Question

what is the unit of measurement for photon energy?
grays (gy)
sieverts (sv)
kilovoltage peak (kvp)
kiloelectron volts (kev)

Explanation:

Grays (Gy) measure absorbed dose of ionizing radiation. Sieverts (Sv) measure equivalent dose considering biological effects of radiation. Kilovoltage peak (kVp) is a measure of the peak potential difference in an X - ray tube. Kiloelectron volts (keV) is a unit of energy, and photon energy is measured in electron - volts (eV) or its multiples like keV.

Answer:

D. Kiloelectron volts (keV)
