Guest guest Posted December 17, 2009 Report Share Posted December 17, 2009 and I was a wreck for the first fifteen minutes... but I calmed down. They won't get me to do the dye ever again unless it's a total emergency and there is no other choice. I am just freaking out that I did it. I did great though. I handled the treadmill wonderfully, stayed in breath and was on it the whole time. At the end I sure was getting tired of trying to keep myself standing straight on that incline. Not used to that at all. I'm not sure what the test will reveal over all, but the technician said that I was in pretty darned good shape to keep up with it and talk and laugh the whole time. I did get dizzy once it stopped, but I always do when I'm on something that is moving and suddenly I'm standing still. Wigs out my balance a little. Thanks for all the advice. I didn't get the chance to take anything before I went in but I downed a bunch of Vit. C and ate a bunch of carrots and yams when I got home. I have no idea why I wanted those so much, but I kept shoveling them in. I guess it may have been for the carotene. (Is that one of the things you use to help with the dye removal from the body?) Anyway, thanks again, everyone. I appreciate it and I'm going to copy all the info and do some research and educate myself much more before something like this ever has to come up again.

Guest guest Posted December 17, 2009 Report Share Posted December 17, 2009 Well, glad it's over and you did so well. However, the nuclear material cannot be washed out of your body with food or anything else. It will stay there for years. From here on in, make every effort to avoid radiation of any type, including xrays and especially CT scans. Each year that you avoid radiation, will be a year that your body has less of it. By the way, the unit of measure is called a rad.

There is no residual radiation from an X-ray or CT scan. The problem with the CT scan is that it takes a lot of radiation to construct one 3D image. > ...

The rad is 1 erg/gram, where the current standard unit is the Gray, or 1 joule/kg. For assessing risk exposure, you really need to account for relative biological effectiveness (RBE), in which case the appropriate unit is the Sievert = RBE x Grays.

Guest guest Posted December 17, 2009 Report Share Posted December 17, 2009 You're right about the rad being obsolete. Now you know how far back I go. Here's an article which discusses cumulative radiation. http://www.lef.org/magazine/mag2008/mar2008_Avoiding-The-Radiation-Dangers-of-CA\ T-Scans_01.htm Roni <>Just because something isn't seen doesn't mean it's not there<> > ...

Guest guest Posted December 18, 2009 Report Share Posted December 18, 2009 Roni, I'm under the impression that the half life of the radionuclide used is 2 or 3 days. Besides it's such a low dose that it is considered virtually harmless. I think it's on the order of 1 or 2 rems, and no adverse effects are thought to occur from less than 5 to 10 rems. OTOH I'm certainly far from being an expert on the subject. But I do know that we evolved in an environment containing radiation, so a little isn't going to kill you. .. .. > Posted by: " Roni Molin " matchermaam@... > <mailto:matchermaam@...?Subject=%20Re%3A%20Well%2C%20I%20had%20it%20done%2\ E%2E%2E> > matchermaam <matchermaam> > > > Wed Dec 16, 2009 6:24 pm (PST) > > > > Well, glad it's over and you did so well.

Guest guest Posted December 18, 2009 Report Share Posted December 18, 2009 In the stress test the concentration of radiation is very small to start with, and it has a half life of a couple of days. Besides that your kidneys [and liver?] probably start removing the material immediately. And if they don't after two days the level has dropped to 1/2 of the original very low dose, and after about 4 days to 1/4. Run this out for 10 half lives of an already low dose and see how much remains. As Chuck has indicated [i think] this procedure isn't the one that is any major part of the concern about excessive radiation. I'm not saying there isn't ANY; just that there are so many more sources that should be of a greater concern. When you weigh the cost/benefit there's next to nothing on the cost side of the ledger [health wise; not financially].

The balance of your post is very interesting, although the units of exposure are not familiar to me [but truthfully, I'm not that knowledgeable about the old units either. I just know that higher is bad]. Generally it bears out my contention that the concern about the exposure from a nuclear stress test should virtually disappear into the environmental " background noise " of radiation exposure. That's not true for all of the common tests, which I guess is one of Roni's points. .. .. > > On the other hand, I recall a study where towns in England that had > higher levels of background radiation have longer lifespans. > > On another note, it occurred to me that people who travel regularly in > aircraft will get a much higher exposure than most medical procedures. > On a quick search, I turned up this: > > http://www.hps.org/publicinformation/ate/q444.html > <http://www.hps.org/publicinformation/ate/q444.html> > > Question: > When flying on a commercial jet airliner at high altitudes (i.e., > transcontinental or transatlantic) > , what is the x-ray exposure per hour?
