That’s quite a gift.

However, a lot over a long period is preferable to the same amount at one time. <br/>Thanks for the links. alla

I am sure you can find whole-body CT dose somewhere else if you want.<br/><br/>http://www.virrad.eu.org/public/public/nn_exp.html - a dose from 7 hours trans-atlantic flight. It is about the same as a regular chest X-ray or about 500 times less than an abdomen CT or 100 times less than head CT. <br/><br/>You can figure out whole-body CT on your own.<br/><br/>Oh, and in case you don't know all exposure to radiation adds up. Including all flights and all X-rays and all CTs. Frisbee, here are some links for you:

How would that anecdote even relate?<br/><br/>Non sequiturs for the win, I guess.

I presume quite a bit, if that's the conclusion you reached. Kevin, how many times have you been in court where whether or not you did a test was the crux of the case?
