Web23 de nov. de 2004 · High-energy electrons in the magnetosphere also emit x-rays and radio waves, in their own style. Positive ions, being heavier, tend to move more slowly and to radiate less efficiently. To produce x-rays or gamma rays, electrons must collide with some more massive target. WebApril 3rd, 2015 By Mirion Technologies. Ionizing radiation takes a few forms: Alpha, beta, and neutron particles, and gamma and X-rays. All types are caused by unstable atoms, which have either an excess of energy or mass (or both). In order to reach a stable state, they must release that extra energy or mass in the form of radiation. WebEmitted spectrum of thorium: Energy, some of it in the form of visible light, is emitted when thorium is exposed to a source of energy itself, such as a cathode ray, heat, or ultraviolet light. This effect is shared by cerium dioxide, which converts ultraviolet light into visible light more efficiently, but thorium dioxide gives a higher flame temperature, emitting less … flushing house assisted living queens ny
