The purpose of this requirement is to ensure machine operators and members of the general public are not unnecessarily exposed to radiation and are kept below their legal dose limits. Shielding requirements will be determined by this potential exposure to humans and must take into consideration occupancy factors, distance, work load, energy, and direction of the primary beam, and other related factors. Typical chiropractic x-ray machine installations make use of a vertical bucky mounted on an outside wall. For this type of x-ray machine installation, the following guidance applies: 1. No shielding is necessary for outside walls. 2. Shielding is necessary for inside walls when a. the primary beam will be directed toward it without a beam block to intercept, or b. normally occupied spaces are within eight (8) feet of the source of scatter. A protected position is required for the operator. New facilities (after Jan 95) requires a non-movable barrier for the operator. Thus, one-sixteenth (1/16) inch lead equivalent shielding would be required to a height of seven (7) feet for the operators protected position and behind any inside wall mounted vertical bucky to block the primary beam. No additional shielding is normally required on the other walls except in special cases, such as when an office worker is in close proximity to the x-ray room or a wall of the x-ray room is shared with another tenant. Shielding plan review and/or approval is not required by this office unless the energies used exceed 200 kVp. High volume offices (greater than 1000 mA minutes per week) or offices with fluoroscopic or special function machines should consider having their shielding planned by a licensed medical physicist. The Bureau of Radiation Control will inspect each facility that uses a radiation machine and require adequate shielding to protect operators and the public.
