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.

"WebRadiation is often measured as a dose over a specific period of time, known as the dose rate. For example, the typical dose rate from natural background radiation in Australia is 1,500 to 2,000 μSv per year, or equivalently, 4 to 5 μSv per day. The actual exposure received depends on both the dose rate and the exposure time. " - Total rate of radiation of energy
