Guest guest Posted December 18, 2009 Report Share Posted December 18, 2009 No, a little isn't going to kill you. However, yesterday I believe there was an article in the news that a study was done and the medical profession is becoming alarmed at the preponderance of radiation from xrays, ct scans and nuclear test material that has increased a great deal. The radiation does stay in your body, and it is cumulative. They are warning people to stay away from radiation from testing sources if possible, and get other kinds of testing like MRIs and ultrasounds. http://www.examiner.com/x-7160-Sacramento-Nutrition-Examiner~y2009m12d16-CT-Scan\ s-excess-radiation-and-cancer-predictions-latest-news Roni <>Just because something isn't seen doesn't mean it's not there<> > > From: susansbook <susansbook@... <mailto:susansbook%40>> > Subject: Well, I had it done... > hypothyroidism > <mailto:hypothyroidism%40> > Date: Wednesday, December 16, 2009, 6:02 PM > > 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.

The issue is CT scans, since these require multiple exposures. Regular X-rays result in less than 1% of the exposures from 30 years ago, and the trend is downward. CT scans are different. Nuclear medicine procedures are also another matter, since the exposure depends on many variables, including the concentration of the nuclide in a specific organ. Thyroid uptake tests fall in that category, in which case the whole body dose is pretty minimal. With these, radioactive material does stay in the body for awhile, but NOT the radiation. > The radiation does stay in your body, and it is cumulative. Radiation from a CT scan absolutely, unequivocally does NOT stay in the body after exposure. The damage is cumulative, but only if the rate of exposure is high. The body seems to repair damage that occurs at a low enough rate. This is why these estimates are exaggerated. > ... They are warning people to stay away from radiation from testing sources if > possible, and get other kinds of testing like MRIs and ultrasounds. That has always been good advice, except for three influences: 1. If the risk of missing the diagnosis is high, it could outweigh the risk of the CT scan. This is something doctors are supposed to calculate prior to ordering a CT scan. 2. MRIs cost a lot more than CT scans, so diagnostic procedure choices could be catering to insurance rates. 3. The hospital may be trying to pay for new equipment and pressure doctors to use the newest system. Chuck Quote Link to comment Share on other sites More sharing options...
Guest guest Posted December 18, 2009 Report Share Posted December 18, 2009 Believe me, if there is a need for a type of xray test I have done it. Like having a mammogram diagnostic xray after a screening xray, because I had pain. If something is warranted it's warranted, and we take our chances. I will try to avoid xrays and ct scans and nuclear testing if at all possible though. 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 It seems to me that 1-2 rems would have 20% of the negative effect of 5-10 rems. 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 Question: When flying on a commercial jet airliner at high altitudes (i.e., transcontinental or transatlantic), what is the x-ray exposure per hour? Answer: The radiation exposure to passengers and crew in high-flying aircraft is caused not only by x rays (photons) but also by a variety of energetic particles such as neutrons, protons, electrons, muons, and pions. These radiation types are produced as a result of the interaction with the Earth's atmosphere of high-energy particles (primarily protons and alpha particles) that come from a variety of cosmic sources in our galaxy, with a lesser contribution from our own sun. The galactic component of this incoming cosmic radiation is always present; the solar contribution varies in intensity over an approximately 11-year cycle. In fact, the galactic component is greatest at solar minimum and is reduced at solar maximum by solar particle interactions with irregularities in the magnetic field associated with the " solar wind. " Additionally, there is a significant variation of dose rate with altitude and to a lesser extent with geomagnetic latitude. During the last period of " solar minimum, " at an altitude of 30,000 feet, the dose rate was about 4 μSv per hour at the latitudes of North America and Western Europe. During solar maximum, which is occurring now, the dose rate fell to around 3 μSv per hour. For the higher altitude of 40,000 feet, the dose rates were about 8μSv per hour at solar minimum and now are about 6.5 μSv per hour. To put this into perspective, the legal value of " maximum permissible dose " for members of the public exposed to radiation originating from ground-based industrial or medical facilities is 1,000 μSv per year. So an airline passenger flying at an average altitude of 35,000 feet for a period of about 160 hours (75,000 miles) during solar minimum would receive an exposure at about the limit of the current acceptable level. Of course, most people who fly 75,000 miles a year or more do so because of their professional responsibilities as business travelers. It is my contention that the almost 450,000 individuals in the United States who fall into that category should be classified formally as occupationally exposed workers and that they should receive appropriate education about their exposures, particularly if they may be, or are about to become, pregnant. In addition to the general cosmic-ray " background " discussed above, there are rare solar particle events ( " solar storms " ) that can significantly elevate the dose rates at airliner altitudes. The National Oceanic and Atmospheric Administration (NOAA) estimates that in an 11-year solar cycle there could be up to three events that might produce a dose rate of up to 200 μSv per hour for a few hours at airliner altitudes. The most recent significant particle event occurred on 14 July 2000. Although an exact value of the maximum dose rate has not yet been established, my estimate is that it was at least 50 μSv per hour extending over the relatively long period of almost a full day. J.

Guest guest Posted December 18, 2009 Report Share Posted December 18, 2009 There are two more effective options, thermography and an MRI. The first is more likely to detect cancer before it forms any lumps and the second is more likely to detect cancerous lumps. Mammogram Test Alternatives http://answers.google.com/answers/threadview/id/449672.html One may have to pay more in medical fees but one can avoid mammograms. On a different note, I recall a survey of male doctors that asked if they would recommend that their wives get a mammogram. The response was overwhelmingly no. Speaks volumes.

Guest guest Posted December 18, 2009 Report Share Posted December 18, 2009 My concern with this and other radiation and nuclear testing is only that there is so much of this that we do get normally, the less we can avoid the better. The atom bomb radiation caused cancer in people that weren't anywhere near it. We all got a dose of radiation from Chenoble and Three Mile Island, airplane flights, etc. If one of the tests is absolutely necessary than it is and I would get it. If I can get another test without it, I will do that. Some doctors offer these tests as the only way to get it done, and in many instances there are other options.
