Radiation Physics, Biology, and Safety


The following enhanced podcasts include images. Save them to your computer (right-click→Save As...). (Left-clicking on the podcast links will only play the audio portion with no images.)

Consider these questions as you study radiation physics:

What is radiation? What are x-rays? How are x-rays produced? How do x-rays interact with matter?

Be able to perform the following as you study radiation biology and safety:

Discuss the biological effects of ionizing radiation. Discuss how to protect your self, staff, and patients from ionizing radiation.

What would you do if your patient was pregnant? Would you still perform a radiographic study?
