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. A unit of electrical energy, particularly for utility bills, is the kilowatt-hour (kWh); one kilowatt-hour is equivalent to 3.6 megajoule. Electricity usage is often given in units of kilowatt-hours per year or other time period. This is actually a measurement of average power consumption, meaning the average rate at which energy is transferred. One kilowatt-hour per year is about 0.11 watts.
