Is there a maximum of X-rays that a person can have?

Answer 1

Yes, there is some maximum of X-rays that a person can have. An X-ray (any X-ray) exposes the person being imaged to some amount of ionizing radiation. Ionizing radiation does some amount of biological damage. But an X-ray, in and of itself, won't "overexpose" an individual to a severe amount of radiation. A half dozen X-rays spaced out over a year given to someone who has needed, say, emergency medical services for injuries, will not usually present a problem.

If you have had an X-ray for any reason, let your medical providor or doctor know when you visit. Certainly you'll need to advise anyone who wishes to give you an X-ray that you've had one or two in the last few months. But it is difficult to get "too much" radiaton from X-rays unless someone is being medically treated with radiation for some reason.

There is no set limit to the number of X-rays someone may get. Is it ten? Or twenty? Who gets twenty X-rays in a year or two? There is a "weight" associated to each X-ray a person gets that might have to be factored in when determining whether someone has had "too much" of this kind of radiation. Unless someone is a radiation worker and/or has had or is undergoing radiation treatment, there is little reason to worry about any dangers from X-ray exposure.
