P-100 filtering face piece disposable particulate respirators are capable of filtering at least 99.97% of airborne particles measuring ≥0.3 micron in diameter. Filtering face piece respirators designated with a "p" are strongly resistant to oil.
Industry:Medical devices
Waste rock from mining operations that contains concentrations of mineral ore that are too low to make typical extraction methods economical.
Industry:Medical devices
The routes by which people are exposed to radiation or other contaminants. The three basic pathways are inhalation, ingestion, and direct external exposure. See also exposure pathway.
Industry:Medical devices
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
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).
