RADIO ACTIVITY
Definition:The self- disintegrating, spontaneous activity in the form of emission of radiations by some unstable nuclei with atomic number greater than 83 is called natural Radio activity.Radio activity was discovered in 1896 by a French physicist "A.H. Becquerel".Radiations were classified into three types, according to their penetrating capacity they are. 1. α -- Particles. 2. β-- Particles. 3.γ-- Particles. A strong magnetic field is applied at right angles to the plane of the paper, the beam splits in to three distinct components.α-- Particles have least penetrating power. β-- Particles more penetrating power than α (Alpha) -- particles. γ-- Particles are most penetrating power than β(Beta) -- particles.Transmutation:Definition:The process of transformation of one element into another element by bombarding with high energy particles is known as "Transmutation".Definition:The process of change of one chemical element into another chemical element through natural radioactive day, such as αdecay and βdecay is known as "natural Transmutation".Examples of natural Transmutation are potassium - 40 to the Argon -- 40 which forms most of the Argon in air.

Good sources of energy:
• What is a good source of energy?
• Energy output per unit volume:
• The energy output per unit volume (or mass) of good source of energy should be high. The gas in LPG cylinder can be used by family of average size to cook food for about a month. To cook same amount of food using wood, we need a roomful of wood.
• Steady availability: The energy source should be available readily and for a long time.
• Safe and easy to use: The source of energy has to be safe and easy to use, A fuel that produces a lot of smoke is not a good source of energy, since it is not safe for people’s health. A nuclear power plant is not easy to build and operate.
• Easy to store and transport: Most common sources of energy such as coal, petrol, and LPG need to transport to users from their points of production.
• Economical: The source of energy has to be economical. Hydrogen is excellent fuel. But it is not widely used as it is costly to produce, store and transport it.
• What is a good fuel?
• How much heat does it release on burning?
• It should not produce a lot of smoke.
• The fuel should be available easily.
Matter is made up of atoms.
An atom is subdivided into protons, neutrons, and electrons.
The proton and neutron are found in the center of the atom and make up the nucleus.
The negatively charged particles called the electrons are found orbiting the atom.
The orbit of an electron is described as an electron cloud.

Live from the Nuclear Energy Assembly, NEI President and CEO Maria Korsnick presented the industry’s policy priorities and provided perspective on the future of nuclear energy. This is a once-in-a-generation moment defined by demand for carbon-free, reliable nuclear energy.
Climate change is one of the most pressing issues of our time — and schools have a sizable environmental impact. There are nearly 100,000 public K-12 schools in the United States occupying 2 million acres of land and producing 53,000 tons of food waste. Schools operate one of the largest mass transportation fleets in the country with 480,000 school buses, and they are one of the largest public energy consumers.
We’ll talk with national education leaders — members of an Aspen Institute bipartisan commission that recently released a K12 Climate Action Plan – about how the education sector can be a force toward climate solutions and environmental justice. Join us to talk about how schools and educators can help prepare young people to envision and work toward a more sustainable, resilient, and equitable society.
Speakers:
• John King, Jr., President and CEO, The Education Trust; former U.S. Secretary of Education
• Pedro Martinez, CEO, Chicago Public Schools
• Becky Pringle, President, National Education Association

energy released during a nuclear reaction as a result of fission or fusion Also called atomic energy. nuclear energy in Science Expand. nuclear energy. The energy released by the nucleus of an atom as the result of nuclear fission, nuclear fusion, or radioactive decay.
When an atom of nuclear fuel (uranium) absorbs a neutron, the uranium will fission into two smaller atoms (waste) and release one to three neutrons. The kinetic energy of the waste is used to heat the water for the steam turbine. The neutrons are used to fission the next lot of uranium atoms and the process continues.
This physics video explains the concept of nuclear fission reaction by illustrating an example of nuclear fission of Uranium 235 atom. Nuclear Fission produces Nuclear Energy! Nuclear Fission is a type of Nuclear Reaction where a heavy nucleus splits into lighter nuclei and releases an enormous amount of energy! We look at Einstein's Equation: E = mc2 and how it applies to Nuclear Reactions.

Chain Reaction in Nuclear Fission: When slow neutrons are bombarded on uranium, each uranium nucleus is broken in to two almost equal parts and along with it enormous energy and two or three trash neutrons are emitted. If the conditions are favorable, these neutrons take part in the fission.This leads to a chain of nuclear fissions which continues till the whole of the Uranium is consumed. Thus the energy produced keep on multiplying.We have seen that about 200 MeV MeV- mega electron volts of energy is released due to fission of 1 Uranium nucleus. In this chain reaction, the number of nuclei undergoing fission increases very rapidly, hence the energy produced acquires an enormous amount very soon."The chain reaction is a series of nuclear fissions in which the neutrons produced in each fission cause additional fissions."This chain reaction liberate tremendous amount of energy within short interval of time. But sustaining a self--propagating chain reaction is not easy in practice, because the progressive chain reaction is inhibited due to the following reasons.A Ordinary uranium consists of three isotopes 92U238 92 Uranium 238, 92U236 92 Uranium 236 and 92U235 92 Uranium 235. The major part of ordinary uranium is the isotope 92U238 92 Uranium 238 the remaining are rare. Now, 92U238 92 Uranium 238 can be fissioned only with fast neutrons 1 MeV while 92U235 can be fissioned with slow as well as slow and fast neutrons. Neutrons having energy less than 1 MeV are absorbed by 92U238 through these low energy neutrons can take part is the fission of 92U235 but the probability of their absorption by U238 is much more. Thus the fresh neutrons released in the fission of ordinary uranium being absorbed by U238 are not able continue the chain reaction. This difficulty can be removed in the following two ways: The lighter isotope U235 can be separated from the ordinary uranium by diffusion method. The fission of U235 is now possible by neutrons of any energy high or low. So chain reaction continuous as shows in above.The second way is to slow down the neutrons by any method. So that their energy remains 0.03 eV This can be achieved with help of moderators, which reduce the speed of neutrons very rapidly. Graphite and heavy water are good moderators.The second difficulty in maintaining the chain reaction is that the fast neutrons released by the fission of U235 travel a distance of about 10 centimeter in the substance before they are slow down and fission other nuclei.Therefore, to continue the chain--reaction, the size of the fissionable substance should be bigger than a certain critical size.
