Q
what is half life
A
is the time taken for the activity of a radioactive source to reduce by half
2
Q
how do you work out the half life from a graph
A
- pick a point
- draw across it
- draw down from it
- divide the activity by half
- repeat drawing lines
- the difference in time between the two points on the time axis in the half life
