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.

This research investigates the effect of heterogeneity in slabs of aluminum, stainless steel, and polyethylene on photon and neutron transmission. This work considers whether novel, heterogeneous combinations of these materials provides improved photon shielding (for metal-infiltrated polyethylene) or neutron shielding (for polyethylene-infiltrated metal). Often, layers of a hydrogenous material such as polyethylene must be combined with layers of a higher-atomic-number material to provide shielding for both photons and neutrons. Several heterogeneous shield configurations are studied in which slabs of a base material are implanted with metal stud arrays ranging from 5 × 5 × 5 to 11 × 11 × 11 arrays. For metal slabs infiltrated with polyethylene studs, it is found that the performance of the heterogeneous slabs as neutron shields relative to the homogeneous material is source-energy dependent. This is a larger concern for polyethylene-infiltrated aluminum (PA) than it is for polyethylene-infiltrated stainless steel (PS) as introduction of these studs impairs PA’s performance as a photon shield (relative to solid aluminum) more than it does for PS relative to solid stainless steel. For polyethylene slabs infiltrated with aluminum or stainless steel studs, it is found that introduction of a sufficiently spaced array of metal studs with a moderate-to-high photon absorption cross section will improve the photon-shielding properties of the shield without impairing the neutron-shielding properties. Use of an insufficiently opaque material or insufficiently wide spacing of the studs will impair the photon-shielding properties, thus making it a less effective shield than homogeneous polyethylene alone. This is a larger concern for PA than it is for PS. This research demonstrates that heterogeneity is more beneficial for stainless steel shields than it is for heterogeneous aluminum shields relative to homogeneous slabs of those materials.
