The Time It Takes For The Number Of Nuclei Of A Sample Of Radioactive Isotopes To Decrease By Half.
For example if there is a sample that has a count rate of 100 counts per minute (cpm) and it takes 30 seconds for it to reach a count rate of __50 cpm __then 30s is the half life for the sample. Some half life questions will be answered by reading a graph whilst other will be a calculation. 2 g → 1 g → 0.5 g → 0.25 g.
