U.S. NRC Exempt Quantity Limits for Sources
Small amounts of some byproduct material may be purchased without a specific license per the U.S. NRC § 30.18 Exempt quantities or the equivalent Agreement State regulations.
“(a) Except as provided in paragraphs (c) through (e) of this section, any person is exempt from the requirements for a license set forth in section 81 of the Act and from the regulations in parts 30 through 34, 36, and 39 of this chapter to the extent that such person receives, possesses, uses, transfers, owns, or acquires byproduct material in individual quantities, each of which does not exceed the applicable quantity set forth in § 30.71, Schedule B.”
How to Dispose of Exempt Quantity Sources in the U.S.
Spectrum Techniques’ solid, sealed sources may be disposed of in the regular waste without regard to their radioactive content providing the customer is not a specific licensee and all radiation symbols have been removed or defaced. It is recommended that liquid sources be disposed of by release into the sanitary sewer system (making sure to dilute the material with large volumes of water).
If the customer is a specific licensee, then the customer is subject to the requirements of 10 CFR Part 20 in the areas where 10 CFR 30.18 is silent (e.g., waste disposal).
