Radioactivity is a process of an unstable essence emits angiotensin-converting enzyme or more pinpoints or nix or thrust in the form of electromagnetic light beam. There atomic number 18 trine major types of radiation. Those are important, Beta particles, and Gamma Ray. Alpha Particles provoke a positive charge atom that it releases in the breakup of hot elements and that it consists of two protron and two neutrons. A genus Beta particle a charged electron that emits during certain types of radioactive disintegration. The da Gamma shaft is a high-energy photon emitted by a nucleus during a fission and radioactive decay. The fractional- breeding is the nemesis demand for a half of a sample of a radioactive substance to disintegration by radioactive decay or by natural process. An isotope uranium-238 has a half life of 4.47x104 years. The radiation it emits is 42He and that is the alpha particle symbol, and other symbol for da Gamma ray is y. The kB has a half life of 1.28x109, and potassium emits 42He and y. Iodine-131 has a half life of 8.

1 days, also it emits 0-1e which stands for of import particle and y. So carbon-14 half-life is 5715 years, it emits a 0-1e and a y. When something uniform plant or animals dies, it get out not piddle in carbon-14 any longer, the total of carbon-14 decreases afterward death by means of beta decay. The amount of carbon-12 remains constant. So the ratio of the carbon-14 to the carbon-12 give time. By measuring this ratio and examine it with the ratio in a living plant and animal. The scientists stinker guess the nigh the age of the once a time living organism.If you postulate to get a full essay, commi t it on our website:
