Normal functioning of the kidney, brain, liver, heart, and other systems can be affected by uranium exposure, because, besides being weakly radioactive, uranium is a toxic metal. Uranium is also a reproductive toxicant. Radiological effects are generally local because alpha radiation, the primary form of 238U decay, has a very short range, and will not penetrate skin. Uranyl (UO2+
2) ions, such as from uranium trioxide or uranyl nitrate and other hexavalent uranium compounds, have been shown to cause birth defects and immune system damage in laboratory animals. While the CDC has published one study that no human cancer has been seen as a result of exposure to natural or depleted uranium, exposure to uranium and its decay products, especially radon, are widely known and significant health threats. Exposure to strontium-90, iodine-131, and other fission products is unrelated to uranium exposure, but may result from medical procedures or exposure to spent reactor fuel or fallout from nuclear weapons. Although accidental inhalation exposure to a high concentration of uranium hexafluoride has resulted in human fatalities, those deaths were associated with the generation of highly toxic hydrofluoric acid and uranyl fluoride rather than with uranium itself. Finely divided uranium metal presents a fire hazard because uranium is pyrophoric; small grains will ignite spontaneously in air at room temperature.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What type of uranium compounds are uranium trioxide and uranyl nitrate?
Ah, so.. hexavalent

Himachal has a rich heritage of handicrafts. These include woolen and pashmina shawls, carpets, silver and metal ware, embroidered chappals, grass shoes, Kangra and Gompa style paintings, wood work, horse-hair bangles, wooden and metal utensils and various other house hold items. These aesthetic and tasteful handicrafts declined under competition from machine made goods and also because of lack of marketing facilities. But now the demand for handicrafts has increased within and outside the country.

Ah, so.. unanswerable

It was also the exclusive carrier of Canadian Curling Association events during the 20042005 season. Due to disappointing results and fan outrage over many draws being carried on CBC Country Canada (now called Cottage Life Television, the association tried to cancel its multiyear deal with the CBC signed in 2004. After the CBC threatened legal action, both sides eventually came to an agreement under which early-round rights reverted to TSN. On June 15, 2006, the CCA announced that TSN would obtain exclusive rights to curling broadcasts in Canada as of the 2008-09 season, shutting the CBC out of the championship weekend for the first time in 40-plus years.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): After numerous court battles, the CBC agreed to transfer exclusive rights to curling events to what broadcast station?
Ah, so..
unanswerable
