you may think we get most radiation from power lines,cell phones,or microwave it's true but we can also get most radiation from medical scans the u.s accounts half of the most advanced procedures tht use radiation,and the average americans dose has grown sixfold over the last couple of decades too much radiation raises the chances of cancer tht risk iz growing because people in evryday situations are getting imaging tests far too often children and young women,who are most vulnerable to radiation harm,sometimes get too much at busy imaging centers tht dnt adjust doses for each parent sizes doctors dnt keep of track of how much radiation are given to patients they order a test not a dose radiation iz a hiden danger u dnt feel it wen u get it and any damage usually dnt show up for years taken indivisually,tests tht use radiation pose little risk PREVENTION:try to go to the imaging center less often or dnt take too much imaging scans be safe
