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.

Sample IRRSP - Industrial Radiography Radiation Safety Personnel Practice Questions
Try these questions from our free IRRSP - Industrial Radiography Radiation Safety Personnel practice tests. The correct answer and an explanation follow each question.
According to 10 CFR Part 34, which of the following is a required daily operability check that must be performed on a radiographic exposure device before its first use of the day?
- A. A leak test of the sealed source.
- B. Verification of the source's activity using a calibration certificate.
- C. A visual check of the drive cable for kinks and fraying.
- D. Disassembly and lubrication of the crank mechanism.
Answer: C. A visual check of the drive cable for kinks and fraying.
10 CFR 34.31 requires licensees to perform visual and operability checks on radiographic exposure devices and associated equipment before use each day. This includes inspecting the crank, drive cable, and guide tube connections for any damage or defects that could compromise safety.
Under which of the following conditions is a vehicle required to be placarded with 'RADIOACTIVE' signs on all four sides?
- A. Anytime a Type A package is transported.
- B. When the vehicle is carrying a package with a RADIOACTIVE WHITE-I label.
- C. When the vehicle is carrying a package with a RADIOACTIVE YELLOW-III label.
- D. If the total activity in the vehicle exceeds 10 Curies.
Answer: C. When the vehicle is carrying a package with a RADIOACTIVE YELLOW-III label.
According to 49 CFR 172.504, placarding of the transport vehicle is required for any shipment that includes a package bearing a RADIOACTIVE YELLOW-III label. Placarding is not required for packages with only WHITE-I or YELLOW-II labels.
Which device is commonly used to monitor individual radiation exposure in industrial radiography?
- A. Thermometer
- B. Voltmeter
- C. Pressure gauge
- D. Personal dosimeter
Answer: D. Personal dosimeter
A personal dosimeter is the specific device designed to monitor individual radiation exposure. These small, wearable devices measure the cumulative radiation dose received by the wearer over a period. They are crucial for tracking occupational exposure and ensuring compliance with radiation safety limits.
A radiographer's transport vehicle is involved in a traffic accident. After confirming no medical emergencies exist, what is the radiographer's first and most critical radiological safety action?
- A. Immediately notify the company's Radiation Safety Officer (RSO).
- B. Exchange insurance information with the other driver and then survey the equipment.
- C. Perform a thorough radiation survey of the exposure device and the immediate area to verify shielding integrity.
- D. Remove the exposure device from the vehicle and place it at least 50 feet away from the accident scene.
Answer: C. Perform a thorough radiation survey of the exposure device and the immediate area to verify shielding integrity.
The immediate priority in any incident involving a radiographic device is to assess the radiological conditions. A survey must be performed to confirm that the source is still properly shielded and that there is no radiation hazard to the public, emergency responders, or the radiographer before any other non-life-saving actions are taken.
