Uses of Radioactive Isotopes. Their specific thickness is usually identified by measuring the strength of the radiation rays penetrating these metal or plastic sheets. These are some very important radioisotopes which are used in daily life. A sample of burnt wood discovered in an archaeological excavation is found to have a carbon-14 disintegration rate of 3.5 Bq. 14C has a relatively small half life of about 5730 years - so, nearly all of it should have depleted by now. Name two isotopes that have been used in radioactive dating. 1. If the atmosphere had a C14/C12 of 0.01%, then a C14/C12 of 0.005% means it died about 5,730 years ago. The half-life of radioactive isotopes is unaffected by any environmental factors, so the isotope acts like an internal clock. The radio-isotopes have wide applications in medicine, agriculture, industry and research. 2. Therefore, sometimes referred to. each carbon-14 atom loses an beta particle.
