HPS's Eric Goldin: On health physics
Eric Goldin, president of the Health Physics Society, is a radiation safety specialist with 40 years of experience in power reactor health physics, supporting worker and public radiation safety programs. A certified health physicist since 1984, he has served on the American Board of Health Physics, and since 2004, he has been a member of the National Council on Radiation Protection and Measurements’ Program Area Committee 2, which provides guidance for radiation safety in occupational settings for a variety of industries and activities. He was awarded HPS Fellow status in 2012 and was elected to the NCRP in 2014.
Goldin’s radiological engineering experience includes ALARA programs, instrumentation, radioactive waste management, emergency planning, dosimetry, decommissioning, licensing, effluents, and environmental monitoring.
The HPS, headquartered in Herndon, Va., is the largest radiation safety society in the world. Its membership includes scientists, safety professionals, physicists, engineers, attorneys, and other professionals from academia, industry, medical institutions, state and federal government, the national laboratories, the military, and other organizations.
The HPS’s activities include encouraging research in radiation science, developing standards, and disseminating radiation safety information. Its members are involved in understanding, evaluating, and controlling the potential risks from radiation relative to the benefits.
Goldin talked about the HPS and health physics activities with Rick Michal, editor-in-chief of Nuclear News.

Monoenergetic neutron production by nuclear reactions among light elements and the production of white neutrons by such reactions are of particular interest for fusion applications. Data reduction of continuous neutron spectra is generally hampered by a lack of adequate background spectra. To find the best background spectrum for the measurement of 3H(t,n) double-differential cross sections, much effort was applied to determining a reliable background spectrum stemming from a tritium gas cell. Since the measurement of the 2H(t,n)4He reaction that was used for the efficiency determination used the same gas cell, the same background spectra could be used, and continuous neutron spectra stemming from the three-body (n+X+Y) reactions of 2H(t,n)X+Y could be extracted reliably. Thus, double-differential three-body neutron production cross sections were determined at 5.97, 7.47, 10.45, and 16.41 MeV, at angles between 0 and 90 deg with a scale uncertainty of <4%. Corresponding data with projectile and target particles exchanged are available in the same center-of-mass energy range with uncertainties of ~25%.
