Gamma ray is a type of radiation that has no mass & no charge. Gamma rays have a high penetrating power. Text us. Tags: gamma ray, radiation, mass. Wednesday, February 01 2012.
Best Answer: Yes, it does, technically. According to thermal radiation theory (first link), any mass not at absolute zero will eventually radiate energy away from its surface. This radiation is a form of heat (the others being convection and conduction). Since the moon is a mass, a large one at that, and is not at absolute zero temperature, it must emit thermal radiation. The second link shows a white paper discussing the topic in detail and even given the radiation's physical power: the exceedingly low energy wavelength of roughly 1.25cm.
