1. It is estimated that uranium is relatively common in the earth’s crust‚ occurring in amounts of 4 g/metric ton. A metric ton is 1000 kg. At this concentration‚ what mass of uranium is present in 1.0 mg of the earth’s crust? a) 4 nanograms b) 4 micrograms c) 4 milligrams d) 4 × 10–5 g e) 4 centigrams Ans: a) 4 nanograms Page: 1.3‚6 2. In 1928‚ 1.0 g of a new element was isolated from 660 kg of the ore molybdenite

Given the potential dangers of nanotechnology‚ should it be used to lightweight sports equipment? Nanotechnology has an array of uses‚ from sunscreen to sporting equipment. Sports equipment has been vastly innovated by the discovery and application of nanotechnology in recent years. The highest end tennis racquets‚ baseball bats and even racing bicycles all use nanotechnology to combine strength and lightness provided by this technology. Some of the bicycles made with nanotechnology are priced at

waste‚ we are facing the necessity of disposing it. Muller notes that storing nuclear waste will not seem such unacceptable if we evaluate the danger of waste storage in comparison with two other dangers: the danger of the uranium originally mined‚ and the danger of the natural uranium left in the soil. The point is that we cannot guarantee the absolute security‚ but even the nature cannot; and the possible waste leakage is not a kind of danger that cannot be minimized. In order to support his claim

major issue.. What is a nuclear energy? At the heart of the reactor of a nuclear reaction is fission: a neutron moves and strikes an atom of uranium‚ and then the nucleus absorbs the neutron. The core becomes so unstable that it bursts. It is divided into two parts and releases energy. Nuclear fission is not possible with any element. It uses uranium as its atoms are large nuclei unstable easy to divide. This reaction causes a release of energy as heat‚ which will convert water into steam generator

Radioactive decay is the process by which an atomic nucleus of an unstable atom loses energy by emitting ionizing particles (ionizing radiation). There are many different types of radioactive decay (see table below). A decay‚ or loss of energy‚ results when an atom with one type of nucleus‚ called the parent radionuclide‚ transforms to an atom with a nucleus in a different state‚ or to a different nucleus containing different numbers of protons and neutrons. Either of these products is named the

India’s Nuclear Policy The relationship between International Nuclear Regimes and developing nations is a matter of passionate debate. Debate is in process on certain issues like nuclear policy‚ on grand strategies‚ on basic political values etc. It is a debate with implications for our individual and collective existence and raises fundamental question about political preferences‚ approaches and pathways ahead.
