(b) The device must automatically secure the source assembly when it is cranked back into the fully shielded position within the device.  The securing system may only be released by means of a deliberate operation on the exposure device.

(c) The outlet fittings, lock box, and drive cable fitting on each radiographic exposure device must be equipped with safety plugs or covers which must be installed during storage and transportation to protect the source assembly from water, mud, sand, or other foreign matter.

(d)(i) Each sealed source or source assembly must have attached to it or engraved on it, a durable, legible, visible label with the words: "DANGER--RADIOACTIVE."

(ii) The label may not interfere with the safe operation of the exposure device or associated equipment.

(e) The guide tube must ((have passed the crushing tests for the control tube as specified in ANSI N432 and)) be able to withstand a crushing test that closely approximates the crushing forces that are likely to be encountered during use, and be able to withstand a kinking resistance test that closely approximates the kinking forces likely to be encountered during use.

(((e))) (f) Guide tubes ((or exposure heads connected directly to the device)) must be used when moving the source out of the device.

(((f))) (g) An exposure head or similar device designed to ((protect)) prevent the source assembly from passing out of the end of the guide tube must be attached to the outermost end of the guide tube during radiographic operations.

(h) The guide tube exposure head connection must be able to withstand the tensile test for control units specified in ANSI N432-1980.

(((g))) (i) Source changers must provide a system for ((assuring)) ensuring that the source will not be accidentally withdrawn from the changer when connecting or disconnecting the drive cable to or from a source assembly.

(((h) All newly manufactured radiographic exposure devices and associated equipment acquired by licenses after January 1, 1995, must comply with the requirements of this section.))

(((i))) (4) All radiographic exposure devices and associated equipment in use after January 1, 1998, must comply with the requirements of this section.

(((2) Limits on levels of radiation for radiographic exposure devices and storage containers:

(a) Radiographic exposure devices measuring less than four inches from the sealed source storage position to any exterior surface of the device shall have no radiation level in excess of fifty milliroentgens per hour (50mR/hr) at six inches from any exterior surface of the device.

(b) Radiographic exposure devices measuring a minimum of four inches from the sealed source storage position to any exterior surface of the device, and all storage containers for sealed sources or outer containers for radiographic exposure devices, shall have no radiation level in excess of two hundred milliroentgens per hour (200mR/hr) at any exterior surface, and ten milliroentgens per hour (10mR/hr) at one meter from any exterior surface.
