This guide does not replace the regulations. Changing from routine to exception-based gonadal shielding during pediatric X-ray studies will be challenging due to expectations of those who place shields and those who get shields. (a) Every manufacturer of an electronic product to which a standard under this subchapter is applicable shall set forth the information specified in paragraphs (a)(1) and (2) of this section. Ray-Bar Engineering is the foremost leader in the design and manufacturing of x-ray protection and radiation shielding materials. The performance standard [21 CFR 1020.40(a)] does not apply to: Other categories of x-ray systems are defined below. Generally, manufacturers of cabinet x-ray systems are subject to the reporting requirements. The general performance standard for electronic products [21 CFR Part 1010] applies to cabinet x-ray systems because the specific performance standard for cabinet x-ray systems [21 CFR 1020.40] applies. Use beam-restrictive devices and patient-shielding techniques to minimize . The most commonly used shielding material against ionising radiation is lead. The designation must provide that it will remain in effect until withdrawn or replaced by the manufacturer and shall bear a declaration of acceptance duly signed by the designated agent. An x-ray tube used within a shielded part of a building, or x-ray equipment which may temporarily or occasionally incorporate portable shielding is not considered a cabinet x-ray system. 360hh-360ss]. Ion chambers are usually appropriate instruments for making quantitative measurements of radiation emission from cabinet x-ray systems. Manufacturers may also include information describing exposure hazards and radiation safety precautions appropriate for patients and other individuals present in the area during examination (e.g., a person holding a child or other personnel assisting with procedures). 13, NCRP Recommendations for Ending Routine Gonadal Shielding During Abdominal and Pelvic Radiography. 552) (FOIA). It does not create or confer any rights for or on any person and does not operate to bind FDA or the public.

X-ray and radiotherapy equipment; Sources. Test their products to assure compliance with the performance standard [21 CFR 1010.2(c)]; this test should be an element of a quality control and testing program that is in accordance with good manufacturing practices. Because the shielding surrounds the volume exposed to x-ray and the shielding is an inherent part of the system, cabinet x-ray systems are sometimes referred to as closed x-ray systems. [21 CFR 1020.40(c)(6)(iii)] Two independent means which indicate when and only when xrays are being generated, unless the x-ray generation period is less than one-half second, in which case the indicators shall be activated for one-half second, and which are discernible from any point at which initiation of x-ray generation is possible. Some state programs do not allow the use of hand-held x-ray equipment. The intent of this guidance is to advise manufacturers and FDA staff about safety procedures and recommendations that should be provided to the end user to promote safe use of hand-held x-ray equipment. These model numbers should be reported in quarterly updates to the annual report. Comments may not be acted upon by the Agency until the document is next revised or updated. Primary beam [21 CFR 1020.40(b)(10)] means the x radiation emitted directly from the target and passing through the window of the x-ray tube. Certification of compliance with a foreign radiation safety standard can not be substituted for certification of compliance with the U.S. performance standard. NCRP Statement No. [21 CFR 1002.20(b)] ARO reports shall contain all of the following information where known to the manufacturer: (1) The nature of the accidental radiation occurrence; (2) The location at which the accidental radiation occurrence occurred; (3) The manufacturer, type, and model number of the electronic product or products involved; (4) The circumstances surrounding the accidental radiation occurrence, including causes; (5) The number of persons involved, adversely affected, or exposed during the accidental radiation occurrence, the nature and magnitude of their exposure and/or injuries and, if requested by the Director, Center for Devices and Radiological Health, the names of the persons involved; (6) The actions, if any, which may have been taken by the manufacturer, to control, correct, or eliminate the causes and to prevent reoccurrence; and. X-ray on time can be limited by physical system properties or interlocks. Examples include, but are not limited to, radiation therapy products that use accelerators and veterinary x-ray systems. Aperture [21 CFR 1020.40(b)(2)] means any opening in the outside surface of the cabinet, other than a port, which remains open during generation of x radiation. The manufacturers corrective actions must be made in accordance with a plan approved by FDA [21 CFR 1004.6]. 