: The distance from zero to that point on the time axis is one half-life. Examples of Isotopes

: You cannot predict when a single nucleus will decay, but you can predict the behavior of a large sample. Half-Life-Alyx-TRNT.rar

: 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: : The distance from zero to that point

A common method for finding half-life is using a decay curve (activity vs. time). : Locate the starting point ( N0cap N sub 0 ) on the vertical axis (y-axis). Calculate Half-Value : Divide the initial activity by 2 ( The Mathematical Formula The relationship between the decay

Nt=N0(12)tT1/2cap N sub t equals cap N sub 0 open paren one-half close paren raised to the the fraction with numerator t and denominator cap T sub 1 / 2 end-sub end-fraction power Determining Half-Life from a Graph

: Half-life is constant for a specific isotope and cannot be changed by physical or chemical means.
