Radiation from medical imaging: Just how dangerous is it?    

radiationAdvances in medical technology are sometimes a double-edged sword. A prime example? Medical scans that use radiation to peer into human bodies.

X-rays aren’t the only culprit. In fact, far greater doses of radiation are involved in CT scans, PET scans, fluoroscopy and nuclear medicine studies (though these doses are still considered low when compared to high levels of exposure from events such as Hiroshima/Nagasaki and Chernobyl.) This ionizing radiation damages human DNA and disrupts normal cell functioning.

It has long been thought that even extremely low levels of radiation increase your lifetime risk of cancer. However, a growing body of research casts doubt on this assumption – with far-reaching implications for medical imaging.
