420.10的介绍

确保产生辐射的设备正常运行, 被充分屏蔽, 有适当的联锁和安全功能, and is routinely monitored for radiation leakage and proper operation of safety features are key components of any radiation safety program.

420.20产生辐射设备操作规程

Specific operating and emergency procedures including testing of safety features and interlocks shall be posted in the radiation-producing equipment area, and all personnel shall be familiar with and comply with these instructions. A copy of the Certificate of Registration issued by the Idaho Department of 健康 & Welfare must be posted on or immediately adjacent to each radiation-producing machine.

420.30产生辐射设备使用日志

All users shall maintain a separate log showing the use of radiation-producing equipment in possession, 包括设备的使用日期, 该日期的目的和人员. This log will be kept in a clear and concise format that can easily be understood by the radiation safety officer or other inspector.

420.40调查频率

Frequency and type of surveys will be according to those approved by the 辐射安全 委员会 at time of authorization, or to the applicable section(s) of the Idaho Radiation Control Regulations for the type of radiation-producing equipment in question. 必须对所有新装置进行检查, and after any significant service to the equipment (replacement of x-ray tube, 波束过滤变化, 等.).

420.50个泄漏

If leakage is found in excess of the limits specified in the applicable section(s) of the Idaho Radiation Control regulations for the type of radiation-producing equipment in question, the equipment must be made inoperable and the radiation safety officer or designee notified immediately. Such equipment shall not be used until the problems causing the leakage are corrected, and further surveys confirm leakage is below the allowable limits.

420.60 Radiation-Producing Equipment Inspection, Servicing and Maintenance

All users shall follow any equipment control measures specified by the manufacturer and/or 辐射安全 委员会. The authorized user shall also comply with all other applicable sections of the Idaho Radiation Control Regulations for the type of radiation-producing equipment in question. 所有的调整, maintenance and servicing necessary for safe use of the equipment must be performed on a regular basis as recommended by the manufacturer, and records shall be kept by the authorized user for review by the radiation safety officer or other inspector. Any changes to the equipment set-up which could affect the potential radiation hazard must be approved by the radiation safety officer or designee. Certain aspects of radiation-producing equipment must be monitored frequently:

1. 操作规范 -辐射束的方向, 电压, 当前的, time, permanent filter and maximum aperture shall be in agreement with the manufacturer's recommendations for the specific application.
2. 百叶窗和锁 - Shutter mechanisms and interlocking devices shall be inspected by the radiation safety officer or designee at least every six months for proper operation.
3. 警告装置及辐射监测设备 - All visual and audible warning devices and monitoring equipment shall be inspected by the radiation safety officer or designee every six months for proper operation.
4. 测量计:
1. The use of a survey meter is appropriate for x-ray emitting equipment.
2. All survey meters and detectors must be approved by the radiation safety officer.
3. 每次调查前, 电池必须测试, and a check standard must be used to establish that the survey meter is operable and properly detecting the radiation field.
4. The area surveyed must be large enough to adequately cover the area of possible leakage.
5. The results of leakage surveys can be recorded on the Contamination Survey Form RSM-3 or the equivalent information can be recorded in a user's log book. 背景辐射水平也必须记录下来.
6. 测量仪表和探测器应每年校准一次. A certificate of calibration will be required as verification that the instrument has been properly calibrated.
7. Survey meters and detectors can be calibrated by returning the meter and detector to the manufacturer or other commercial vendor providing calibration services. 当用户的仪表和检测器被校准时, a survey meter and detector may be borrowed from the radiation safety officer.
