My wife had an x-ray for her neck on 7th august, 2014. she was pregnant last period date is june 24th june 2014. like to know what is the risk?

Risk very low: There is virtually no risk of harm to your baby from the radiation of the xray test. Your baby should be entirely fine! Good luck!

Low: If the X ray was digital, minimal radiation is exposed to the patient. The patient had a neck X ray which is away from the abdomen which is also reassuring. Had the X ray tech or Radiologists known she was pregnant she should have been shielded with a lead vest to prevent radiation from entering her abdomen. I would not be overly concerned but do talk with your doctor should there be more.

Plain Films?: Virtually no risk, assuming she was given a lead apron. At the time she had the X-ray it's unlikely that she had even yet concieved.

Very low: The neck is far from the pelvis so the amount a radiation there would be minimal. The xray was about the time of ovulation, so multiplication of the cells would not have started yet. I would not worry about it. it is a risk so low that experts are unable to measure it
