How much you make as a Radiology Technicican is dependent upon many factors.It really depends on whether your working in a hospital or a doctors office, how experienced you are, the shift you are working and many other factors. If I had to give you a number I'd say $18-$20 is pretty good.
One other thing I need to mention since you specified an associates degree. Many people wonder if there's a difference between having an associates and having a bachelors. If you want to get into management or teaching a bachelors would be good but in terms of working as a tech all that matters is your certification, you won't make more by having a bachelors degree.
