§ 227a.40. Safety device.
(a) Documentation. The registrant shall document its justification of the use of an open-beam instead of closed-beam radiation-producing device.
(b) Open-beam considerations. If the registrant needs to use an open-beam radiation-producing device, the registrant shall consider a safety device which minimizes the chance of entry of any portion of the operator’s body into the path of the primary beam or which causes the primary beam to be shut off upon entry into its path.
(c) Records. If the registrant’s use of an open-beam radiation-producing device does not permit the use of a safety device to minimize the chance of direct body exposure, the registrant shall maintain a written record of the justification required in subsection (a) and a description of the various safety devices that have been evaluated and reasons the devices cannot be used. These records shall be available onsite for inspection as long as this method is used, plus an additional 5 years.
(d) Alternative methods. If the registrant’s use of the open-beam radiation-producing device does not permit the use of a safety device to minimize the chance of direct body exposure, the registrant shall use alternative methods, such as policies and procedures, to minimize the possibility of unnecessary exposure. The registrant shall document the alternative methods used. The documentation must include information about the absence of safety devices. This documentation shall be available for inspection as long as the methods are used plus an additional 5 years.
(e) Compliance. For a portable open-beam radiation-producing device without a safety device described under subsection (b) that is manufactured to be used or potentially used as a handheld device, the safety device requirements under subsections (b)—(d) shall be met by complying with § 227a.50 (relating to handheld radiation-producing devices) prior to use.
