On January 31, 2019, the NRC issued an SL III NOV to Howard University. The violation involved the university’s possession of byproduct material that was not authorized under its license. Specifically, while cleaning out a laboratory, Howard University staff located a container of powdered actinium-227, which the facility had apparently received in 1942. The actinium-227 was not exempt from licensing requirements and was not authorized by the university’s NRC license.
