This paper redefines the essence of radiation and excludes electromagnetic waves from the category of radiation. Electromagnetic waves are pure field oscillations, while radiation is essentially the directional motion of massive photino clusters. The equivalent mass of the minimum infrared photino cluster is derived in this work. On this basis, the mass gradient of photino clusters in ultraviolet, X-ray and gamma-ray bands is calculated, which perfectly matches the law of biological radiation damage. This paper also denies the unreasonable mainstream photon mass model, and maintains the logical self-consistency of the theoretical system.
