The RAIN scale: A good intention that falls short
Radiation protection specialists agree that clear communication of radiation risks remains a vexing challenge that cannot be solved solely by finding new ways to convey technical information.
Earlier this year, an article in Nuclear News described a new radiation risk communication tool, known as the Radiation Index, or, RAIN (“Let it RAIN: A new approach to radiation communication,” NN, Jan. 2025, p. 36). The authors of the article created the RAIN scale to improve radiation risk communication to the general public who are not well-versed in important aspects of radiation exposures, including radiation dose quantities, units, and values; associated health consequences; and the benefits derived from radiation exposures.
Several resources exist to help those preparing to take the Principles and Practice of Engineering (PE) exam in Nuclear Engineering.
Nuclear PE exam information at NCEES websiteProvides basic information about the exam, including format and registration information.
MyNCEES account loginPortal to creating an account, which is required before signing up for the exam.
Exam specificationDownloadable PDF with an overview of the current topics covered on the exam.
Nuclear PE Exam Preparation Module ProgramProfessional Engineering Examination Committee volunteers have developed a study aid to help prepare engineers who are interested in becoming licensed in nuclear engineering. The Nuclear PE Exam Preparation Module Program aims to be a comprehensive study resource. The video-based online program expands upon the nuclear engineering PE exam study workshop formerly held each June at the ANS Annual Meeting. Each module presents content that follows a list of learning objectives and is aligned with the NCEES nuclear engineering PE exam specifications. Available for purchase online.
ANS Study Guide for the Professional Engineering Examination in Nuclear EngineeringContains information pertaining to PE registration, and the PE Exam knowledge domains, including sample exam questions with solutions. Available for purchase in the ANS Store.
In addition to the ANS educational products, NCEES also offers a Nuclear PE Practice Exam for purchase. The practice exam contains 85 questions from past exams; simulates the format, style, and level of difficulty of exam questions; and provides solutions to enhance the exam taker's understanding for each specification area.
