X-ray classes are much harder than my MA classes.  In the past three weeks I've learned how to take x-rays of the skull and face and all kinds of stuff about radiation safety.  Guys make sure that if you ever get x-rays that they give you the shielding for your gonads, it's very important.  We are working on the cervical and thoracic spin this week and I have a mid-term on Friday and a test on safety and the upper spine tomorrow.
