(a) Documented and maintained for inspection for a minimum of three years. This record shall contain such information as date the alteration was made, type of alteration, length of time alteration remained in place, and signature of the individual who made the alteration and the individual who restored the safety device to the original condition; and
(b) Approved, and signed in advance for a specified period of time by the individual responsible for radiation protection, and posted near the radiation-generating source housing with the signatures of approval.
(3) Except as specified in paragraph (B)(2) of this rule, no operation involving removal of covers, shielding materials or radiation source housings or modifications to shutters, collimators, or beam stops shall be performed without ascertaining that the radiation source is off and will remain off until safe conditions have been restored. The radiation source power switch, in conjunction with appropriate interlocks, shall be used for routine shutdown in preparation for repairs.
(4) Industrial analytical radiation-generating equipment shall not be used to intentionally irradiate human beings.
(C) In addition to the requirements in rule 3701:1-68-02 of the Administrative Code, handlers of industrial analytical radiation-generating equipment shall comply with the following quality assurance requirements:
(1) The local components of an industrial analytical radiation-generating system shall be located, arranged, and include sufficient shielding or access control such that no radiation levels exist in any area surrounding the local component group which could result in a dose to an individual present therein in excess of the dose limits given in Chapter 3701:1-38 of the Administrative Code. These levels shall be met at any specified radiation source rating.
(2) Radiation surveys of all industrial analytical radiation-generating systems shall be performed in compliance with the rules of Chapter 3701:1-38 of the Administrative Code:
(a) Upon installation of the radiation-generating equipment;
(b) Following any change in the initial arrangement, number, or type of local components in the system;
(c) Following any maintenance requiring the disassembly or removal of a local component in the system;
(d) During the performance of maintenance and alignment procedures if the procedures require the presence of a primary x-ray beam when any local component in the system is disassembled or removed;
(e) Any time a visual inspection of the local components in the system reveals an abnormal condition; and
(f) Whenever personnel monitoring reports show an unexplained increase over the previous monitoring period or the readings are approaching the limits specified in rules adopted pursuant to Chapter 3701:1-38 of the Administrative Code.
(3) Proper operation of all radiation safety devises, such as interlocks, lights and labels, shall be checked at least every six months by individuals qualified according to paragraph (C)(4) of this rule. Documentation shall be maintained and available for inspection for a minimum of three years and shall include any corrective actions taken.
(4) No individual shall be permitted to operate or maintain industrial analytical radiation-generating equipment unless that individual has received training and demonstrated competence regarding the following:
(a) Identification of radiation hazards associated with the use of the equipment;
(b) Significance of the various radiation warning, safety devices, and interlocks incorporated into the equipment, or the reasons they have not been installed on certain pieces of equipment and the extra precautions required in such cases;
(c) Standard operating procedures for the equipment;
(d) Recognition of symptoms of an acute localized exposure;
(e) Proper procedures for reporting an actual or suspected exposure in accordance with in rule 3701:1-38-21 of the Administrative Code.
