SECTION 252:410-17-8. Industrial electron beam systems

(a)   Defined. An industrial electron beam system means a radiation machine which is a type of particle accelerator used in manufacturing processes including curing, polymer linking, thickness measurements or coating weight, and quality control on continuously moving webs.

(b)   System requirements. Prior to using an industrial electron beam system, a permittee must ensure each system meets the following requirements:

(1)   The system must use only electrons that are accelerated by voltages of less than 500 kV;

(2)   The high radiation area created when the system is energized must not be large enough for a person to enter;

(3)   Ionizing radiation produced by such a system must be contained within an interlocked, shielded cabinet designed to maintain surface doses below 0.2 mR/hr;

(4)   Each system must have a sign, located near any control that energizes the system, bearing the radiation symbol and the following words, "CAUTION RADIATION - THIS EQUIPMENT PRODUCES RADIATION WHEN ENERGIZED" or words having similar intent;

(5)   Each area or room containing a system shall be posted with a sign or signs bearing the radiation symbol and the words: "CAUTION - RADIATION PRODUCING EQUIPMENT" or words having similar intent; and

(6)   The system must be maintained to the manufacturer's specifications and operated in compliance with the manufacturer's operating procedures.

(c)   Surveys. In addition to the requirements of this Subchapter, persons using such systems must comply with the survey requirements of 252:410-13-3(b).

(d)   Exemptions. Systems meeting the requirements of subsections (a) and (b) of this section are exempt from:

(1)   the scram button requirements of 252:410-17-3(c);

(2)   the audible warning and posting requirements of 252:410-17-4(b) and (c); and

(3)   the monitoring requirements of 252:410-17-6(c)-(f).
