: Draw a horizontal line from this half-value to the curve, then a vertical line down to the time axis (x-axis). Nt=N0(12)tT1/2cap N sub t equals cap N sub

: 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: : : You cannot predict when a single

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 (

) of a radioactive isotope is the time required for half of the unstable nuclei in a sample to undergo radioactive decay. :

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