Useful radiation or "primary beam" means radiation that passes through the window, aperture, cone, or other beam limiting device of the tube or source housing.
Useful radiation or "primary beam" means radiation that passes through the
Stray radiation means the sum of leakage and scattered radiation.
Ionizing radiation means gamma rays, x-rays, alpha and beta particles, high speed electrons, protons, neutrons, and other nuclear particles;
Very high radiation area means an area, accessible to individuals, in which radiation levels from radiation sources external to the body could result in an individual receiving an absorbed dose in excess of 5 Gy (500 rad) in one hour at one meter from a source of radiation or one meter from any surface that the radiation penetrates.
ionising radiation means the transfer of energy in the form of particles or electromagnetic waves of a wavelength of 100 nanometres or less or a frequency of 3 x 1015 hertz or more capable of producing ions directly or indirectly;
High radiation area means an area, accessible to individuals, in which radiation levels from radiation sources external to the body could result in an individual receiving a dose equivalent in excess of one mSv (0.1 rem) in one hour at 30 centimeters from any source of radiation or 30 centimeters from any surface that the radiation penetrates.
Irradiation means the exposure of a living being or matter to ionizing radiation.
Radiation means alpha particles, beta particles, gamma rays, X-rays, neutrons, high-speed electrons, high-speed protons, and other particles capable of producing ions. For purposes of these rules, ionizing radiation is an equivalent term. Radiation, as used in these rules, does not include nonionizing radiation, such as radiowaves or microwaves, visible, infrared, or ultraviolet light.
Radiation area means any area, accessible to individuals, in which radiation levels could result in an individual receiving a dose equivalent in excess of 0.05 mSv (0.005 rem) in 1 hour at 30 centimeters from the source of radiation or from any surface that the radiation penetrates.
Moving beam radiation therapy means radiation therapy with any planned displacement of radiation field or patient relative to each other, or with any planned change of absorbed dose distribution. It includes arc, skip, conformal, intensity modulation and rotational therapy.
External beam radiation therapy means therapeutic irradiation in which the source of radiation is at a distance from the body.
Leakage radiation means radiation emanating from the diagnostic source assembly except for:
Background radiation means radiation from cosmic sources; naturally occurring radioactive materials, including radon (except as a decay product of source or special nuclear material); and global fallout as it exists in the environment from the testing of nuclear explosive devices or from past nuclear accidents such as Chernobyl that contribute to background radiation and are not under the control of the licensee. “Background radiation” does not include sources of radiation from radioactive materials regulated by the agency.
Source of radiation means any radioactive material or any device or equipment emitting, or capable of producing, radiation.
Stationary beam radiation therapy means radiation therapy without displacement of one or more mechanical axes relative to the patient during irradiation.
Plasma arc incinerator means any enclosed device using a high intensity electrical discharge or arc as a source of heat followed by an afterburner using controlled flame combustion and which is not listed as an industrial furnace.
Fluoroscopic imaging assembly means a subsystem in which X-ray photons produce a visual image. It includes the image receptor(s) such as the image intensifier and spot-film device, electrical interlocks, if any, and structural material providing linkage between the image receptor and diagnostic source assembly.
Radiation therapist means a person, other than a Licensed Practitioner or Nuclear Medicine Technologist, who applies radiation to humans for therapeutic purposes under the supervision of a Licensed Practitioner;
Analytical x-ray equipment means equipment used for x-ray diffraction or fluorescence analysis.
High global warming potential hydrofluorocarbons means any hydrofluorocarbons in a particular end use for which EPA’s Significant New Alternatives Policy (SNAP) program has identified other acceptable alternatives that have lower global warming potential. The SNAP list of alternatives is found at 40 CFR part 82, subpart G, with supplemental tables of alternatives available at (http://www.epa.gov/snap/ ).
Therapy means the administration of drugs or chemicals to remove toxic concentrations of metals from the body.
CAFRA Centers, Cores or Nodes means those areas with boundaries incorporated by reference or revised by the Department in accordance with N.J.A.C. 7:7-13.16.
Fuel burning equipment means any furnace, boiler, apparatus, stack and all associated equipment, used in the process of burning fuel.
Radiation machine means any device capable of producing radiation except those devices with radioactive material as the only source of radiation.
Airborne radioactivity area means a room, enclosure, or area in which airborne radioactive materials, composed wholly or partly of licensed material, exist in concentrations:
Low-level radioactive waste or “waste” means radioactive material that consists of or contains class A, B, or C radioactive waste as defined by 10 C.F.R. 61.55, as in effect on January 26, 1983, but does not include waste or material that is any of the following:
Radiation detector means a device which in the presence of radiation provides a signal or other indication suitable for use in measuring one or more quantities of incident radiation.
