the greatest radiation exposure risk comes out from Fukushima fallout err the polonium naturally found in seafood but from doctors this was the study that really shook things up estimated risks of radiation induced fatal cancer from pediatric cat scans which concluded that the best available risk estimates suggest that pediatric CT scans will result in significantly increased lifetime cancer risk how increased well in the United States of the approximately 600,000 abdominal a head CT scans annually performed in children under the age 15 500 of these individuals might ultimately not just get cancer but died from cancer attributable to that cat scan radiation in response to this revelation the editor-in-chief of the leading radiology journal admitted that radiologists may have not been watching out for children these estimates were based on data from Japanese atomic bomb survivors in terms of how many cancer deaths one can expect from you know what kind of radiation dose but you know there’s never been a study actually documenting the excess cancers until now turns out the x-rays released by cat scanners might be twice as carcinogenic as the high-energy gamma rays released from the atomic bombs a few CT scans may nearly triple the risk of brain tumors in leukemia in children other studies are being performed around the world to quantify the risk and should be out in the next few years until then what can we do well first of all we should only get x-rays when absolutely necessary good evidence suggests that between a fifth and a half of cats cats aren’t necessarily aren’t necessary at all they could be replaced with another type of imaging or just not done period that’s a lot of added cancer risk for no added benefit now this kind of cat scan okay but this kind carries risk the risk of developing cancer after a single CT scan may be as high as one and a hundred for a baby girl it can take years for cancer to develop so that’s why the risk is lower in the elderly since they have fewer years to live the diagnostic medical radiation dealt out in one year is estimated to cause 2,800 breast cancers among women in the United States and 25 thousand or so other cancers that’s doctors causing cancer one chest CT scan is like getting 400 chest x-rays and a stress test part scan can be like getting over a thousand x-rays doctors need to communicate the risks of these procedures for example the risk of a chest CT is like the risk of having a car crash during 2500 miles of highway driving or of smoking 700 cigarettes you pick up a pack of cigarettes and there’s a warning label right but then you go in for a thallium heart scan and no one Minds telling you that the risk corresponds to smoking 1,400 cigarettes one in every 270 middle-aged women they get an angiogram may get cancer because of that one test the best way to avoid the risks of radiation scans is the same way to best avoid the risks of medication living and eating healthy enough to help avoid the need for them in the first place you you
