Is most of the energy released by nuclear fission is in the form of gamma rays?
No, most of the energy released by nuclear fission is in the form of kinetic energy of the fission products and neutrons. Gamma rays are also emitted during the process, but they typically make up a smaller proportion of the total energy released.
What organisms use fission method?
Single celled organisms, bacteria and protozoa, reproduce by fission.
The fuel most commonly used in fission reactions is?
The fuel most commonly used in fission reactions is uranium-235. This isotope undergoes nuclear fission when bombarded by neutrons, releasing energy in the process.
The atomic particles given off as a result of nuclear fission are?
The fission of uranium 235 gives on average 2.5 neutrons per fission. Now you may think it an odd figure, surely it must be a whole number? But in fact not all U235 nuclei follow the same route, a range of different fission products is formed, and when the yield of fission products is analysed, the graph of yield against atomic weight shows two peaks, one around AW 90 and one around 135, so a range of different elemental nuclei results. As well as the neutrons, there is a gamma ray release from the fission. The fission releases about 200 Mev, of which about 160 goes into the fission fragments, 30 into the gamma ray, and the rest into the neutrons. Therefore most of this energy release goes into the fission fragments which recoil and give up their kinetic energy as heat within the fuel elements. Many of the fission products go through subsequent decay with beta release, and once the reactor has operated for a few days and the population of fission products has settled down, these decays add appreciably to the heat generated, and when the reactor is shutdown for maintenance or refuelling this decay heat has to continue to be removed. Some of the fission products act as strong neutron poisons, so this is another factor that has to be allowed for in designing the fuel cycle. I should perhaps add that for the nuclear chain reaction to continue at a steady rate, one neutron from each fission has to enter another U235 nucleus, causing another fission, and so on. So the excess neutrons have to be controlled, or the power would go on rising. This can be done with control rods or soluble poisons, to augment the fission product poisoning mentioned. This is more important with new fuel loaded, as the fuel charge is used up the amount of poisoning needed reduces, and eventually if more new fuel is not loaded, the reactor will gradually shut itself down. There is a good Wikipedia article on 'Nuclear Fission', and if you look at this and follow some of the links you will find out more. One of the articles even has an animated diagram showing the fission process.
What is induced nuclear fission?
We might think of induced nuclear fission as a fission reaction that occurs when a neutron is captured by, say, a uranium-235 atom and that atomic nucleus undergoes fission as a result. Most all of the fission events within a nuclear reactor or nuclear weapon are induced. Given this, we might then compare that fission event to a spontaneous fission event wherein the atomic nucleus of a uranium-235 atom spontaneously undergoes fission without having captured a neutron.
Why is nuclear fusion less harmful than a nuclear fission?
Lack (or reduced) fission products. Fission products emit most of the harmful radiation in fallout.
How do the waste products of a fusion reaction differ from the products of a fission reaction?
Most (but not all) fusion products are non-radioactive. Virtually all fission products are strongly radioactive beta or gamma emitters.
Which three months are the most dangerous for tornadoes?
April, May, and June are generally the most dangerous months.
Is most of the energy released by nuclear fission is in the form of gamma rays?

Are some nuclear wastes stored for centuries to prevent dangerous radioactivity from escaping?
Yes. Some radioactive waste, like spent nuclear fuel, remains highly radioactive for thousands of years. Attempts were made to reprocess the spent fuel, but it is extremely dangerous and it is not very cost effective in many cases to do so. There are other forms of radioactive waste generated every day, but we work at being careful about what we generate to avoid having to store it. But the problem with nuclear fuel is a major one. Spent fuel is far and away the major contributor to high level radioactive waste in the world. Consider that 235U and 239Pu are the most common nuclear fuels. When they fission, they leave behind fission products. (The atom of fissile material "split in two" and there are a pair of fission fragments. Different pairs of fragments are possible.) With either fuel, there are over a dozen fission products from the fission process that have a half-life measured in thousands of years. There are a lot of fission products in the spent fuel, they are highly radioactive, and the remain highly radioactive for thousands of years after use. We can't just throw them away.
Is paint classed as dangerous goods?
Paint is a dangerous good and is classified under Flammable Liquids. If you read most of the content written in most paint products, they would have a warning regarding the hazards of the product.
