I am board certified but with less than 1 year experience post residency. I could not find a job. Even though lots of ads are there, it does not really matter because either those people who posts the ads already have persons in their heads or it requires at least 5 year experience. Medical physics is not a real physics. People with many other backgrounds can pick it up easily. That's why it is difficult for new people finding job I really regret to have studied medical physics and got phd and board certificate. I hate medical physics. Medical physics working in cancer centres just perform routine work, very boring.
