ABHP Health Physics Part I Examination Practice Test
The ABHP Health Physics Part I Examination is the foundational certification for professionals seeking recognition as a Qualified Health Physicist (QHP) in the United States. Administered by the American Board of Health Physics (ABHP), this rigorous exam validates a candidate's comprehensive understanding of core health physics principles, radiation protection standards, and their practical application. Achieving Part I certification is a critical milestone, demonstrating a professional's mastery of the scientific and technical fundamentals required to ensure the safe use of ionizing radiation in diverse settings, including nuclear power, medicine, research, and national security. This credential is not merely an academic exercise; it is a recognized industry standard that signifies technical competence, a commitment to public and occupational safety, and adherence to the highest professional ethics. It serves as a prerequisite for the ABHP Part II (Oral) Examination and is often a mandatory or highly preferred qualification for senior health physics roles, establishing the certified individual as a trusted authority in the field.

25 of 72 answers carry a checkable reference.
An injured worker arrives from a radiochemistry hot cell with a bleeding laceration and suspected removable contamination on clothing. Security wants the worker held outside until the survey team arrives. What procedure is best?
A respirator is proposed for cleanup at a linac target vault because airborne beta contamination may exceed an action level for 30 minutes. The worker has no fit test this year and the nuclide mix is uncertain. What programmatic answer is best?
A job-task analysis at a radiochemistry hot cell shows new technicians calculate DAC-hours, respond to CAM alarms, package excepted quantities, and brief nontechnical lab users. Which training approach is best?
A respirator is proposed for cleanup at a waste assay area because airborne beta contamination may exceed an action level for 30 minutes. The worker has no fit test this year and the nuclide mix is uncertain. What programmatic answer is best?
A maintenance crew at a research reactor support building must open a pump that may contain fixed beta contamination and small amounts of removable Cs-137. The craft procedure lists torque steps but no radiological hold points. What RWP control is most important to add?
