How many questions are on the IRRSP exam?

The Industrial Radiography Radiation Safety Personnel (IRRSP) exam contains 100 multiple-choice questions. Candidates have three hours to complete the test, which is administered through approved certifying organizations such as the American Society for Nondestructive Testing (ASNT). All questions are scenario-based or knowledge-based on radiation safety principles.

What is the passing score for the IRRSP certification exam?

Candidates must achieve a minimum score of 70% to pass the IRRSP exam. This threshold is set by the Nuclear Regulatory Commission (NRC) under 10 CFR Part 34 and mirrored by Agreement States. Those who fail must wait a required period before retesting, typically 30 days.

What format does the IRRSP exam follow?

The IRRSP is a closed-book, computer-based or paper-based multiple-choice exam proctored at authorized testing centers. Candidates cannot bring reference materials, though a basic calculator is permitted for dose and shielding calculations. The exam tests both theoretical knowledge and practical application of radiation safety rules.

Who is eligible to take the IRRSP exam?

Eligibility requires candidates to be at least 18 years old and have documented on-the-job training under a certified radiographer. Most programs require a minimum of two months of practical field experience and completion of 40 hours of classroom instruction in radiation safety before sitting for the exam.

How do I register for the IRRSP exam?

Registration is handled through NRC-recognized certifying entities like ASNT or the International Municipal Signal Association. Applicants submit proof of training hours, employer verification, and the exam fee, which typically ranges from $150 to $300. Scheduling is done after application approval, usually within 30 days.

What topics are weighted most heavily on the IRRSP exam?

Radiation safety fundamentals, survey instrumentation, and regulatory requirements under 10 CFR Parts 20 and 34 make up the largest portions. Other key areas include radioactive source handling, emergency response, transportation regulations under 49 CFR, and ALARA principles. Shielding calculations and dose assessment are also tested.

How long is the IRRSP certification valid?

IRRSP certification is valid for five years from the date of issuance. Radiographers must recertify before expiration by either retaking the written exam or completing approved continuing education and demonstrating ongoing field experience. Lapsed certifications require full re-examination to restore active status.

What study resources work best for IRRSP exam preparation?

Effective preparation combines the NRC Regulatory Guide 8.7, ANSI N43.3 standards, and manufacturer manuals for survey meters and exposure devices. Candidates should review 10 CFR Parts 20, 34, and 71, practice dose rate calculations, and take timed practice tests covering source types like Iridium-192 and Cobalt-60.
