron is “tightly bound” in a hydrogen atom (one proton and one electron). It takes energy to move this electron away from the proton.
