A test to determine the amounts of radioactive materials through the detection of ionizing radiation. Radioassays will detect transuranic nuclides, uranium, fission and activation products, naturally occurring radioactive material, and medical isotopes.
Industry:Medical devices
Health effects caused by exposure to ionizing radiation.
Industry:Medical devices
1) medical: the use of radiant energy (such as x-rays and gamma rays) to image body systems; 2) industrial: the use of radioactive sources to photograph internal structures, such as turbine blades in jet engines. A sealed radiation source, usually iridium-192 (ir-192) or cobalt-60 (co-60), beams gamma rays at the object to be checked. Gamma rays passing through flaws in the metal or incomplete welds strike special photographic film (radiographic film) on the opposite side.
Industry:Medical devices
Isotopes of an element that have an unstable nucleus. Radioactive isotopes are commonly used in science, industry, and medicine. The nucleus eventually reaches a stable number of protons and neutrons through one or more radioactive decays. Approximately 3,700 natural and artificial radioisotopes have been identified.
Industry:Medical devices
Related to radioactive materials or radiation. The radiological sciences focus on the measurement and effects of radiation.
Industry:Medical devices
The luminescence produced by particles emitted during radioactive decay. (chemical/biological/radiological incident handbook, central intelligence agency)
Industry:Medical devices
A device that disperses radioactive material by conventional explosive or other mechanical means, such as a spray. See also dirty bomb.
Industry:Medical devices
Also called a "hidden sealed source." an red is a terrorist device intended to expose people to significant doses of ionizing radiation without their knowledge. Constructed from partially or fully unshielded radioactive material, an red could be hidden from sight in a public place (e.g., under a subway seat, in a food court, or in a busy hallway), exposing those who sit or pass close by. If the seal around the source were broken and the radioactive contents released from the container, the device could become a radiological dispersal device (rdd), capable of causing radiological contamination.

Industry:Medical devices
An unstable and therefore radioactive form of a nuclide.
Industry:Medical devices
A naturally occurring radioactive metal. Radium is a radionuclide formed by the decay of uranium (u) and thorium (th) in the environment. It occurs at low levels in virtually all rock, soil, water, plants, and animals. Radon (rn) is a decay product of radium.
