DHS 157.52(9)(d)(d) In the case of tracer materials and radioactive markers, the utilization record shall indicate the radionuclide and activity used in a particular well and the disposition of any unused tracer material.

DHS 157.52(10)(a)(a) Each sealed source, except those containing radioactive material in gaseous form or in energy compensation sources (ECS), used in well logging applications, shall meet all the following criteria:

DHS 157.52(10)(a)2.2. Contain licensed material whose chemical and physical forms are as insoluble and non-dispersable as practical.

DHS 157.52(10)(b)(b) Each sealed source, except those used in energy compensation sources (ECS), shall meet one of the following requirements:

DHS 157.52(10)(b)1.1. For a sealed source manufactured on or before July 14, 1989, the requirements from the United States of America Standards Institute N5.10-1968, “Classification of Sealed Radioactive Sources.”

DHS 157.52(10)(b)2.2. For a sealed source manufactured after July 14, 1989, the oil-well logging requirements from the American National Standard Institute/Health Physics Society N43.6-1997, “Sealed Radioactive Sources-Classification.”

DHS 157.52(10)(b)3.3. For a sealed source manufactured after July 14, 1989, the sealed source’s prototype has been tested and found to maintain its integrity after each of the following tests:

DHS 157.52(10)(b)3.a.a. Temperature. The test source shall be held at -40 degrees Celsius for 20 minutes, 600 degrees Celsius for one hour, and then be subjected to a thermal shock test with a temperature drop from 600 degrees Celsius to 20 degrees Celsius within 15 seconds.

DHS 157.52(10)(b)3.b.b. Impact. A 5 kilogram (kg) steel hammer, 2.5 centimeters in diameter, shall be dropped from a height of 1 meter (m) onto the test source.

DHS 157.52(10)(b)3.c.c. Vibration. The test source shall be subjected to a vibration from 25 Hertz (Hz) to 500 Hz with a peak amplitude of five times the acceleration of gravity for 30 minutes.

DHS 157.52(10)(b)3.d.d. Puncture. A 1 gram (gm) hammer and pin, 0.3 centimeter (cm) pin diameter, shall be dropped from a height of 1 meter (m) onto the test source.

DHS 157.52(10)(b)3.e.e. Pressure. The test source shall be subjected to an external pressure of 24,600 pounds per square inch absolute (1.695 X 107 pascals) without leakage.

DHS 157.52(10)(c)(c) Licensee use of an energy compensation source, which may contain quantities no greater than 3.7 MBq (100 microcuries), is exempt from the requirements of this subchapter, except for all the following:

DHS 157.52(10)(c)1.1. A licensee using an ECS in a well with a surface casing for protecting fresh water aquifers shall meet the requirements of subs. (5) to (9).

DHS 157.52(10)(c)2.2. A licensee using an ECS in a well without a surface casing for protecting fresh water aquifers shall meet the requirements of subs. (5) to (9), and ss. DHS 157.51 (1) (a), 157.53 (2) and 157.56.

DHS 157.52(10)(d)(d) Licensee use of a tritium neutron generator target source is exempt from the following requirements of this subchapter:

DHS 157.52(10)(d)1.1. A licensee using a tritium neutron generator target source, containing quantities no greater than 1,110 GBq (30 curies), in a well with a surface casing to protect fresh water aquifers is exempt from the requirements of s. DHS 157.56 and this subsection except for pars. (a) and (b) for tritium neutron generator target source use only.

DHS 157.52(10)(d)2.2. A licensee using a tritium neutron generator target source, containing quantities exceeding 1,110 GBq (30 curies), or in a well without a surface casing to protect fresh water aquifers is exempt from the requirements of this subsection except for pars. (a) and (b) for tritium neutron generator target source use only.

DHS 157.52(11)(a)(a) Each source, source holder or well logging tool containing radioactive material shall bear a durable, legible and clearly visible marking or label which has, as a minimum, the standard radiation caution symbol, without the conventional color requirement, and the following wording:
