Sec. 1. (a) This rule establishes the requirement for the issuance of a license authorizing radioactive materials in irradiators used to irradiate objects or material using gamma radiation. This rule also establishes radiation safety requirements for operating irradiators.

(b) This rule applies to panoramic irradiators that have either dry or wet storage of the radioactive sealed sources, and to underwater irradiators in which both the source and product being irradiated are under water. Irradiators whose dose rate exceeds five (5) grays (500 rads) per hour at one (1) meter from the radioactive sealed sources in air or water, as applicable for the irradiator type, are covered by this rule.

(c) The requirements set out in this rule do not apply to self-contained dry source storage irradiators in which both the source and area subject to irradiation are contained within a device and are not accessible by personnel, medical radiology or teletherapy, radiography (the irradiation of materials for nondestructive testing purposes), gauging, or open-field (agricultural) irradiations.

(d) The requirements of this rule are in addition to, and not in substitution for, other requirements of this article. The provisions of 290 IAC 3-2 through 290 IAC 3-9 and 290 IAC 3-11 through 290 IAC 3-18 also apply.

(e) Nothing in this rule relieves the licensee from complying with other applicable federal, state, and local regulations governing the siting, zoning, land use, and building code requirements for industrial facilities.
