New Mexico Administrative Code › Title 20 - ENVIRONMENTAL PROTECTION › Chapter 3 - RADIATION PROTECTION › Part 15 - LICENSES AND RADIATION SAFETY REQUIREMENTS FOR IRRADIATORS › Section 20.3.15.7 - DEFINITIONS

Current through Register Vol. 35, No. 13, July 16, 2024
A. "Annually" means
				either: (1) at intervals not to exceed 1 year; or (2) once per year, at about
				the same time each year (plus or minus 1 month).
B. "Doubly encapsulated sealed source" means
				a sealed source in which the radioactive material is sealed within a capsule
				and that capsule is sealed within another capsule.
C. "Irradiator" means a facility that uses
				radioactive sealed sources for the irradiation of objects or materials and in
				which radiation dose rates exceeding 5 grays (500 rads) per hour exist at 1
				meter from the sealed radioactive sources in air or water, as applicable for
				the irradiator type, but does not include irradiators in which both the sealed
				source and the area subject to irradiation are contained within a device and
				are not accessible to personnel.
D.
				"Irradiator operator" means an individual who has successfully completed the
				training and testing described in 20.3.15.1517 NMAC, and is authorized by the
				terms of the license to operate the irradiator without a supervisor
				present.
E. "Panoramic
				dry-source-storage irradiator" means an irradiator in which the irradiations
				occur in air in areas potentially accessible to personnel and in which the
				sources are stored in shields made of solid materials. The term includes
				beam-type dry-source-storage irradiators in which only a narrow beam of
				radiation is produced for performing irradiations.
F. "Panoramic irradiator" means an irradiator
				in which the irradiations are done in air in areas potentially accessible to
				personnel. The term includes beam-type irradiators.
G. "Panoramic wet-source-storage irradiator"
				means an irradiator in which the irradiations occur in air in areas potentially
				accessible to personnel and in which the sources are stored under water in a
				storage pool.
H. "Pool irradiator"
				means any irradiator at which the sources are stored or used in a pool of
				water, including panoramic wet-source-storage irradiators and under water
				irradiators.
I. "Product conveyor
				system" means a system for moving the product to be irradiated to, from and
				within the area where irradiation takes place.
J. "Radiation room" means a shielded room in
				which irradiations take place. Under water irradiators do not have radiation
				rooms.
K. "Radiation safety
				officer" means an individual with responsibility for the overall radiation
				safety program at the facility.
L.
				"Sealed source" means any byproduct material that is used as a source of
				radiation and is encased in a capsule designed to prevent leakage or escape of
				the byproduct material.
M. "Seismic
				area" means any area where the probability of a horizontal acceleration in rock
				of more than 0.3 times the acceleration of gravity in 250 years is greater than
				10 percent, as designated by the U.S. geological survey.
N. "Underwater irradiator" means an
				irradiator in which the sources always remain shielded under water and humans
				do not have access to the sealed sources or the space subject to irradiation
				without entering the pool.
