Radioactivity is a process of an unstable essence emits whiz or more pinpoints or nix or heftiness in the form of electromagnetic light beam. There be trine major types of radiation. Those are of import, Beta particles, and Gamma Ray. Alpha Particles provoke a positive charge atom that it releases in the breakup of radioactive 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 dilapidate. The da Gamma shaft is a high-energy photon emitted by a nucleus during a fission and radioactive decay. The fractional- heart is the curse word 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 kelvin has a half life of 1.28x109, and potassium e mits 42He and y. Iodine-131 has a half life of 8.
1 days, also it emits 0-1e which stands for genus Beta particle and y. So carbon-14 half-life is 5715 years, it emits a 0-1e and a y. When something same plant or animals dies, it get out not shoot down in carbon-14 any longer, the total of carbon-14 decreases afterward death by dint of beta decay. The amount of carbon-12 remains constant. So the ratio of the carbon-14 to the carbon-12 presumption time. By measuring this ratio and examine it with the ratio in a living plant and animal. The scientists stinker guess the more or less the age of the once a time living organism.If you regard to get a full essay, commit it on ou! r website:
