The Occupational Internal Dosimetry Online Training course contains 21 modules and four problem sets designed to provide course participants with a thorough understanding of current methods for determining radiation doses resulting from intakes of radioactive materials by workers. The course covers the basic concepts and principles of internal dose assessments, and describes the ICRP internal dosimetry systems and models currently in use in the United States and internationally. Bioassay methods (both direct and indirect) are reviewed and bioassay interpretation is discussed in detail. Regulations and regulatory guidance is discussed, including the design of bioassay programs and methods for demonstrating regulatory compliance. Finally, quality assurance and methods for program evaluation are covered. Throughout the course, students work detailed example problems covering all aspects of internal dose assessment.

It is self-paced and can be completed as time allows. To complete the course, you will be required to pass an exam. A passing score is 70 out of 100. You will have three attempts to successfully complete the exam. A certificate of completion will be provided upon successful completion of the exam. Course materials are available on the ORAU PTP Learning Management System (LMS).

PTP instructors will be available via email, phone, or Microsoft Teams to answer questions and provide assistance when needed.
