§ 227a.14. Generating cabinet or high voltage source radiation emission limits.
Each X-ray generator or high-voltage source must be supplied with a protective cabinet which limits leakage radiation to 0.5 mrem (5.0 µSv) per hour at 5 centimeters measured at the nearest accessible surface. For closed-beam radiation-producing devices, this requirement may be met by complying with § 227a.33 (relating to radiation emission limit). For a radiation-producing device in a shielded room with the high-voltage generator also inside the shielded room, this limit may be met by measuring from any accessible surface outside the room housing the radiation-producing device. For hand-held, open-beam radiation-producing devices, this requirement may be met by complying with the limits under § 227a.50(3) (relating to handheld radiation-producing devices).
