All things are radiocative. The only thing in this universe that isn't radioactive is the small amount of hydrogen that scientists have refined to not be radiocative.\n\nThis "radioactivity of everything" is what we call the background radiation level. It varies from place to place but everywhere has a background radiation level, and the insides of people or other organisms are no exception.\n\nFood is radiocative because the ground and air it came from is radiocative.\n\nThe ground is radioactive because the matter the Earth was made of came from a supernova. And supernova is just a really, really big atomic bomb.\n\nThe air is radioactive partly because of that supernova but mostly because the sun is also basically a really big nuclear bomb. On the ground we are protected from all the worst radaiation that bomb puts out. In the upper atmosphere the air is not protected. It gets zapped with masive amounts of radiation every day and is fairly radioactive as a result.\n\nWhen plants take minerals out of the soil those minerals are slightly radioactive from the supernova that created the Earth. When plants take carbon out of the air that carbon is radioactive from being zapped by nuclear radiatioon from the sun. When the plants use those things to build more plants the plants become radioactive. When animals eat the radioactive plants and use that material to build animal bodies the animals become radicoative.\n\nAnd when people eat radiocative plants and animals our bodies become radiocative.\n\nEverything in the universe is radiocative, even us. The only thing that varies is how radioactive they are.\n\nYoumay be interested in the link below. It explains how all food plants and all animals are radiocative, and how this  radiactivity of all living things forms the basis of radiocarbon dating techniques.

No, it comes from inside the TV. Only a tiny fraction is from cosmic radiation. PS, the number of points i have from the time of answering right now, is 24 less than my year of birth.

I GOT THIS FROM WIKIPEDIA\n\nPlutonium is a radioactive, metallic, chemical element. It has the symbol Pu and the atomic number 94. It is the element used in most modern nuclear weapons. The most important isotope of plutonium is 239Pu, with a half-life of 24,110 years. It can be made from natural uranium and is fissile. The most stable isotope is 244Pu, with a half-life of about 80 million years, long enough to be found in extremely small quantities in nature. Nuclear materials workers sometimes call it "plute".\n\nThe isotope 239Pu is a key fissile component in modern nuclear weapons, due to its ease of fissioning and availability. The critical mass for an unreflected sphere of plutonium is 16 kg, but through the use of a neutron reflecting tamper the pit of plutonium in a fission bomb is reduced to 10 kg, which is a sphere with a diameter of 10 cm. Complete detonation of plutonium will produce an explosion of 20 kilotons of trinitrotoluene (TNT) per kilogram. (See also nuclear weapon design.)\n\nPlutonium could also be used to manufacture radiological weapons or as a (not particularly deadly) poison.\n\nAll isotopes and compounds of plutonium are toxic and radioactive. While plutonium is sometimes described in media reports as "the most toxic substance known to man", there is general agreement among experts in the field that this is incorrect. As of 2006, there has yet to be a single human death officially attributed to exposure to plutonium itself (with the exception of plutonium-related criticality accidents). Naturally-occurring radium is about 200 times more radiotoxic than plutonium, and some organic toxins like Botulin toxin are still more toxic. Botulin toxin, in particular, has a lethal dose of 300pg/kg, far less than the quantity of plutonium that poses a significant cancer risk. In addition, beta and gamma emitters (including the C-14 and K-40 in nearly all food) can cause cancer on casual contact, which alpha emitters cannot.\n\nWhen taken in by mouth, plutonium is less poisonous (except for risk of causing cancer) than several common substances including caffeine, acetaminophen, some vitamins, pseudoephedrine, and any number of plants and fungi. It is perhaps somewhat more poisonous than pure ethanol, but less so than tobacco; and many illegal drugs (some such as marijuana are negligibly poisonous). From a purely chemical standpoint, it is about as poisonous as lead and other heavy metals. Not surprisingly, it has a metalic taste. [3]\n\nThat said, there is no doubt that plutonium may be extremely dangerous when handled incorrectly. The alpha radiation it emits does not penetrate the skin, but can irradiate internal organs when plutonium is inhaled or ingested. Particularly at risk are the skeleton, whose surface it is likely to be absorbed on, and the liver, where it will collect and become concentrated. Approximately 0.008 microcuries absorbed in bone marrow is the maximum withstandable dose. Anything more is considered toxic. Extremely fine particles of plutonium (on the order of micrograms) can cause lung cancer if inhaled.\n\nOther substances including ricin, botulinum toxin, and tetanus toxin are fatal in doses of (sometimes far) under one milligram, and others (the nerve agents, the amanita toxin, the fugu toxin) are in the range of a few milligrams. As such, plutonium is not unusual in terms of toxicity, even by inhalation. In addition, those substances are fatal in hours to days, whereas plutonium (and other cancer-causing radioactives) give an increased chance of illness decades in the future. Considerably larger amounts may cause acute radiation poisoning and death if ingested or inhaled; however, so far, no human is known to have immediately died because of inhaling or ingesting plutonium and many people have measurable amounts of plutonium in their bodies.\n\nIt must be noted, however, that in contrast to naturally occurring radioisotopes such as radium or C-14, plutonium was man

U could do a comparative analysis of the fat content of your cafeteria foods. Using a fixed mass of each food, extract the fat by mixing with petroleum ether, filtering and collecting the filtrate then heating to drive off the solvent. U could then find the mass of fat that remains (of course you would nned to know the weight of the empty beaker etc bofore anything ws added). Do your percentages, graphs etc. and you are good to go.

