X-Rays, CT Scans Should Not Be Used Indiscriminately by Arnold Cafe
X-rays produced ionized radiation which also occurs in nature. The effective dose that a human is exposed to is represented by millisievert, a measure of radiation. The average natural exposure amounts to about 2.1 millisievert per year according to Radiation Protection Bureau of Germany. By comparison, a typical patient who undergoes a CT scan (computed tomography or CAT scan) of their head receives an effective dose of 2 or 4 millisievert. While an x-ray exposes the patient to .03 to .01 millisievert this does not mean that patient should take x-ray lightly.
