Examples of radioactive decay Alpha decay: A nucleus emits an alpha particle (a helium nucleus) and transforms into another element. Example: 84210 Po →82206 Pb+24 He Beta minus decay: A nucleus emits an electron and an antineutrino and transforms into another element. Example: 614 C →714 N+e−+ν Beta plus decay: A nucleus emits a positron and a neutrino and transforms into another element. Example: 611 C →511 B+e++ν Gamma decay: A nucleus emits a gamma ray (a high-energy photon) and remains the same element. Example: 2860 Ni →2860 Ni+γ Neutron emission: A nucleus emits a neutron and transforms into another element. Example: 86218 Rn →86217 Rn+n Carbon-14 dating: A method of estimating the age of organic materials based on the decay rate of carbon-14. Example: A sample of wood has a carbon-14 activity of 10 counts per minute. The half-life of carbon-14 is 5730 years. How old is the wood? Alpha: _ {84}^ {210}\text {Po}\rightarrow _ {82}^ {206}\text {Pb} + _ {2}^ {4}\text {He} 84210 Po →82206 Pb+24 He ... Calculations Using the First Order Rate Equation:
