Radiation energy is typically expressed in electronvolts (eV), kiloelectronvolts (keV), or megaelectronvolts (MeV). These units correspond to the amount of energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt.

Using these specific units is crucial in the field of radiation for several reasons. First, they are particularly relevant in the context of quantum mechanics and are often used to describe the energy levels of photons and particles in fields such as nuclear physics and medical radiation.

Electronvolts, in particular, are convenient for expressing the energy of small particles or photons, as these energy values are typically quite small on a macroscopic scale. For example, the energy of visible light is generally measured in the range of a few eV, making it an appropriate unit for this context.

Units like Hertz, which measure frequency, are related to energy through the relationship E = hf (where h is Planck's constant), but they do not directly measure energy like eV and its derivatives. Similarly, units like Joules or those related to power (such as Watts) are not typically used in the same contexts as eV, keV, or MeV when
