subch. V of ch. DHS 157 Subchapter V — Radiation Safety Requirements for Well Logging

DHS 157.51 DHS 157.51 Prohibition.

DHS 157.51(1) (1) Well logging.

DHS 157.51(1)(a) (a) A licensee may not perform well logging with a sealed source unless, prior to commencement of the operation, the licensee has a written agreement with the well operator, well owner or land owner that includes all the following provisions:

DHS 157.51(1)(a)1. 1. In the event a sealed source is lost in the well, the licensee shall make a reasonable effort at recovery unless, in the licensee’s opinion, the recovery effort could result in rupture of the sealed source.

DHS 157.51(1)(a)2. 2. If a decision is made to abandon the sealed source in the well, the licensee shall meet the requirements of s. DHS 157.56 (3) and any requirements of the department of natural resources under chs. NR 141, 500 to 544, and 812.

DHS 157.51(1)(a)3. 3. If the environment, any equipment, or personnel are contaminated with licensed material, the equipment or personnel shall be decontaminated before release from the site or the site shall be decontaminated before release for unrestricted use.

DHS 157.51(1)(b) (b) The licensee shall retain a copy of the written agreement for three years after the completion of the well logging operation.

DHS 157.51(1)(c) (c) The licensee shall notify the department of natural resources prior to commencement of any operation involving well logging in a fresh water aquifer.

DHS 157.51(2) (2) Accelerators. A licensee or registrant may not permit above-ground testing of accelerators, designed for use in well logging, which results in the production of radiation, except in areas or facilities so controlled or shielded that the area or facility meets the requirements of s. DHS 157.21, as applicable.

DHS 157.51 History History: CR 01-108: cr. Register July 2002 No. 559, eff. 8-1-02; CR 06-021: renum. (1) to be (1) (a) and am. (1) (a) (intro.) to 2., cr.

DHS 157.52 DHS 157.52 Equipment control.

DHS 157.52(1) (1) Limits on levels of radiation. Sources of radiation shall be used, stored and transported in accordance with the transportation requirements of subch. XIII and the dose limitation requirements of subch. III.

DHS 157.52(2) (2) Storage precautions.

DHS 157.52(2)(a) (a) Each source of radiation, except accelerators, shall be provided with a storage or transport container. The container shall be equipped with a lock, or tamper seal for calibration sources, to prevent unauthorized removal of or exposure to the source of radiation.

DHS 157.52(2)(b) (b) A source of radiation shall be stored in a manner that minimizes danger from explosion or fire.

DHS 157.52(3) (3) Transport precautions. A transport container shall be physically secured to the transporting vehicle to prevent accidental loss, tampering or unauthorized removal.

DHS 157.52(4) (4) Radiation survey instruments.

DHS 157.52(4)(a) (a) A licensee or registrant shall maintain sufficient calibrated and operable radiation survey instruments at each field station and temporary job site to make physical radiation surveys as required by this subchapter and by s. DHS 157.25 (1). Instrumentation shall be capable of measuring one microsieverts (0.1 millirem) per hour through at least 0.5 millisieverts (50 millirem) per hour.

DHS 157.52(4)(b) (b) Each radiation survey instrument shall be calibrated according to all the following requirements:

DHS 157.52(4)(b)1. 1. At energies and geometry appropriate for use.
