Stray radiation means the sum of leakage and scattered 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.
Radiation machine means any device capable of producing radiation except those devices with radioactive material as the only source of radiation.
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.
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.
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.
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.
Irradiation means the exposure of a living being or matter to ionizing radiation.
Clinical nurse specialist means a registered nurse with relevant post-basic qualifications and 12 months’ experience working in the clinical area of his/her specified post-basic qualification, or a minimum of four years’ post-basic registration experience, including three years’ experience in the relevant specialist field and who satisfies the local criteria.
Secondary dose monitoring system means a system which will terminate irradiation in the event of failure of the primary dose monitoring system.
Cannabis retailer means any licensed person or entity that purchases or otherwise obtains usable cannabis from cannabis cultivators and cannabis items from cannabis manufacturers or cannabis wholesalers, and sells these to consumers from a retail store, and may use a cannabis delivery service or a certified cannabis handler for the off-premises delivery of cannabis items and related supplies to consumers. A cannabis retailer shall also accept consumer purchases to be fulfilled from its retail store that are presented by a cannabis delivery service which will be delivered by the cannabis delivery service to that consumer.
