United States Department of Health and Human Services, Radiation Emergency Medical Management
A “hydrogen bomb.” A device with explosive energy that comes from fusion of small nuclei, as well as fission.
Industry:Medical devices
Radiation that can penetrate the skin and reach internal organs and tissues. Photons (gamma rays and x-rays), neutrons, and protons are penetrating radiations. However, alpha particles and all but extremely high-energy beta particles are not considered penetrating radiation.
Industry:Medical devices
Birth defects that are not passed on to future generations, caused by exposure to a toxin as a fetus. See also genetic effects, somatic effects.
Industry:Medical devices
Radiation emitted by naturally occurring radioactive materials, such as uranium (u), thorium (th), and radon (rn) in the earth.
Industry:Medical devices
A discrete "packet" of pure electromagnetic energy. Photons have no mass and travel at the speed of light. The term "photon" was developed to describe energy when it acts like a particle (causing interactions at the molecular or atomic level), rather than a wave. Gamma rays and x-rays are photons.
Industry:Medical devices
A heavy, man-made, radioactive metallic element. The most important isotope is pu-239, which has a half-life of 24,000 years. Pu-239 can be used in reactor fuel and is the primary isotope in weapons. One kilogram is equivalent to about 22 million kilowatt-hours of heat energy. The complete detonation of a kilogram of plutonium produces an explosion equal to about 20,000 tons of chemical explosive. All isotopes of plutonium are readily absorbed by the bones and can be lethal, depending on the dose and exposure time.
Industry:Medical devices
A radioactive chemical element and a product of radium (ra) decay. Polonium is found in uranium (u) ores.
Industry:Medical devices
A nucleus that contains an uneven number of protons and neutrons and seeks to reach equilibrium between them through radioactive decay (i.e., the nucleus of a radioactive atom). See also stable nucleus.
