Question 66

In a paper mill, a beta radiation source and detector are used to monitor the thickness of the paper produced. The nominal (ideal) detected count rate is $second350\text{ counts per second}$ .

The rollers must be adjusted if the count rate increases by 6%.

Calculate the maximum count rate that is allowed before the rollers need to be adjusted.
