Q13.25Multiple choice
The activity R of an unknown radioactive nuclide is measured at hourly intervals. The results found are tabulated as follows: t (h) 0 1 2 3 4 R (MBq) 100 35.36 12.51 4.42 1.56
- (i)Plot the graph of R versus t and calculate half-life from the graph. R
- (ii)Plot the graph of ln versus t and obtain the value of R0 half-life from the graph.