13, the implantation guide and the trifold online. (iii) Audible and visible warning signals within the cabinet which are actuated for at least 10 seconds immediately prior to the first initiation of x-ray generation after closing any door designed to admit humans. Manufacturers of cabinet x-ray system products must certify their products comply with all the applicable requirements of the performance standard [21 CFR 1020.40]. [21 CFR 1020.40(c)(4)(iv)] Failure of any single component of the cabinet x-ray system shall not cause failure of more than one required safety interlock. The federal performance standard for diagnostic x-ray systems and their major components did not anticipate hand-held x-ray systems at the time it was written. ], The primary door interlock should be of conventional design. Many reputable sources are considered for ARRT's requirements of education, ethics, and examination. People frequently ask us what, if any, requirements have been set for X-ray shielding in rooms where C-arms are in use. You may find many of the following definitions in 21 CFR 1000.3 or 1020.40(b) (we have provided the specific citations). Failure of any single component of the cabinet x-ray system shall not cause failure of both the audible and visible warning signals. A system with a straight tunnel less than 36 inches from any port to the primary beam should have some means other than distance to make the primary beam difficult to reach. Included are all x-ray systems designed primarily for the inspection of carry-on baggage at airline, railroad, and bus terminals, and in similar facilities. 10903 New Hampshire Avenue Cabinet x-ray systems are subject to the most extensive requirements because cabinet x-ray systems are subject to a specific performance standard [21 CFR 1020.40].

The contents and criteria for an application for exemption and its approval are found in 21 CFR 1010.5. Introduction. The phrase, facilities similar to airline, railroad, and bus terminals, includes any place where members of the public walk up to an x-ray system for the purpose of security screening of their carried belongings. Diagnostic x-ray equipment manufactured for the US market must meet the performance requirements described in Title 21 of the Code of Federal Regulations, sections 1020.30 through 1020.33, which require manufacturers to provide users with operational and safety information as well as to meet standards for equipment performance.1, Internationally, radiation safety standards are provided by the International Electrotechnical Commission (IEC) in its collateral standard 60601-1-3.2 Voluntary guidelines, particularly relevant to handheld equipment, have been provided by the National Council on Radiation Protection and Measurement (NCRP) for radiation protection in dentistry.3 Many states regulate the use of x-ray equipment under their own regulations based on the Suggested State Regulations for the Control of Radiation, published by the Conference of Radiation Control Program Directors (CRCPD).4. For the purposes of paragraph (c)(4)(i) of this section, inflexible hardware rigidly affixed to the door shall be considered part of the door. 263h(d)) and this section. In addition to the performance standard [21 CFR 1020.40], manufacturers of cabinet x-ray systems sold in the U.S. must comply with 21 CFR Parts 1000, 1002, 1003, 1004, 1005, and 1010. This guidance has been endorsed by numerous organizations, including the American College of Radiology. In certain cases, when applied for, exemptions from the performance standard may be approved by the Director, Center for Devices and Radiological Health, if it is determined that the cabinet x-ray system is intended for use by departments or agencies of the United States and the system meets the following criteria: Applications for exemptions should include an original and two copies and should be addressed to: You should not include information classified for reasons of national security in your application. All other indicators shall be legibly labeled X-RAY ON. The required shield thickness depends on three things: 1. Industrial X-Ray and Particulate Radiation Systems You should not assume that because a GM meters readout scale is scribed in exposure rate units that the meter will accurately measure that quantity. However, if the barrier must be moved for the material being irradiated to be placed in or removed from the cabinet as part of routine operations, then the barrier is a door even if tools are needed. Unless an exemption from notification [21 CFR 1003.30 and 1003.31] was requested and granted, the manufacturer shall also furnish notification, following the requirements of 21 CFR 1003.21, with reasonable promptness to the following persons: When FDA determines that a defect or failure to comply has occurred, FDA will notify the manufacturer in accordance with 21 CFR 1003.11.
