This two-day Certificate Program introduces radiation therapy shielding design principles and methods that will equip medical physicists with knowledge necessary to prepare successful CNSC submissions and to ensure that the proposed shielding design is optimized in terms of safety and cost. The course is delivered by medical physicists who are highly experienced in modern methods of designing radiation therapy shielding structures. Upon completion of this two-day program, course participants will be able to avoid many of the potential pitfalls in shielding designs. Medical Physics residents will be better prepared for questions related to radiation shielding in residency exams and medical physicists will be better prepared for radiation safety questions on Board exams.

How you learn

You learn in a friendly classroom setting over a period of two days from our knowledgeable Education Team. All of the instructors at this course will be experienced, board-certified medical physicists with strong interest in radiation safety. Instructors do their best to not only convey information, but to ensure that the sessions are interactive and enjoyable for all.

Each day has several learning sessions. Appropriate refreshment breaks are included. Your learning is enhanced by lively discussions and video presentations.

When you complete the course requirements and pass the final exam, you will receive the course Certificate.
