What is the amount of radiation you are exposed to from a dental xray?

1-2 hrs in sun: 4 radiographs (x-rays) are approximately equivalent to 1-2 hours in the sun without sunscreen.

Radiation : For a panoramic dental X-ray, total effective dose is about 0.01 mSv.

Very low!: It is equivalent to background radiation dose from living on this planet for 10 days. See link for dose equivalents https://www.radiologyinfo.org/en/pdf/safety-xray.pdf
