CHAPTER 289RADIATION CONTROL
SUBCHAPTER FLICENSE REGULATIONS
RULE §289.258Licensing and Radiation Safety Requirements for Irradiators

(a) Purpose. This section contains requirements for the issuance of a license authorizing the use of sealed sources containing radioactive material used in irradiating objects or materials using gamma radiation. This section also contains radiation safety requirements for operating irradiators.

(b) Scope.

  (1) In addition to the requirements of this section, all licensees, unless otherwise specified, are subject to the requirements of:

    (A) §289.201 of this chapter (relating to General Provisions for Radioactive Material);

    (B) §289.202 of this chapter (relating to Standards for Protection Against Radiation from Radioactive Materials);

    (C) §289.203 of this chapter (relating to Notices, Instructions, and Reports to Workers; Inspections);

    (D) §289.204 of this chapter (relating to Fees for Certificates of Registration, Radioactive Material Licenses, Emergency Planning and Implementation, and Other Regulatory Services);

    (E) §289.205 of this chapter (relating to Hearing and Enforcement Procedures);

    (F) §289.252 of this subchapter (relating to Licensing of Radioactive Material); and

    (G) §289.257 of this subchapter (relating to Packaging and Transportation of Radioactive Material).

  (2) Nothing in this section relieves the licensee from complying with other applicable federal, state, and local regulations governing the siting, zoning, land use, and building code requirements for industrial facilities.

  (3) The requirements in this section apply to panoramic irradiators having either dry or wet storage of radioactive sealed sources and to underwater irradiators in which both the source and the product being irradiated are under water. Irradiators whose dose rates are greater than 500 rads (5 grays) per hour at 1 meter (m) from the radioactive sealed sources in air or in water, as applicable for the irradiator type, are covered by this section.

  (4) The requirements in this section do not apply to self-contained, dry-source-storage irradiators (those in which both the source and the area subject to irradiation are contained within a device and are not accessible by personnel), medical radiology or teletherapy, radiography (the irradiation of materials for non-destructive testing purposes), gauging, or open-field (agricultural) irradiations.

(c) Definitions. The following words and terms when used in this section have the following meanings unless the context clearly indicates otherwise.

  (1) Annually--At intervals not greater than 390 days.

  (2) Doubly encapsulated sealed source--A sealed source in which the radioactive material is sealed within a capsule and that capsule is sealed within another capsule.

  (3) Category I self-contained, dry-source irradiator--An irradiator in which the sealed source is completely contained in a dry container constructed of solid materials and shielded at all times, and in which human access to the sealed source and the volume undergoing irradiation is not physically possible in its designed configuration.

  (4) Irradiator--A facility using radioactive sealed sources for the irradiation of objects or materials and in which radiation dose rates are greater than 500 rads (5 grays) per hour exist at 1 m 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 not accessible to personnel.

  (5) Irradiator operator--An individual who successfully completed the training and testing described in subsection (s) of this section and is authorized by the terms of the license to operate the irradiator without the presence of a supervisor who completed the requirements of subsection (s)(1) - (3) of this section.

  (6) Onsite--A physical presence within the building housing the irradiator or on property controlled by the licensee contiguous with the building housing the irradiator.

  (7) 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.

  (8) Panoramic irradiator--An irradiator in which the irradiations are done in air in areas potentially accessible to personnel. The term includes beam-type irradiators.

  (9) 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.

  (10) Pool irradiator--Any irradiator in which the sources are stored or used in a pool of water, including panoramic wet-source-storage irradiators and underwater irradiators.

  (11) Product conveyor system--A system for moving the product to be irradiated to, from, and within the area where irradiation takes place.

  (12) Radiation room--A shielded room in which irradiations take place. Underwater irradiators do not have radiation rooms.

  (13) Seismic area--Any area where the probability of 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 United States Geological Survey.

  (14) 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.

(d) Application for a specific license. Applications for specific licenses must be filed as specified in §289.252(d) of this subchapter.

(e) Specific licenses for irradiators.

  (1) The department approves an application for a specific license for the use of licensed material in an irradiator if the applicant meets the requirements contained in this section.

  (2) The applicant must satisfy the general requirements specified in §289.252 of this subchapter and the requirements contained in this section.

  (3) The application must describe the training provided to irradiator operators including:

    (A) classroom training;

    (B) on-the-job or simulator training;

    (C) safety reviews;

    (D) means employed by the applicant to test each operator's understanding of the department's rules and licensing requirements and the irradiator operating, safety, and emergency procedures; and

    (E) minimum training and experience of personnel providing training.

  (4) The application must include a copy of the written operating, safety, and emergency procedures as outlined in subsection (t) of this section describing the radiation safety aspects of the procedures.

  (5) The application must describe the organizational structure for managing the irradiator, specifically the radiation safety responsibilities and authorities of the radiation safety officer (RSO) and those management personnel having radiation safety responsibilities or authorities. In particular, the application must specify who, within the management structure, has the authority to stop unsafe operations. The application must also describe the training and experience required for the position of RSO.

  (6) The application must include a description of the access control systems required by subsection (i) of this section, the radiation monitors required by subsection (l) of this section, the method of detecting leaking sources required by subsection (w) of this section, including the sensitivity of the method, and a diagram of the facility showing the locations of all required interlocks and radiation monitors.

  (7) If the applicant intends to perform and analyze leak tests of dry-source-storage sealed sources, the applicant must establish procedures for leak testing and submit a description of these procedures to the department. The description must include at least:

    (A) the instruments to be used;

    (B) the methods of performing the analysis; and

    (C) the pertinent experience of the individual analyzing the samples.

  (8) If licensee personnel are to load or unload sources, the applicant must describe the qualifications and training of the personnel and the procedures used. If the applicant intends to contract for source loading or unloading at its facility, the loading or unloading must be done by a person specifically authorized by the department, the United States Nuclear Regulatory Commission (NRC), or an agreement state to load or unload irradiator sources.
