radiography

I'm an MD and would like to get my Radiography Supervisor and Operator Permit and want to know if there are any study materials for this exam. Seems to be a paucity of information on this exam online. I was wondering if anyone can help guide me in the right direction. Thank you

Hello, new to the forum so if I post thus in the wrong spot, sorry. Basically I will soon be going back to school (I had to take a year off for personal reasons), and I'll be able to make it financially for a year or two atleast with the job I have now ($10.35 Hourly) but I'm going to need a job...
