) of a radioactive isotope is the time required for half of the unstable nuclei in a sample to undergo radioactive decay. :
: Activity is measured in Becquerels (Bq) , representing one decay per second. The Mathematical Formula The relationship between the decay constant ( ) and the half-life is defined by the following equation: Half-Life-Alyx-TRNT.rar
: Half-life is constant for a specific isotope and cannot be changed by physical or chemical means. ) of a radioactive isotope is the time
