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
Clothing and/or equipment worn by workers (including first responders and first receivers) to prevent or mitigate job-related illness or injury. Individual ppe elements can include respiratory and percutanous protective equipment.
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 naturally occurring radioactive metal found in small amounts in soil, rock, water, plants, and animals. The most common isotopes of thorium are thorium-232 (th-232), thorium-230 (th-230), and thorium-238 (th-238).
Industry:Medical devices
A brown to black mineral that has a distinctive luster. It consists mainly of uraninite (uo2), but also contains radium (ra). It is the main source of uranium (u) ore.
Industry:Medical devices
The sum of effective dose equivalent from external radiation and the committed effective dose equivalent from inhaled and ingested radioactive material. Quoted in units of rem.
Industry:Medical devices
The material spreading from a particular source and travelling through environmental media, such as air or ground water. For example, a plume could describe the dispersal of particles, gases, vapors, and aerosols in the atmosphere, or the movement of contamination through an aquifer (for example, dilution, mixing, or adsorption onto soil).
Industry:Medical devices
Pertaining to elements with atomic numbers higher than uranium (92). For example, plutonium (pu) and americium (am) are transuranics.
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 kilogramme is equivalent to about 22 million kilowatt-hours of heat energy. The complete detonation of a kilogramme of plutonium produces an explosion equal to about 20,000 tonnes of chemical explosive. All isotopes of plutonium are readily absorbed by the bones and can be lethal, depending on the dose and exposure time.
