ExploreAbout this exam
The GER Category 2 credential is a radiation-protection certification for people who work with, supervise, or regulate radioactive sources and radiation-generating equipment in industrial settings. Candidates typically come from industrial radiography, source management, transport logistics, regulatory inspection, and radiation safety officer roles. The exam tests whether you can apply the regulatory framework and safety principles in practice, not just recall definitions. Coverage spans the regulatory and legislative basis for licensed activities, radiation protection and dose limitation, source and equipment characteristics, radiographic operational practice, emergency preparedness and response, transport and storage requirements, and quality management with record keeping. Expect scenario-based items: a source fails to retract, a package is mislabelled, a dosimetry result is anomalous, or a record is missing. Preparation usually combines the national regulatory instruments and guidance with a radiation physics and protection text, then moves to operational procedures and emergency drills. Work through past operational incidents and ask what the correct action, notification, and documentation would be at each step. Because exam logistics change, confirm the current question count, duration, fee, passing score, and retake rules directly with the official certifying body rather than relying on second-hand summaries.
What you'll study
About GER Category 2 preparation
Who should sit the GER Category 2 exam?
It suits practitioners who need a working command of radiation safety and regulation around sealed sources and radiation equipment: industrial radiographers and their supervisors, radiation protection officers, source custodians, transport staff, and inspectors. If your role involves authorising, performing, or overseeing exposures, the syllabus maps closely to your daily decisions.
What is the exam format?
Expect a multiple-choice, closed-book computer-based exam, but confirm this with the official body. Questions are applied rather than purely definitional, so you must choose the correct action, dose limit, classification, or notification route in a described situation. Some items combine two domains, for example a transport package problem that also raises emergency response duties.
How long is the exam and how many questions are there?
Those figures are set by the certifying organisation and are revised periodically, so check its official website for the current question count and time allowance. Do not plan your pacing from forum posts. As a practical rule for any timed technical exam, practise answering applied items in under a minute each so you have time to revisit flagged calculations.
How difficult is it?
Candidates with field experience usually find the operational and emergency sections intuitive but struggle with dose calculations, package categories, and the precise wording of regulatory duties. Those without hands-on radiography experience find the reverse. Difficulty is less about obscure physics than about knowing which rule applies and who must be notified, and in what timeframe.
In what order should I study the domains?
Start with radiation protection fundamentals and the regulatory framework, because every other domain depends on dose limits, justification, and licensing concepts. Then study sources and equipment, followed by radiography operations. Finish with emergency response, transport and storage, and quality management, which are easier once you understand the underlying hazards and controls.
What are the most common failure modes?
Mixing up dose limits for workers, trainees, and the public; confusing transport package types and their activity limits; forgetting notification and record-keeping obligations; and treating emergency response as common sense rather than a defined sequence. Another frequent error is answering what is technically effective instead of what the regulation requires.
Can I retake the exam if I fail?
Retake rules, waiting periods, and any limits on attempts are set by the certifying body and can change, so confirm them on its official site before you book. Practically, use any score report to identify weak domains and rebuild those areas before rebooking rather than repeating the same preparation.
How should I prepare in the final weeks?
Shift from reading to retrieval. Work scenario questions aloud, justify each answer against a regulation or protection principle, and note where your reasoning was right but the cited basis was wrong. Review emergency procedures step by step and rehearse the notification chain. Confirm exam-day logistics, permitted materials, and identification requirements with the official body in advance.
