Michael E. Ketterer
Michael E. Ketterer, PhD, is an analytical chemist and Professor Emeritus of Chemistry and Biochemistry at Northern Arizona University (NAU).
He specializes in understanding the sources, transport, and environmental fates of long-lived radioactive contaminants (such as uranium and plutonium) near former and active nuclear sites.
He has performed mass spectrometric studies of uranium isotopes in off-site samples near the Portsmouth Nuclear Site (PORTS) which show conclusively that the contamination originated from PORTS.
Dr. Ketterer provides expert technical assistance to affected communities.
