ABHP Panels

The ABHP Panels of Examiners prepare and evaluate the two certification examinations given by the ABHP each year. The Part I exam covers fundamentals of health physics and is in multiple-choice format. The Part II exam has longer format answers and also covers applications of health physics. Click on either of the following two links to find out more about each Panel

Members of each panel are selected by the ABHP. Panel members serve for a four-year term, unless the member is chosen as the Panel Chair, who serves an extra year. Each panel meets once each year to prepare the next examination.

The first panel was created in 1960. The multiple-choice format Part I examination was split off as a separate part of the certification process in 1968. The single Panel of Examiners was responsible for both the Part I and Part II exams until the formation of a separate Part I Panel of Examiners in 1988. The Part II Panel was further split from 1979-1993 when a Specialty Certification was offered in Power Reactor Health Physics.
