To determine the mass of carbon-14 that needs to be present in a sample to have an activity of 1.00mCi. Concept introduction: Carbon-14 is a radio-active isotope of carbon. It consists of 8 neutrons and 6 protons. Its half-life is said to be 5700 years. Carbon-14 is an emitter of beta particles. It is formed naturally and is generated by the interaction of neutrons with the nitrogen-14 present in the earth’s atmosphere. These neutrons are formed by the cosmic rays upon interaction with the atmosphere.
