In the modern days, we use nuclear power as a source of energy for everyday living. Using nuclear energy causes some benefits and also problems. Nuclear power stations do not usually cause air pollution, and it also reduces greenhouse gas emissions. We often use it for the conservation of fossil fuels. However, there are problems that is need to be concerned about using nuclear energy where it produces a large amount of radiations and it is difficult for disposal.
We use nuclear energy for medicine and industry. Nuclear energy produces electricity for the running of industrial machines. It does not only conserve valuable fossil fuels, which cause greenhouse effect. It also reduces greenhouse gas emissions and reduces the problem of acid rain.
Although nuclear energy is greenhouse friendly, it does cause a lot of problems. Radioactivity is one the most important issue that has brought by using nuclear energy.
In the atomic model, when an element's neutron is more than its proton, it is called an unstable isotope. Unstable isotopes lose or gain neutrons and protons to gain stability, the loss of particles and energy is radioactivity.
Radioactive decay occurs when an unstable isotope breaks down into another same or different element. This decay process continues until stable isotope forms-where neurons and protons are approximately the same. There are 3 types of radiation, Alpha, beta and gamma. The time it takes an unstable isotope to halve its mass and to decay into a stable isotope is the half-life. Too much radiation could be dangerous where people can only be exposed to a fairly small amount of radiation per year without increasing their risk of developing cancer. And when large isotopes eg Uranium split, it releases all its binding energy very quickly, therefore atomic bombs will form.
