Description of Voss Training Courses

NRRPT Exam Review Class - an intensive 5-day class designed to prepare the candidate to successfully pass the NRRPT Exam. The course concentrates on the basic tools the candidate needs to successfully pass the NRRPT exam. This class is also an excellent refresher class.

The 150 question NRRPT exam covers broad-based radiation protection knowledge of; Accelerators, University Health Physics, Medical Health Physics, Power Reactors, Government Radiological Facilities, Radioactive Waste Disposal, Transportation of Radioactive Material, Fundamentals, and Regulatory Requirements. Three general categories in the exam are; Applied Radiation Protection, Detection and Measurements, and Fundamentals.

Applied Radiation Protection is subdivided into Survey and Inspections, Emergency Preparedness, Evaluating Internal and External Exposures and Controls, Prescribed Dosimetry and Radiation Equipment, Contamination Control, Radioactive Material Control and Transportation, Guides and Regulations, and Procedures and Programs (ALARA).

Detection and Measurement is subdivided into Analytical Methods, Instrument Calibration and Maintenance, Personnel Dosimetry, and Equipment Operation.

Fundamentals is subdivided into Sources of Radiation, Biological Effects, Mathematics, Chemistry, Physics, and Units and Terminology.

We concentrate on the knowledge and skill sets the NRRPT has established for exam candidates. Our training test bank provides 9 individual full exams (1,350 questions and answers) for the attendees to practice. Each of the questions in our test bank explains why each correct answer is correct and why each incorrect answer is incorrect. The attendees will see WHY the correct answer is correct and not simply A or B or C or D or E. And the attendees also see WHY answers A, B, C, D, or E is NOT correct. Our training and our comprehensive question test bank ensures the attendee will have the knowledge and skills to pass the NRRPT exam. Rules of thumb and simplified mathematics for problem solving are covered in depth.
