Section XV-1703 - Definitions

A. As used in this Chapter, the following definitions apply. Other definitions applicable to this Chapter may be found in LAC 33:XV.Chapters 1 and 2.

Annually- at intervals not to exceed one year.

Doubly Encapsulated Sealed Source- a sealed source in which the radioactive material is sealed within an inner capsule and that capsule is sealed within an outer capsule.

Irradiator- 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.

Irradiator Operator- an individual who has successfully completed the training and testing described in LAC 33:XV.1735 and is authorized by the terms of the license to operate the irradiator without a supervisor present.

Irradiator Operator Supervisor- 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 LAC 33:XV.1735.

Panoramic Dry-Source-Storage Irradiator- 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.

Panoramic Irradiator- an irradiator in which the irradiations are done in air in areas potentially accessible to personnel. The term includes beam-type irradiators.

Panoramic Wet-Source-Storage Irradiator- 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.

Pool Irradiator- any irradiator at which the sources are stored or used in a pool of water including panoramic wet-source-storage irradiators and underwater irradiators.

Product Conveyor System- a system for moving the product to be irradiated to, from, and within the area where irradiation takes place.

Radiation Room- a shielded room in which irradiations take place. Underwater irradiators do not have radiation rooms.

Sealed Source- 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.

Seismic Area- 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.

Underwater Irradiator- 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.
