Try a sample questionExam overview and details
Health physics board certification for radiation protection professionals covering radiation physics, instrumentation, dosimetry, regulatory compliance, and shielding design. Administered by American Board of Health Physics. Key domains include Measurements and Instrumentation, Hazards Analysis and Controls, Operations and Procedures and Standards and Requirements.
Sample Questions
Choose an answer and explore the explanation to see how practice works.
A check source reading on a survey meter is 18 percent below the established control-chart mean but still inside the manufacturer's broad tolerance. The meter will be used for release surveys. What is the best action?
A radiological environmental monitoring program samples only the site boundary downwind of the prevailing annual wind direction. A new stack release point operates mainly during winter inversions. What should be revised?
A spent-source storage room has low routine dose rates, but a fire analysis shows potential airborne release if sealed sources fail in a severe fire. Which control is most directly responsive to that accident scenario?
An ion chamber is selected to measure a pulsed high dose-rate X-ray field from an interventional unit. A GM meter in the same field repeatedly saturates and then recovers. Why is the ion chamber preferred for this measurement?
A maintenance department wants one generic radiation work permit for all valve work in a reactor auxiliary building. Dose rates range from background to 80 mrem/h, and some valves have contamination histories. What procedure feature is most important?
Exam insights and study advice
In the real world, the decisions of a Health Physicist have direct consequences for worker and public safety, environmental stewardship, and regulatory compliance. A CHP is often the responsible authority for ensuring the safe use of radiation in medicine (like cancer therapy and diagnostics), nuclear power generation, national laboratories, industrial applications, and academic research. The credential matters because it provides an objective, peer-reviewed standard of excellence. It assures that complex safety analyses, dose assessments, and protection programs are managed by individuals with proven, comprehensive expertise, thereby preventing overexposures, ensuring legal operation, and maintaining public trust in vital technologies.
What this exam covers
Use the published domain weights to plan your study. Practice results do not predict your certification exam score.
01Measurements and Instrumentation
This domain covers measurements and instrumentation, focusing on the selection and use of measuring instruments, data quality objectives, quality control, calibration, maintenance, and performance testing of instrumentation used in radiation protection settings.
02Hazards Analysis and Controls
This domain covers hazards analysis and controls, focusing on hazard identification, engineered controls, potential failures of protective control systems, and evaluating potential radiological consequences to ensure safety in diverse work environments.
03Operations and Procedures
This domain covers operations and procedures, incorporating radiation protection considerations into an operating program, standard operating practices, and effective emergency response measures to maintain safety during all routine and non-routine facility activities.
04Standards and Requirements
This domain covers standards and requirements, addressing guidelines from established groups like ICRP, NCRP, ANSI, and ASTM, alongside the specific requirements of regulatory agencies such as NRC, DOE, EPA, DOT, OSHA, and FEMA.
05Fundamentals and Education
This domain covers fundamentals and education, including the content of training the health physicist receives and the educational programs prepared, reviewed, and presented to staff members within the radiation protection department.
