<s>[INST] My doctor suggested a bone density test, but since there is x-ray involved, I am concerned. Should I be? [/INST] There is a small amount of X-ray in a bone density test—;ess than the amount of radiation that you would get flying from California to New York as a result of being closer to the sun. We naturally absorb about 10 uSv (microsievert) of radiation per day if we are living at sea level or 2–3 times that much if we live at higher elevations like Denver (elevation 5,000). A bone density test would give you about 0.4 uSv of radiation. Source: American Bone Health. Link: https://americanbonehealth.org/frequently-asked-questions/. Field: Rheumatology.
