The half life of a scandium-46 is 84 days. The scandium-46 is used in oil refining as a tracer to monitor the oil movement and it emits extremely high energetic gamma/beta radiation. So the half-life of the radioisotope scandium-46 is 84 days. The Scandium 46 created by neutron activation, is a synthetic isotope of Scandium.
