The Nuclear Regulatory Commission has appointed Dr. Michael T. Ryan to its Advisory 

Committee on Reactor Safeguards (ACRS), an independent group of technical experts which 

advises the Commission on licensing and operation of nuclear power plants and related safety 

issues. Dr. Ryan previously chaired the Advisory Committee on Nuclear Waste & Materials, 

which was merged into the ACRS earlier this year. 

 Michael T. Ryan, Ph.D., C.H.P., is an independent consultant in radiological sciences and 

health physics. He has served on a number of national councils, including the Technical 

Advisory Control Council for the state of South Carolina for 19 years, and the National Council 

on Radiation Protection and Measurements since 1992. He is an adjunct faculty member at Texas 

A&M University and Vanderbilt University. Dr. Ryan has served as the editor-in-chief of the 

journal Health Physics since 2000. Prior to his career as a health physicist, he served as vice 

president and general manager for Chem-Nuclear Systems, Inc. 

Dr. Ryan received his doctorate in 1982 from the Georgia Institute of Technology, where 

he was later inducted into the Academy of Distinguished Alumni.
