: Draw a horizontal line from this half-value to the curve, then a vertical line down to the time axis (x-axis).

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

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 ( : Draw a horizontal line from this half-value

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

: You cannot predict when a single nucleus will decay, but you can predict the behavior of a large sample.

: 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:
