How old do you have to be to waitress in CT?

Ct scans and radiation risk and that new study and 80 millions ct scans in usa do we need to worry?

• in 2007 70 millions ct scans performed in usa last year 100 million ct scan performed in usa so i thing all of us got a ct scan in our life even me i got one now we all khnow about that study that talkes about how the radiation we got from ct scan can give us cancer [[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[... Brenner and Hall said the dose of radiation delivered in one or two CT scans is roughly equivalent to doses received by atomic bomb survivors in Japan who were 2 miles away from the blast sites when the bombs hit. Studies showing a rise in cancers among these survivors decades after the atomic blasts led to their estimate of risk among people having CT scans today [[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[... so can we Compare the radiation from the nuclear bomb to the radiation from a single ct scan so can we said that all of us at risk of cancer from ct scan we got in our life due accident or some symptoms [[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[... Based on current usage, Brenner and Columbia colleague Eric J. Hall, PhD, estimate that within two or three decades, 1.5% to 2% of all cancers in the U.S. will be caused by exposure to CT scans [[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[... lets say for example from a head ct with and without contrast we got i thing 2 msv im not sure so do the people in japan got that amount of radiation i dont think so i thing they got more do you think that study is correct

• Answer:

  I would not say this study is "correct" but it correlates to other studies which recommend avoiding numerous CT scans throughout your lifetime because radiation has a cumulative effect and it can take years before any symptoms of cancer may appear which then makes it more difficult to prove a direct cause/effect that a particular cancer was caused by a CT scan.
