DC 20590 Pipeline and Hazardous Materials Safety Administration NOV 8 2011 Mr. James E. Lynch Mirion Technologies 315 Daniel Zenker Dr. Building 300 iST Center Horseheads, NY 14845 Ref. No. 11-0216 Dear Mr. Lynch: This responds to your September 6, 2011 request for clarification ofthe Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to radiation detectors. In your letter, you describe your company's radiation detector as a non-refillable and hermetically sealed welded metallic cylinder with up to three brazed ceramic-to-metal seals (small electrical penetrations) that contains a Division 2.2 (Non-flammable compressed gas) material. Your questions are summarized and answered as follows: Q1) Section § 173.310 contains regulations applicable to radiation detectors. Does the radiation detector described in your letter meet the definition of"single-trip" and "welded metal inside container" as required by § 173.31O(a). AI) Yes. Section 173.310(a) requires a radiation detector to be single-trip, hermetically sealed, welded metal inside container that will not fragment upon impact. The radiation detector described in your letter is a "welded metal inside container." The term "single-trip" means that the inner packaging is not intended to be refilled and reshipped after having been previously emptied. Q2) You plan to include a vendor certification letter that the product and its packaging conforms to § 173.310. Will customers be able to use the letter/certification to return the product to your company ifthe customers use your packaging materials and procedure? A2) Yes. However, in accordance with § 173.22 it is the shipper's responsibility to comply with aspects of the HMR applicable to offering a hazaIdous material for transportation. The <<>> letter/certification that you plan to provide your customers will provide valuable information to assist them in satisfying the compliance responsibilities specified in§ 173.22. I hope this answers your inquiry. If you need additional assistance, please contact this office at (202) 366-8553.

I believe that we meet the intent of 49 C.F.R. 173.310 however would appreciate an interpretation on its wording. SUBJECT: Mirion (1ST) Special Permit DOT-SP 7946 renewal application denial letter dated August 19,2011 and use of 49 C.F.R. § 173.310. We received the subject renewal application denial letter and understand the intent is to use §173.310. In reviewing §173.31O, as it pertains to shipping our product/ we seek clarification. In particular, §173.310 (a) states "Radiation detectors must be single-trip, hermetically sealed, welded metal inside containers that will not fragment upon impact." As described in our expired Special Permit, our radiation detectors are "non-refillable" and hermetically sealed, however, their construction is a welded metallic cylinder with up to three brazed ceramic-to-metal seals (small electrical penetrations). We believe that our radiation detectors meet the requirements of §173.310, however, are unsure of the meaning of "single-trip" and the exactness of "welded metal inside containers", We would appreciate your review of our described product and concurrence it conforms to §173.310 (a). If there are any questions please contact me. I look forward to your response. Secondly, I have embedded our revised packaging specification in hopes you will review it for correctness. We plan to include a vendor certification letter that the product and its packaging conforms to 173.310. Our hope is that our 1 <<>> customers could use this letter / certification in returning the product to us as long as they use our packaging materials and procedure.
