DHS 157.73 Radiation safety requirements. DHS 157.73(1)(a)
(a) A sealed source installed in an irradiator shall meet all of the following requirements:
DHS 157.73(1)(a)3.
3. Use radioactive material that is as nondispersible and insoluble as practical if the source is used in a wet-source-storage or wet-source-change irradiator.
DHS 157.73(1)(a)4.
4. Be encapsulated in a material resistant to general corrosion and to localized corrosion such as 316L stainless steel or other material with equivalent resistance if the sources are for use in irradiator pools.
DHS 157.73(1)(a)5.
5. In prototype testing of the sealed source, be leak tested and found leak-free after each of the tests in par.
(b).
DHS 157.73(1)(b)
(b) A sealed source used in an irradiator shall be subjected to all of the following tests prior to use:
DHS 157.73(1)(b)1.
1. `Temperature.' The test source shall be held at -40
°C for 20 minutes, 600
°C for one hour, and then be immediately subjected to thermal shock test with a temperature drop from 600
°C to 20
°C within 15 seconds.
DHS 157.73(1)(b)2.
2. `Pressure.' The test source shall be twice subjected for at least 5 minutes to an absolute external pressure of 2 million newtons per square meter.
DHS 157.73(1)(b)3.
3. `Impact.' A 2 kilogram steel weight, 2.5 centimeters in diameter, shall be dropped from a height of one meter on to the test source.
DHS 157.73(1)(b)4.
4. `Vibration.' The test source shall be subjected 3 times for 10 minutes each to vibrations sweeping from 25 hertz to 500 hertz with a peak amplitude of 5 times the acceleration of gravity. In addition, each test source shall be vibrated for 30 minutes at each resonant frequency found.
DHS 157.73(1)(b)5.
5. `Puncture.' A 50 gram weight and pin, 0.3 centimeter pin diameter, shall be dropped from a height of one meter on to the test source.
DHS 157.73(1)(b)6.
6. `Bend.' If the length of the source is more than 15 times larger than the minimum cross-sectional dimension, the test source shall be subjected to a force of 2000 newtons at its center equidistant from 2 support cylinders, the distance between which is 10 times the minimum cross-sectional dimension of the source.
DHS 157.73(2)(a)(a) Each entrance to a radiation room at a panoramic irradiator shall have a door or other physical barrier to prevent inadvertent entry of personnel when the sources are not in the shielded position. Product conveyor systems may serve as barriers as long as they reliably and consistently function as a barrier. It shall be impossible to move the sources out of their shielded position if the door or barrier is open. Opening the door or barrier while the sources are exposed shall cause the sources to return promptly to the shielded position. The personnel entrance door or barrier shall have a lock that is operated by the same key used to move the sources. The control panel lock shall be designed so that the key cannot be removed unless the sources have been returned to the shielded position. The doors and barriers may not prevent any person in the radiation room from leaving.
DHS 157.73(2)(b)
(b) Each entrance to a radiation room at a panoramic irradiator shall have an independent backup access control to detect personnel entry while the sources are exposed. Detection of entry while the sources are exposed shall cause the sources to return to their fully shielded position and shall activate a visible and audible alarm to make the person entering the room aware of the hazard. The alarm shall also alert at least one other person who is on-site of the entry. The person alerted shall be trained on how to respond to the alarm and prepared to promptly render or summon assistance.
DHS 157.73(2)(c)
(c) A radiation monitor shall be provided to detect the presence of high radiation levels in the radiation room of a panoramic irradiator before personnel entry. The monitor shall be integrated with personnel access door locks to prevent room access when radiation levels are high. Attempted personnel entry while the monitor measures high radiation levels shall activate the alarm described in par.
(b). The monitor may be located in the entrance, normally referred to as the maze, but not in the direct radiation beam.
DHS 157.73(2)(d)
(d) Before the sources move from their shielded position in a panoramic irradiator, the source control shall automatically activate conspicuous visible and audible alarms to alert people in the radiation room that the sources will be moved from their shielded position. The alarms shall give persons enough time to leave the room before the sources leave the shielded position.
DHS 157.73(2)(e)
(e) Each radiation room of a panoramic irradiator shall have a clearly visible and readily accessible control that allows a person in the room to make the sources return to their fully shielded position.
DHS 157.73(2)(f)
(f) Each radiation room of a panoramic irradiator shall contain a control that prevents the sources from moving from the shielded position unless the control has been activated and the door or barrier to the radiation room has been closed within a preset time after activation of the control.
DHS 157.73(2)(g)
(g) Each entrance to the radiation room of a panoramic irradiator and each entrance to the area within the personnel access barrier of an underwater irradiator shall have a sign bearing the radiation symbol and the words, “Caution (or danger), radioactive material." A panoramic irradiator shall have a sign stating “Grave (or Extreme) danger, very high radiation area," but the sign may be removed, covered or otherwise made inoperative when the sources are fully shielded.
DHS 157.73(2)(h)
(h) If the radiation room of a panoramic irradiator has roof plugs or movable shielding, no person may operate the irradiator unless the shielding is in its proper location. The requirement may be met by interlocks that prevent operation if shielding is not placed properly or by an operating procedure requiring inspection of shielding before operating.
DHS 157.73(2)(i)
(i) An underwater irradiator shall have a personnel access barrier around the pool that shall be locked to prevent access when the irradiator is not attended. Only operators or facility management may have access to keys that operate the personnel access barrier. There shall be an intrusion alarm to detect unauthorized entry when the personnel access barrier is locked. Activation of the intrusion alarm shall alert a person who is not necessarily on-site but who is prepared to respond or summon assistance.
DHS 157.73(3)(a)(a) The radiation dose rate in areas that are normally occupied during operation of a panoramic irradiator may not exceed 0.02 millisievert (2 mrem) per hour at any location 30 centimeters or more from the wall of the room when the sources are exposed. The dose rate shall be averaged over an area not to exceed 100 square centimeters having no linear dimension greater than 20 centimeters. Any area where the radiation dose rate exceeds 0.02 millisievert (2 mrem) per hour shall be locked, roped off or posted.
DHS 157.73(3)(b)
(b) The radiation dose at 30 centimeters over the edge of the pool of a pool irradiator may not exceed 0.02 millisievert (2 mrem) per hour when the sources are in the fully shielded position.
DHS 157.73(3)(c)
(c) The radiation dose rate at one meter from the shield of a dry-source-storage panoramic irradiator when the source is shielded may not exceed 0.02 millisievert (2 mrem) per hour and at 5 centimeters from the shield may not exceed 0.2 millisievert (20 mrem) per hour.
DHS 157.73(4)(a)(a) The radiation room of a panoramic irradiator shall have heat and smoke detectors. The detectors shall activate an audible alarm. The alarm shall be capable of alerting a person who is prepared to summon assistance promptly. The sources shall automatically become fully shielded if a fire is detected.
