South Carolina Code of Regulations › Chapter 61 - DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL › Subchapter 61-63 - Radioactive Materials (Title A) › Part XI - LICENSING AND RADIATION SAFETY REQUIREMENTS FOR IRRADIATORS › Section 61-63.XI.RHA 11.2 - Definitions

Current through Register Vol. 48, No. 6, June 28, 2024
11.2.1 "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).
11.2.2 "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.
11.2.3 "Irradiator" means a
				facility that uses radioactive sealed sources for the irradiation of objects or
				materials and in which radiation dose rates exceeding 500 rads (5 grays) 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.
11.2.4
				"Irradiator operator" means an individual who has successfully completed the
				training and testing described in
				RHA
				11.18 and is authorized by the terms of the license to
				operate the irradiator without a supervisor present.
11.2.5 "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.
11.2.6 "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.
11.2.7 "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.
11.2.8 "Pool irradiator" means any
				irradiator at which the sources are stored or used in a pool of water including
				panoramic wet-source-storage irradiator and underwater irradiators.
11.2.9 "Product conveyor system" means a system
				for moving the product to be irradiated to, from and within the area where
				irradiation takes place.
11.2.10
				"Radiation room" means a shielded room in which irradiations take place. Underwater
				irradiators do not have radiation rooms.
11.2.11 "Radiation safety officer" means an
				individual with responsibility for the overall radiation safety program at the
				facility.
11.2.12 "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.
11.2.13 "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.
11.2.14
				"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.
