Question: I was told not be around people for a few days, after having my thyroid x-rayed. I was told I would be radioactive; is this true?

You are not radioactive after having a x-ray, but it sounds as if you had a nuclear medicine study. We don't x-ray the thyroid gland, as this gland cannot be seen with x-ray alone. We used ultrasound (which involves no radiation) and nuclear medicine studies (which requires an injection of a radioisotope or swallowing a pill with a radiotracer). The following is taken from a patient education site, regarding thyroid uptake and scans. You can also visit the site, to review the procedure, to ensure this is actually the study you had..... "Through the natural process of radioactive decay, the small amount of radiotracer in your body will lose its radioactivity over time. In many cases, the radioactivity will dissipate over the first 24 hours following the test and pass out of your body through your urine or stool. You may be instructed to take special precautions after urinating, to flush the toilet twice and to wash your hands thoroughly. You should also drink plenty of water to help flush the radioactive material out of your body." http://www.radiologyinfo.org/en/info.cfm... "No isolation or special precautions are needed after a thyroid scan." http://www.healthatoz.com/healthatoz/Ato... http://www.radiologyinfo.org/en/info.cfm...

To answer your question first, not enough for the untrained eye to spot but the bottle will give you away so change it. X-rays are absorbed, transmitted and scattered when an x-ray is given and the material dictates the amount of each. A grid is used to limit the scattering and thus blur in the x-ray on film and the video image. Since security uses a very low amount of x-ray and video screen to look at your stuff and it passes pretty fast they will not be able to distiguish the contrast between water and alcohol. Now a very trained eye (radiologist) would pick up on the contrast difference and then might want a second look but I doubt you have that to worry about. A good security program would train its people by looking at different objects under x-ray to see the contrast outline difference. Eventhough they could not tell between H20 and alcohol they could at least want you to open your bag then you are screwed. I really don't think you have anything to worry about. Its just booze not a gun, explosives, a knife, or liquids that can be combined to make an explosive or toxic gas etc. X- GE medical systems engineer

Alcohol has a lower specific gravity than water, but Xrays aren't able to see that difference. It would just show up as non-specific fluid.

I definitely think u r not radioactive after being x-rayed. Who told u that? Definitely not a doctor. Perhaps the person who told u that meant it as a joke. And thyroid is usually not x-rayed, but usually using ultrasound. This is as far as my knowledge. No need to worry. It's a joke. U r not radioactive. It doesn't make sense. Hope it helps

Spencer Originally Answered: Is Hiroshima and Nagasaki still radioactive?
The radiation itself was momentary however the neutron burst would've activated and debris into their radioactive isotopes with varying half lifes. Some of these isotopes are particularly dangerous as they are variations of elements our body naturally uses so the isotopes are brought into close proximity with our DNA causing damage. This is why iodine tablets were part of the "survival kit", by being saturated with known iodine, you would not absorb the radioactive iodine and it would not come into close enough proximity to harm you. Most of the other elements are easily filtered out and kept at a safe distance with simple barriers and air gaps. Iodine-131 has a half life of 8 days so it's only a problem for a few months at the most. Other isotopes like Thorium-232 have a half life of 14 billion years but fortunately these heavier elements are not the majority of the radioactive fallout, remember, the heavier elements must be in the debris in order to be activated into isotopes by the neutron burst and these elements only exist in trace amounts to begin with. There will always be residual radioactivity but the majority drops off quickly after the event. Yes, both Hiroshima and Nagasaki are still radioactive but no, it's not dangerous to be a tourist there as the bioavailable isotopes had very short half lives. It's often believed that the bombs were air detonated to maximize the area affected but that was not the case. An airburst minimizes the amount of debris drawn into the fireball and hence minimizes the radioactive fallout. Remember, they were anticipating putting soldiers at ground zero within days of atomic blasts. Note, the legs of your kitchen table are probably radioactive too. Ever since X-ray machines and smoke detectors have been scrapped, various radioactive materials have made it's way into the recycled metal to the point where virtually all refined metals are now radioactive. To make an accurate and sensitive geiger counter now requires salvaging metal from a WWII shipwreck.

This Site Might Help You. RE: Is Hiroshima and Nagasaki still radioactive? I heard nuclear waste has a half life of 1000 years or something like that. So does that mean those cities are radioactive.
