The Joyce P. Davis Memorial Award honors individuals who embody the values Joyce P. Davis championed — excellence in health physics, humanitarian service, and unwavering ethical leadership. This year’s recipient, Jeffrey Chapman, CHP, reflects those qualities in every aspect of his career.

For more than four decades, Jeff has advanced health physics through public service, national security work, emergency response, and technical innovation. His contributions span Oak Ridge National Laboratory, Canberra Industries, ORAU, and the NNSA’s Nuclear Emergency Support Team. He has shaped national and international standards, supported critical safeguards missions, and even co invented patented radiation measurement technology.

Jeff’s professional stature is exceptional: he is a Fellow of the Health Physics Society, a Registered Professional Engineer in Nuclear Engineering, and currently serves as Chair of the American Board of Health Physics, following years of dedicated service on its Part II Panel and NCRP scientific committees.

The ABHP Bill Fitzgerald Service award honors those Certified Health Physicists who have provided exceptional service to the ABHP. These are the individuals who volunteer for any and all tasks, no matter how hard they may be or how long they may take. More so, they complete these tasks promptly, in an outstanding manner, and do so selflessly because they know that it’s the right thing to do.

As the immediate past president of the ABHP, it is my honor, my pleasure, and my privilege to present this year’s ABHP Bill Fitzgerald Service Award to Professor Wei-Hsung Wang.

Dr. Wang’s commitment to the missions and objectives of the ABHP cannot be overstated. He served as a member of the Part II Panel of Examiners from 2008 to 2018, where he was the Part II Panel Vice Chair in 2015 and Panel Chair in 2016. Immediately after rolling off the Part II Panel, Professor Wang then became an ABHP Board member, serving from 2018 to 2023. He became the ABHP Board Vice Chair in 2020 and Board Chair in 2021. As a Board Member and Board Chair, Professor Wang developed numerous initiatives to modernize the ABHP exam and make it more readily available and equitable. Now one would think that after fifteen years of continual service, Dr. Wang would take a break from the ABHP. from the ABHP. Yet it isn’t in his character to do so… From the ABHP Board, Professor Wang went right back to the Part II Panel where he presently is serving another five year term. He is truly one of a kind and I count myself very lucky to be colleagues with this man.
