Ohio Administrative Code
Title 3701:1 - Radiation Control
Chapter 3701:1-66 - Radiation Generating Equipment
Section 3701:1-66-02 - General administration requirements for medical radiation-generating equipment
Current through all regulations passed and filed through March 18, 2024
As used in this rule, "radiation-generating equipment" means radiation-generating equipment used for dental, veterinary, or medical purpose but does not include therapeutic radiation-generating equipment.
(A) The director may, upon application thereof or upon his or her own initiative, grant a variance to the requirements of rules in this chapter as he or she determines is authorized by law, provided that the registrant shows to the satisfaction of the director that there is good cause for the variance, and that the variance will not result in any undue hazard or effect on the public health and safety or environment. The terms, conditions, and expiration of the variance shall be set forth in writing by the director. Failure to comply with the terms of the variance may result in immediate revocation of the variance.
(B) Except as specified in rule 3701:1-66-17 of the Administrative Code, no individual shall be exposed to the useful beam except a patient for dental or medical radiologic procedures and unless such exposure has been authorized by a licensed practitioner within his or her scope of practice. This provision specifically prohibits deliberate exposure for the following purposes:
(C) The handler shall assure:
(D) Any radiation-generating equipment that does not meet the provisions set forth in this rule or any other applicable equipment requirements of Chapter 3701:1-66 of the Administrative Code shall not be used to irradiate patients unless the director or a radiation expert determines that the non-compliance will not pose a radiation risk and arrangements have been made to promptly correct the non-compliance.
(E) Radiation-generating equipment shall bear a warning label on the control panel, by the exposure switch or by the main power switch which cautions individuals that radiation is produced when it is energized.
(F) Unless otherwise specified in this paragraph, radiation-generating equipment shall meet the following standards:
