A radiologic technologist is the same as a x ray technician because they work with the radiologist to try and get the best imaging picture to help diagnose a patients illness but they do not make the diagnosis. In many states a radiologic technologist would have to make sure that their license is up to date.
The process for renewing your license usually takes about two to three weeks and there is also a fee that you must pay to renew your license which depends on whether your active currently or not. If you do no not renew it within the active period the cost of the fee triples so you will want to make sure you keep your license active so you do not have to pay out extra money in the long run. If you let your license run inactive for ten or more years it become null and void and you would be required to go back and take the test.
The need for radiologic technologists is rapidly growing with more expectations for jobs to keep increasing. So this is a highly valuable career that you can expect to be able to graduate and find work much more easily then any other professions. And since the work environment has you working in hospitals and doctors offices it would be a well rewarding career for someone looking for a job that is steady and provides a secure career future.
