Ariz. Admin. Code § R9-7-1718 - Design and Performance Criteria for Sealed Sources

A. A licensee shall use a sealed source for well logging applications if the sealed source:

1. Is doubly encapsulated;

2. Contains licensed material in a chemical and physical form that is insoluble and nondispersible; and

3. Meets the requirements of subsection (B), (C), or (D).

B. For a sealed source manufactured on or before July 14, 1989, a licensee may use a sealed source in well logging applications that meets the requirements of USASI N5.4-1968, Classification of Sealed Radioactive Sources, available from the American National Standards Institute at 25 West 43rd Street, 4th floor, New York, NY 10036, which is incorporated by reference and on file with the Department, or the requirements in subsection (C) or (D). This incorporation by reference contains no future editions or amendments.

C. For a sealed source manufactured after July 14, 1989, a licensee may use a sealed source in well logging applications that meets the oil-well logging requirements of ANSI/HPS N43.6-1997, Sealed Radioactive Sources--Classification, available from the American National Standards Institute at 25 West 43rd Street, 4th floor, New York, NY 10036, which is incorporated by reference and on file with the Department. This incorporation by reference contains no future editions or amendments.

D. For a sealed source manufactured after July 14, 1989, a licensee may use a sealed source in well logging applications if the sealed source's prototype has been tested and found to maintain its integrity after each of the following required tests:

1. Temperature. The test source is held at -40° C for 20 minutes and 600° C for one hour, and then subjected to a thermal shock with a temperature drop from 600° C to 20° C within 15 seconds.

2. Impact. A 5 kg steel hammer, 2.5 cm in diameter, is dropped from a height of 1 m onto the test source.

3. Vibration. The test source is subjected to vibration in the 25 Hz to 500 Hz range at 5 g amplitude for 30 minutes.

4. Puncture. A 1 gram hammer with a pin, 0.3 cm in diameter, is dropped from a height of 1 m onto the test source.

5. Pressure. The test source is subjected to an external pressure of 1.695 x 107 pascals (24,600 pounds per square inch absolute).

E. The requirements in subsections (A), (B), (C), and (D) do not apply to a sealed source that contains licensed material in gaseous form.

F. The requirements in subsections (A), (B), (C), and (D) do not apply to an energy compensation source (ECS).
