Introduction to Radiation Safety Online Training

Online continuing education course on safe handling of radioactive materials


The use of radionuclides and radiation sources in industry, medicine, and education continues to create a need for persons trained in their safe use.

The American Academy of Health Physics grants 24 Continuing Education Credits for completion of this course.

Course description

The Introduction to Radiation Safety online training course contains 14 modules designed to provide an introduction to the basic science behind radiation safety and to common applications of radiation safety principles. Topics include a description of common radiation sources, interactions of radiation with matter, biological effects, detection, and measurement. Videos emphasize radiation detection and measurement techniques using both fixed and portable instrumentation.

A list of the modules included in the course is provided below along with instructions about the registration process. This course is the equivalent of taking only the lecture component of the instructor-led course at the PTP training facility. PTP instructors will be available via email, phone, or Microsoft Teams to answer questions and provide assistance when needed.

Target audience

This course is designed for individuals who are new to working around sources of radiation and those who are interested in reinforcing their basic understanding of radiation safety and measurements.


$1,197 – Tuition includes access to the course materials via the ORAU Learning Management System (LMS).
