IRRSP Practice Test PDF – Industrial Radiography Radiation Safety Personnel
The IRRSP certification is issued by the NRC and Agreement State agencies to individuals who supervise or perform industrial radiography operations. This free printable practice test PDF covers all major domains of the IRRSP examination so you can prepare thoroughly and study offline at your convenience.
Topics include radiation physics, industrial radiography equipment, NRC regulations, personnel monitoring, emergency response procedures, and controlled area requirements. Download and print this PDF to reinforce your knowledge before your certification exam date.
How to Use This IRRSP Practice Test PDF
Work through each question in the PDF without referencing your notes first, then check your answers against the explanations provided. This approach simulates the closed-book format of the IRRSP exam and helps you identify which domains require additional study. Pay close attention to the NRC regulatory questions, as knowledge of 10 CFR Part 34 requirements is essential for passing.
After completing the full practice test, focus your remaining study time on any topic where you answered fewer than 80% of questions correctly. Radiation physics and emergency procedures are two areas where candidates commonly lose points, so give those sections extra attention before your exam.
Identify the four main types of ionizing radiation and their penetrating properties Apply the inverse square law to calculate dose rate at various distances from a source Understand shielding materials and their effectiveness for gamma versus X-ray sources Know the components of a gamma projector and the function of each part Differentiate between Ir-192 and Se-75 in terms of energy, half-life, and application Memorize the key provisions of 10 CFR Part 34 including licensing and recordkeeping Understand Agreement State authority and how it compares to direct NRC jurisdiction Review dosimeter types, their dose limits, and proper wearing and exchange procedures Practice the step-by-step source-stuck emergency response protocol in correct order Know the posting and barrier requirements for establishing a controlled radiography area About the IRRSP Certification Exam
The IRRSP examination tests candidates on their ability to safely plan, supervise, and perform industrial radiography operations in compliance with NRC and Agreement State regulations. The exam is typically administered by a state radiation control program or approved testing provider and covers both theoretical knowledge and practical regulatory requirements.
Candidates must demonstrate competency across all tested domains before they are authorized to act as a Radiation Safety Personnel supervisor on industrial radiography projects. This practice test PDF is designed to help you meet that standard by exposing you to the full range of question types and regulatory topics you will encounter on the real exam.
IRRSP Study Tips
💡 What's the best study strategy for IRRSP?
Focus on weak areas first. Use practice tests to identify gaps, then study those topics intensively.
📅 How far in advance should I start studying?
Most successful candidates begin 4-8 weeks before the exam. Create a structured study schedule.
🔄 Should I retake practice tests?
Yes! Take each practice test 2-3 times. Focus on understanding why answers are correct, not memorizing.
✅ What should I do on exam day?
Arrive 30 min early, bring required ID, read questions carefully, flag difficult ones, and review before submitting.

What regulations must I know for the IRRSP exam?
The IRRSP exam places heavy emphasis on NRC 10 CFR Part 34, which governs licenses for industrial radiography. If you are in an Agreement State, you must also know your state-specific equivalent rules, which generally mirror Part 34 but may include additional requirements unique to your jurisdiction.
What radioactive sources are commonly tested on the IRRSP exam?
Iridium-192 (Ir-192) and Selenium-75 (Se-75) are the two gamma sources most commonly covered. You should know their typical energies, half-lives, and the types of industrial applications each source is suited for, as these details appear frequently in both regulatory and equipment questions.
How hard is the IRRSP certification exam?
The IRRSP exam is considered moderately challenging. The regulatory portions covering 10 CFR Part 34 and emergency procedures tend to be the most demanding for new candidates. Consistent study using this practice PDF — combined with hands-on field experience — gives you the best chance of passing on your first attempt.
Can I download and print this IRRSP practice test PDF for free?
Yes. The PDF is completely free to download and print. There are no sign-ups or fees required. You can print multiple copies to share with study partners or complete the test more than once to track your progress over time.
