I'm a former X-ray tech. The job SUCKED! It took 2 years of training, and I was rewarded with a low paying/crappy hour job that involved things like:
-Cleaning up barium enemas (if you saw anyone over 65 getting a lower GI, you would crinch because you knew they couldn't hold it)
-smelly homeless people in the ER. Some of those guys would take their shoes off and you would actually throw up. This isn't "it smelled bad and I'm exagerating." I'm talking it would initiate a gag reflex on anyone on the floor bad.
-Constantly demanded to do things that you really don't think you're qualified to do. I had to hold clamps during heart surgery, plug up bullet holes with my fingers, administer IV drips, do nurse duties and get paid 1/4 their pay...the list was endless
-Figure on hours like 2pm-midnight one week, then 2am-10am the next week, and then 8am-8pm several days to fill in, etc. You don't get a cushy day shift job until you get at least 10 years in.
-Pay scale is awful for what you do. Starting pay is usually in the low-mid $20's, and goes up to the mid $30's after several years (with an AS degree. A BS degree pays more, but most people go to administrative positions with a BS degree).
The fun parts of the job however included making copies of x-rays when people stuffed things into various body cavities, hanging out with hot nurses, and getting to sleep on comfy beds when it's slow. Oh, and free food in the cafeteria was cool (they had some good stuff!).
Worst job I've ever had all in all though.
