👉 The term "kilorad" refers to a unit of radiation energy. It is commonly used in physics and astronomy, where it represents the amount of radiation emitted per unit time or area. In simple terms, it is like how much light or sound one meter of a wall emits in one second. Kilorads are often expressed in units like "keV" (kelectron volts), which is equivalent to 10^3 joules per second.
