Grenz rays are a form of black light. Similar to ultraviolet light, x-rays, and gamma rays, these are all composed of photons, which are packets of electro-magnetic energy traveling at the speed of light. Grenz rays are produced at low kilovoltages giving them a very low penetration power. Half their energy is absorbed within the first half millimeter of tissue, which means that they do not penetrate beneath the skin.

OBS

Grenz rays ... are sometimes called Bucky rays, after Bucky, who established their value as a therapeutic agent.

OBS

The word "grenz" comes from the German "grenze" meaning "border". The grenz rays were considered to be in a gray zone between x-rays and ultraviolet radiation by early investigators.

OBS

grenz ray; Bucky ray: terms usually used in the plural.
