Section 61-64.VII.RHB 7.7 - Area Requirements for all Analytical X-ray Equipment7.7.1 Radiation Levels. The local components of an analytical x-ray system shall be located and arranged and shall include sufficient shielding or have access control such that no radiation in any area surrounding the local component group could result in a dose to an individual present therein in excess of the dose limits given in RHB 3.4. These levels shall be met at any specified tube rating.7.7.2 Surveys, Tests, and Inspections. Radiation surveys, as required by RHB 1.4, of all analytical x-ray systems to show compliance with RHB 7.7.1 shall be performed and records kept and available for review: 7.7.2.1 Upon installation of the equipment and at least once every twelve (12) months thereafter;7.7.2.2 Following any change in the initial arrangement, number, or type of local components in the system;7.7.2.3 Following any change in operating parameters;7.7.2.4 Following any maintenance requiring the disassembly or removal of a local component of the system;7.7.2.5 During the performance of maintenance and alignment procedures if the procedures require the presence of a primary x-ray beam when any local component in the system is disassembled or removed;7.7.2.6 Any time a visual inspection of the local components in the system reveals an abnormal condition; and7.7.2.7 Whenever a monitoring device shows a significant increase over the previous monitoring period or the readings are approaching the radiation dose limits specified in RHB 3.4.7.7.3 Radiation survey measurements shall not be required if a registrant can demonstrate compliance with RHB 7.7.1. For enclosed beam analytical x-ray equipment, an area monitor or monitors may be used in place of an annual radiation survey. The area monitor shall be placed on the unit and changed on at least a quarterly basis. The results shall be documented and available for review. If an area monitor result shows a substantial increase over previous results, perform a documented investigation including a radiation area survey.7.7.4 Tests and inspections of all safety devices shall be performed at least yearly to ensure their proper operation.7.7.5 All surveys, tests, and inspections shall be documented and records shall be maintained and available for Departmental review in accordance with RHB 1.10.2.4.S.C.
