Because enriched uranium is a radioactive substance, there has been concern about the possible health effects of depleted uranium. While depleted uranium does not have the level of radioactivity of enriched uranium, some experts fear that itmight cause health problems. The Department of Defense and ...
Lead is heavier, but it is so soft that it is useless in a penetrator -- lead would deform or disintegrate when the bomb hits the target. One material that is both extremely strong and extremely dense is depleted uranium. DU is the material of choice for penetrating weapons because of ...
Soon after Röntgen's discovery, a French scientist named Henri Becquerel attempted to figure out where X-rays came from, and in the process found that uranium emitted a powerful "ray." Marie Curie based her doctoral research on Becquerel's findings, which led to her discovery of radium [...
Why were the proton and electron discovered before the neutron? What is weight in physical science? How much uranium is in the human body? What prevents a neutron star from collapsing? What happens to the neutron-proton ratio in alpha decay? How does the cyclotron shoot a neutron into U-23...
The following chemical equation represents the radioactive decay of uranium. 23592U arrow 23190Th + 42He Use the nuclear model of the atom to explain how this reaction is possible. Radium-224 has a half-life of 3.66 days. What was the mass of the original sample of radium-224 if 0.0500...
This illustration shows nuclear fission of uranium-235. Nuclear Power Nuclear bombs involve the forces — strong and weak — that hold the nucleus of an atom together, especially atoms with unstable nuclei. There are two basic ways that nuclear energy can be released from an atom. In nuclear...
One particular characteristic of commodities is that they are produced and traded in large quantities, guaranteeing a global supply and enough liquidity for the market. There are four main types of commodities: Energy: these commodities include crude oil, electricity, natural gas, coal, uranium, gas...
How does it affect us? What do they tell us about the world and the universe that we don?t know. It?s all fascinating to me, and I love to get time in the lab or the field to satisfy my curiosity in this arena. But, alas, the hierarchy of human needs puts safety first. And ...
“UK forces used about 1.9 metric tons of depleted uranium ammunition in the Iraq war in 2003,” the Defense Secretary Liam Fox told parliament on 22 July. A range of toxic “antipersonnel” weapons, such as cluster bombs, was employed by British and American forces. We know all of this...
Use the concept of melting point to explain why some plastics cannot be used to microwave food. Use the concept of melting point to explain why some plastics can't be used to microwave food. Explain why the mining of uranium often pollutes the local environment. Why does...
