DHS 157.73(11)(f)(f) Source rack. For a panoramic irradiator, a licensee shall test the movement of the source racks for proper operation prior to source loading. The testing shall include source rack lowering due to simulated loss of power. For all irradiators with a product conveyor system, a licensee shall observe and test the operation of the conveyor system to assure that the requirements in sub. (8) are met for protection of the source rack and the mechanism that moves the rack. The testing shall include tests of any limit switches and interlocks used to protect the source rack and mechanism that moves that rack from moving product carriers.

DHS 157.73(11)(g)(g) Access control. For a panoramic irradiator, a licensee shall test the completed access control system to assure that the control system functions as designed and that all alarms, controls, and interlocks work properly.

DHS 157.73(11)(h)(h) Fire protection. For a panoramic irradiator, a licensee shall test the ability of the heat and smoke detectors to detect a fire, to activate alarms, and to cause the source rack to automatically become fully shielded. A licensee shall test the operability of the fire extinguishing system.

DHS 157.73(11)(i)(i) Source return. For a panoramic irradiator, the licensee shall demonstrate that the source racks may be returned to their fully shielded positions without power.

DHS 157.73(11)(j)(j) Computer systems. For a panoramic irradiator that uses a computer system to control the access control system, a licensee shall verify that the access control system will operate properly if power is lost and shall verify that the computer has security features that prevent an irradiator operator from commanding the computer to override the access control system when the system is required to be operable.

DHS 157.73(11)(k)(k) Wiring. For a panoramic irradiator, a licensee shall verify that the electrical wiring and electrical equipment that were installed meet the design specifications.

DHS 157.73(12)(a)(a) Before a person may act as an irradiator operator without a supervisor present, the person shall be instructed in all the following:

DHS 157.73(12)(a)1.1. The fundamentals of radiation protection applied to irradiators. The fundamentals shall include the differences between external radiation and radioactive contamination, units of radiation dose, dose limits, why large radiation doses must be avoided, how shielding and access controls prevent large doses, how an irradiator is designed to prevent contamination, the proper use of survey meters and personnel dosimeters, other radiation safety features of an irradiator and the basic function of the irradiator.

DHS 157.73(12)(b)(b) Before a person may act as an irradiator operator without a supervisor present, the person shall pass a written test on the instruction received consisting primarily of questions based on the licensee’s operating and emergency procedures that the person is responsible for performing and other operations necessary to safely operate the irradiator without supervision.

DHS 157.73(12)(c)(c) Before a person may act as an irradiator operator without a supervisor present, the person shall have received on-the-job training or simulator training in the use of the irradiator as described in the license application. The person shall also demonstrate the ability to perform those portions of the operating and emergency procedures that he or she is to perform.

DHS 157.73(12)(d)(d) A licensee shall conduct safety reviews for irradiator operators at least annually, at intervals not to exceed 13 months. At the review, the licensee shall give each operator a written test on the information presented during annual safety training. Each safety review shall include, to the extent appropriate, all of the following:

DHS 157.73(12)(e)(e) A licensee shall evaluate the safety performance of each irradiator operator at least annually, at intervals not to exceed 13 months, to ensure that regulations, license conditions and operating, safety and emergency procedures are followed. The licensee shall discuss the results of the evaluation with the operator and shall instruct the operator on how to correct any mistakes or deficiencies observed.

DHS 157.73(12)(f)(f) Persons who will be permitted unescorted access to the radiation room of the irradiator or the area around the pool of an underwater irradiator, but who have not received the training required for operators and the radiation safety officer, shall be instructed and tested in any precautions they should take to avoid radiation exposure, any procedures or parts of procedures listed in sub. (13) that they are expected to perform or comply with and their proper response to alarms required in this subchapter. Tests may be oral.

DHS 157.73(12)(g)(g) Persons who must be prepared to respond to alarms required by subs. (2) (b) and (i), (4) (a), (5) (a) and (b), and (16) (b) shall be trained and tested on how to respond. Each person shall be retested at least annually, at intervals not to exceed 13 months. Tests may be oral.
