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.
Stray radiation means the sum of leakage and scattered radiation.
Palliative care means medical service rendered to reduce or moderate temporarily the intensity of an otherwise stable medical condition, but does not include those medical services ren- dered to diagnose, heal or permanently alleviate or eliminate a medical condition.
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.
Irradiation means the exposure of a living being or matter to ionizing radiation.
Ionizing radiation means gamma rays, x-rays, alpha and beta particles, high speed electrons, protons, neutrons, and other nuclear particles;
Stationary beam radiation therapy means radiation therapy without displacement of one or more mechanical axes relative to the patient during irradiation.
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.
associated facilities means all associated track structures, over and under track structures, supports (including supports for equipment or items associated with the use of the Network), tunnels, bridges, train control systems, signalling systems, communication systems and associated plant, machinery and equipment from time to time but only to the extent that such assets are related to or connected with the Network but does not include any sidings or yards;
Basic generation service or "BGS" means electric generation
Cannabis plant means any plant of the genus Cannabis;
Related facilities means any ancillary facilities owned by the Company which are —
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.
External beam radiation therapy means therapeutic irradiation in which the source of radiation is at a distance from the body.
Radiation machine means any device capable of producing radiation except those devices with radioactive material as the only source of radiation.
Radiation therapy simulation system means a radiographic or fluoroscopic x-ray system intended for localizing the volume to be exposed during radiation therapy and confirming the position and size of the therapeutic irradiation field.
Cheating means intentionally misrepresenting the source, nature, or other conditions of academic work so as to accrue undeserved credit, or to cooperate with someone else in such misrepresentation. Such misrepresentations may, but need not necessarily, involve the work of others. Cheating includes, but is not limited to:
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.
Limited common areas and facilities means those common areas and facilities
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.
