OAR 333-121-0010
Definitions
(1)
“Annually” means at intervals not to exceed one year.(2)
“Commencement of construction” means taking any action defined as “construction” or any other activity at the site of a facility subject to the regulations in this division that has a reasonable nexus to radiological health and safety.(3)
“Construction” means the installation of foundations, or in-place assembly, erection, fabrication, or testing for any structure, system, or component of a facility or activity subject to the regulations in this division that are related to radiological safety or security. The term “construction” does not include:(a)
Changes for temporary use of the land for public recreational purposes;(b)
Site exploration, including necessary borings to determine foundation conditions or other preconstruction monitoring to establish background information related to the suitability of the site, the environmental impacts of construction or operation, or the protection of environmental values;(c)
Preparation of the site for construction of the facility, including clearing of the site, grading, installation of drainage, erosion and other environmental mitigation measures, and construction of temporary roads and borrow areas;(d)
Erection of fences and other access control measures that are not related to the safe use of, or security of, radiological materials subject to this division;(e)
Excavation;(f)
Erection of support buildings (such as construction equipment storage sheds, warehouse and shop facilities, utilities, concrete mixing plants, docking and unloading facilities, and office buildings) for use in connection with the construction of the facility;(g)
Building of service facilities (such as paved roads, parking lots, railroad spurs, exterior utility and lighting systems, potable water systems, sanitary sewerage treatment facilities, and transmission lines);(h)
Procurement or fabrication of components or portions of the proposed facility occurring at other than the final, in-place location at the facility; or(i)
Taking any other action that has no reasonable nexus to radiological health and safety.(4)
“Doubly encapsulated sealed source” means a sealed source in which the radioactive material is sealed within an inner capsule and that capsule is sealed within an outer capsule.(5)
“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.(6)
“Irradiator operator” means an individual who has successfully completed the training and testing described in OAR 333-121-0300 (Training) and is authorized by the terms of the license to operate the irradiator without a supervisor present.(7)
“Irradiator operator supervisor” means an individual who meets the requirements for an irradiator operator and who physically oversees operation of the irradiator by an individual who is currently receiving training and testing described in OAR 333-121-0300 (Training).(8)
“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.(9)
“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.(10)
“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)
“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 underwater irradiators.(12)
“Product conveyor system” means a system for moving the product to be irradiated to, from, and within the area where irradiation takes place.(13)
“Radiation room” means a shielded room in which irradiations take place. Underwater irradiators do not have radiation rooms.(14)
“Sealed source” means any radioactive 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.(15)
“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 US Geological Survey.(16)
“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.
