U.S. NRC Exempt Quantity Limits for Sources

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).
