Oregon Revised Statutes Public Health and Safety § 453.665

(2)(a) Each application for a specific license shall be in writing and shall state such information as the authority by rule determines both to be necessary to decide the applicant's technical, insurance, financial or other qualifications and to be reasonable and necessary to protect occupational and public health and safety. At any time after the filing of the application for and before the expiration of a specific license the authority may require further written statements, and may cause inspections to be made as the authority considers necessary, to determine whether the license should be granted, denied, modified, amended, revised, suspended or revoked. An application for a specific license or any statement relating to that application or to any license must be signed by the applicant or licensee.

(b) Each license shall be in such form and contain terms and conditions the authority considers necessary to protect the occupational and public health and safety.

(c) A general or specific license or right to possess or use a radiation source under a general or specific license may not be assigned in any manner without the approval of the authority.

(d) The terms and conditions of any general or specific license may be modified, amended or revised by rule or order.

(e) Subject to any requirement for registration, the authority may by rule recognize a license from any other state or from the federal government as compliance with a license requirement of this section or of ORS 453.635.

(f) When the authority finds that a radiation source, a use of a radiation source, a user of a radiation source or a class of such sources, uses or users will not constitute a significant risk to the health and safety of the public, the authority may exempt the source, use, user or class, as the case may be, from any requirement for registration or a license.
