| ultraviolet radiation | <physics> Invisible light, next to visible light in the electromagnetic spectrum. The most common source of ultraviolet radiation is the sun. Acronym: UV (16 Dec 1997) |
| K-radiation | Usually a very penetrating form of x-radiation excited by cathode rays (high speed electrons) impinging upon a metal anode such as tungsten; the energy of the radiation is a function of the binding energy of the K-shell electrons of the metal anode. (05 Mar 2000) |
| L-radiation | An x-radiation of slight penetrating power excited by cathode rays (high speed electrons) impinging on a metal anode; the energy of the radiation is a function of the binding energy of the L-shell electrons of the metal anode. (05 Mar 2000) |
