FREE Radioactivity and the Nuclei of Atoms Essay.
There are many forms of radiation 3. Some forms of radiation are found in the natural environment and others are due to modern technology 2 3.Whether natural or man-made, radiation can be both harmful and beneficial to the environment 2 3.The sun, for example can have positive and negative effects on plant and animal life.
Radioactivity. Radioactivity refers to the particles which are emitted from nuclei as a result of nuclear instability. Because the nucleus experiences the intense conflict between the two strongest forces in nature, it should not be surprising that there are many nuclear isotopes which are unstable and emit some kind of radiation.
Radiation effects on DNA, wherein radiation exposure results in mutation of cells, is one of the most prominent effects of ionization radiation in the long run. The mutations in this case, can be teratogenic (which affects only the individual who was exposed) or genetic (the effects of which are passed on to the next generation).

Michael F. L'Annunziata, in Handbook of Radioactivity Analysis (Third Edition), 2012. I Introduction. Radioactivity is the emission of radiation originating from a nuclear reaction or as a result of the spontaneous decay of unstable atomic nuclei. The term radioactive decay refers to the process whereby unstable atomic nuclei decay with the loss of energy by the emission of elementary.
Nuclear energy is an alternative energy but not a renewable energy as Uranium is a non-renewable source and its supplies are limited. Terrorism Nuclear plants may be vunerable targets to anyone wanting to disrupt the power supply, and to have quite horrific results and to devastate an entire region.
Radioactive pollution is the presence of radioactive substances in the environment. These substances are known as pollutants because they can cause damage to the environment. Animals, plants and humans can all fall ill due to radioactive pollution.
