Is the radiation from our x-ray machine harmful?

At our office, we take x-rays to see clear and precise anatomy which aids our doctor in diagnosing. Is the radiation emitted from the machine harmful? Like most things, in excess, the radiation would eventually become harmful. Thankfully we have the newest x-ray machine and the radiation that it uses to take one x-ray is a bit less than the radiation you may receive from spending a day out in the sun.
