Eating uranium is a bad idea, as you probably guessed. Fortunately for people, most uranium that is ingested will pass relatively quickly through the digestive tract, but some may be absorbed. Absorbed uranium poses a hazard, and the amount of uranium ingested would have to be quantified to make an assessment. Breathing uranium, which is a separate issue, is much more hazardous. There will be variations in the amounts of uranium absorbed by the body that will depend on whether the ingested material is uranium metal or whether it is a compound of this actinide. Organic compounds will be absorbed more readily than, say, uranium oxide. Further, the uranium that gets uptaken may be deposited in the bones, the liver or other places. The long term effect of absorbed uranium is that is may be in someone for a while and present a radiation hazard. We know that uranium is radioactive, though weakly. If uranium is deposited in tissue, it may stay there for a while. Radioactive decay will leave decay products, which are also radioactive, stuck within the affected tissue. Anyone who "takes in" uranium may be in store for some body scans to assess damage and what risks the future may hold. It is a challenge to quantify the amount of uranium that a person may have within him, and medical assessment will depend on a good workup.
1. Uranium is a possible polluting agent of the natural environment.2. Uranium is a toxic and a radioactive chemical element.3. Uranium release radium and radon. 4. Radioactive wastes are dangerous and need to be isolated.If working responsibly most of the disadvantages call very limited. And are the major advantages of using uranium especially as nuclear fuel..
Uranium is found in many compounds, though not all these compounds are useful. Notably, however, a uranate is a particular oxide involving uranium in different oxidation states, and is often found in that state in other compounds, such as ammonium diuranate.
Uranium is radioactive, and contamination of water, air or the human system can be fatal or permanently mutate a person or living animal's body, therefore, it is advised not to use uranium and instead use some safer resource.
People use the chemical uranium to help power electricity and power plants.
Rubber is an insolating material. The boots are used to prevent electricity from entering your body. High amounts of electricity have had it's share of deaths worldwide.
Uranium is a very expensive and desired material; having uranium is equivalent with to be rich.
It generates the electrical energy that people need without producing large amounts of CO2 to pollute the atmosphere, and without needing to be fed with large amounts of coal, oil or gas.
Uranium hasn't a biological role.
Uranium is toxic and radioactive for all the people, not specially for pregnant women.
Nobody throws Uranium out. Some people throw their wives or husbands out. Some people let their exclusive golf-club memberships lapse. The nasty by-products of uranium fission, when they are no longer useful, get sent to a giant pool in Idaho. They don't throw the Uranium out either.
People in Niger farm, or mine uranium.

Yes, because Australian people gain many money from uranium.