Spent nuclear fuel is transported in casks made of a combination of materials. Most designs include a lead, steel, and resin-shielded cylinder, within a stainless steel cask. The lead is the component that shields the most radiation, but the other components prevent physical damage to the container, and chemical reactions between the contents and the container.  The most sophisticated containers also contain a layer of water and depleted uranium to provide additional protection from radiation and heat generated by radioactive materials. The components in these casks will give you a good idea what container vessels should include, both for radiation reduction, and safety. \n\nSee this website, which lists specifications for many container vessels for radioactive material: http://www.trex-center.org/casks.asp\n\nThanks for asking this question. The above website is fascinating.

Irradiated foods are safe.  They are not radioactive (at least not due to the irradiation process) any more than you are after exposure to x-rays (although THEY can be harmful).  The radiation kills bacteria in the food.  \n\nIf irradiation did increase genetic variability it would probably be good for the human race, because, due to advances in medicine, the race is stagnating (genetically, that is) because harmful mutations and deadly diseases no longer always limit life, so the propensity for such mutations and diseases is passed on by reproduction.

Agricultural Applications - radioactive tracers\n\n\nRadioisotopes can be used to help understand chemical and biological processes in plants. This is true for two reasons: 1)radioisotopes are chemically identical with other isotopes of the same element and will be substituted in chemical reactions and 2)radioactive forms of the element can be easily detected with a Geiger counter or other such device.\nExample:\nA solution of phosphate, containing radioactive phosphorus-32, is injected into the root system of a plant. Since phosphorus-32 behaves indentically to that of phosphorus-31, the more common and non-radioactive form of the element, it is used by the plant in the same way. A Geiger counter is then used to detect the movement of the radioactive phosphorus-32 throughout the plant. This information helps scientists understand the detailed mechanism of how plants utilized phosphorus to grow and reproduce.

Carbon-Monoxide is exposed to the meat, but it is not really added to it.\nBananas are made to ripen with ethylene gas.\nSome foods are exposed to nuclear radiation to make them last a long time on the shelf without refrigeration.\n\nAll these are essentially catalysts.  They cause something to happen to the food, but do not stay in the food.  The use of them is not really harmfull in itself, but there could be secondary side effects that are not foreseable.  For example, if meat looks fresher longer, is it possible to purchase meat that is no longer good for consumption because it still looks good?

Ignore the abusive idiot above. He has no idea what he is talking about.\n\n\nThere are lots of different radioactive elements. Some are dangerous but the vast majority are harmless. \n\nYour body and everybody else's is already full of radiocative elements. You are loaded with isotopes like 13Carbon., tritium, 44Calcium and so on. Every living thing that has ever existed on Earth has been losded with those radicoative elements. We've evolved with them from the beginning and as a result they are quite harmles to us in normal doses.\n\nA few unnatural radioactive isotopes are harmful in small doses, and some natural isotopes are dangerous if they are concentrated in the body. But the general answer is that radiocative elements are quite harmless.

<>What, exactly, is the question?  Are you talking about radiation dosimetry?  Can you be just a iota (or ion :) more specific?

YES.\n\nthere are always "isotopes" of common elements in the body such as carbon, nitrogen, oxygen, etc.  present at any given time.\n\nisotopes are chemically identical to their "regular" counterpart elements but differ by one or two neutrons in their atoms.  this makes some isotopes radioactive ( a fact which can be measured as in carbon-14 dating ).  \n\nthe effect of this radiation is exceedingly small and of no concern to life.

helium neon argon krypton xenon radon\nyou probably do not need to know ununoctium because it was just discovered, is radioactive, and radioactively decays in a few seconds.

It's a lie, it's like cell phones causing gas stations to blow up. I work for a package delievery service and we ship optic mice, cell phones and what not all the time, and if something edmits radioactivity it's required to be labeled, even if it doesn't emit the radiation when it's turned off. the only thing you have in ur home that is slightly radioactive is ur smoke detectors.which are class 1, meaning as long as u dont eat them you'll be fine

Francium is radioactive. Its most stable isotope has a half life of only 20 minutes or so. \nThis means that the only Francium present in the earth crust are those atoms that originated from other atoms having decayed. Francium has been detected in Uranium ores but the total quantity present at any time does not exceed 20 grams or so.
