There is a chemical that is mined in the states that once refined, is used to make EVERYTHING man made white.

My boyfriend is heavily considering going to school for radiography to be an X-ray tech. If you have experience in the field, I'm really interested in hearing what your annual salary is, your average hours put in a week, and how rough you considered the schooling involved!

Thank You!
