Out-Of-State Radiation Machines

Out-Of-State Radiation Machines. 1. Whenever any radiation machine is to be brought into the State, for any temporary use, the person proposing to bring such machine into the State shall give written notice to the Agency at least 3 days before such machine is to be used in the State. The notice shall include: a. the type of radiation machine; b. the nature, duration, and scope of use; c. the exact location(s) where the radiation machine is to be used; and d. states in which this machine is registered. 2 In the case of diagnostic x-ray systems which contain certified components, a copy of the assembler's report prepared in compliance with requirements of the Federal diagnostic x-ray standard (21 CFR 1020.30(d)) shall be submitted to the Agency within 15 days following completion of the assembly. Such report shall suffice in lieu of any other report by the assembler. 2. If, for a specific case, the 3 day period would impose an undue hardship on the person, upon application to the Agency, permission to proceed sooner may be granted. 3. The person referred to in 1.2.13(1) shall: a. comply with all applicable regulations of the Agency; b. supply the Agency with such other information as the Agency may reasonably request; and c. not operate within the State on a temporary basis in excess of 180 calendar days per year. Source: MS Code Ann. §45-14-3 APPENDIX A Information On Radiation Shielding Required For Plan Reviews In order for the Agency to provide an evaluation, technical advice, and official approval on shielding requirements for a radiation installation, the following information must be submitted. I. The plans should show, as a minimum, the following: a. The normal location of the x-ray system's radiation port; the port's travel and traverse limits; general direction(s) of the useful beam; locations of any windows and doors; the location of the operator's booth; and the location of the x-ray control panel. b. The structural composition and thickness or lead equivalent of all walls, doors, partitions, floor, and ceiling of the room(s) concerned. c. The dimensions of the room(s) concerned. d. The type of occupancy of all adjacent areas inclusive of space above and below the room(s) concerned. If there is an exterior wall, show distance to the closest area(s) where it is likely that individuals may be present. e. The make and model of the x-ray equipment and the maximum technique factors, and the energy waveform (single phase, three phase, etc.). f. The type of examination(s) or treatment(s) which will be performed with the equipment. II. Information on the anticipated workload of the x-ray system(s) in mA-minutes per week. III. A report showing all basic assumptions used in the development of the shielding specifications. APPENDIX B Design Requirements For An Operator’s Booth I. Space Requirements: a. The operator shall be allotted not less than 7.5 square feet (0.70m²) of unobstructed floor space in the booth. b.The operator's booth may be any geometric configuration with no dimension of less than 2 feet (0.61 m). c. The space shall be allotted excluding any encumbrance by the x-ray control panel, such as overhang, cables, or other similar encroachments. d.The booth shall be located or constructed such that unattenuated direct scatter radiation originating from the examination table or at the wall cassette holder will not reach the operator's position in the booth. II. Structural Requirements: a. The booth walls shall be permanently fixed barriers of at least 7 feet (2.1 m) high. b.When a door or movable panel is used as an integral part of the booth structure, it must have an interlock which will prevent an exposure when the door or panel is not closed. c. Shielding shall be provided to meet the requirements of Subchapter 4 of these regulations. III. X-Ray Exposure Control Placement: a. The x-ray exposure control for the system shall be fixed within the booth and: b.Shall be at least 40 inches (1.0 m) from any open edge of the booth wall which is nearest to the examining table. c. Shall allow the operator to use the majority of the available viewing windows. IV. Viewing System Requirements: a. Each booth shall have at least one viewing device which will: i. Be so placed that the operator can view the patient during any exposure, and ii. Be so placed that the operator can have full view of any occupant of the room and should be so placed that the operator can view any entry into the room. If any door which allows access to the room cannot be seen from the booth, then outside that door there shall be an "x-ray on" warning sign that will be lighted anytime the rotor of the x-ray tube is activated. Alternatively, an interlock must be present such that exposures are prevented unless the door is closed. b.When the viewing system is a window, the following requirements also apply: i. It shall have a viewing area of at least 1 square foot (0.093 m2). ii. Regardless of size or shape, at least 1 square foot of the window area must be centered no less than 2 feet (0.61 m) from the open edge of the booth and no less than 5 feet (1.52 m) from the floor. iii. The window shall have at least the same lead equivalence as that required in the booth's wall in which it is mounted. c. When the viewing system is by mirrors, the mirror(s) shall be so located as to accomplish the general requirements of Appendix B.IV(A). d.When the viewing system is by electronic means: i. The camera shall be so located as to accomplish the general requirements of Appendix B.IV(A), and ii. There shall be an alternate viewing system as a backup for the primary system Subchapter 3 Licensing of Radioactive Material
