ACMUI Membership

The Advisory Committee on the Medical Uses of Isotopes (ACMUI) membership includes health care professionals from various disciplines. The ACMUI is composed of the following: a nuclear medicine physician; a nuclear cardiologist; a medical physicist in nuclear medicine unsealed byproduct material; a medical physicist in radiation therapy; a radiation safety officer; a nuclear pharmacist; two radiation oncologists; a patients' rights advocate; a Food and Drug Administration representative; an Agreement State representative; a health care administrator; and a diagnostic radiologist.

Membership on ACMUI is gained through a formal nomination and selection process. To fill vacancies on the ACMUI, NRC staff publishes a notice in the Federal Register requesting nominations from interested parties. After receipt of nominations, the NRC staff convenes a selection panel consisting of NRC employees and an individual who is a non-NRC Federal employee. This non-NRC Federal employee is always a professional who specializes in the vacancy to be filled. The selection panel evaluates each nominee and sends a recommendation for appointment by the Director, Office of Federal and State Materials and Environmental Management Programs. The Director reviews the recommendation, consults with the Commission, and appoints the ACMUI member.

ACMUI members are appointed to four-year terms and, with approval from NRC, may elect to serve up to two consecutive terms, for a maximum term of eight years.

For additional information on ACMUI membership see the list of ACMUI Specialties and Functions and NUREG/BR-0309, "Serving on the Advisory Committee on the Medical Uses of Isotopes (ACMUI): A Member's Guide."
