Section 180-8-008 - ADDITIONAL REQUIREMENTS FOR CLOSED-BEAM RADIATION GENERATING DEVICES In addition to the requirements of section 003 through 007, the following requirements apply to all closed-beam radiation generating devices:
008.01SYSTEM ENCLOSURE. The radiation source, sample or object, detector, and analyzing crystal, if used, must be enclosed in a chamber or coupled chambers that cannot be entered by any part of the body during normal operation.008.02RADIATION EMISSION LIMIT. The radiation emission for all closed beam radiation generating devices must not exceed a dose rate of 0.005 milliSievert ( 0.5 millirem) in one hour at five centimeters outside any accessible surface.008.03SECURITY SCREENING UNITS. Security screening units must be provided with means to ensure operator presence at the control area in a position which allows surveillance of the openings and doors during generation of x-radiation. (A) During an exposure or preset succession of exposures of one-half second or greater duration, the means provided must enable the operator to terminate the exposure or preset succession of exposures at any time.(B) During an exposure or preset succession of exposures of less than one-half second duration, the means provided may allow completion of the exposure in progress but must enable the operator to prevent additional exposures.180 Neb.
