Seemingly simple radiation error

  1. Jan 24, 2008 #1
    1. The problem statement, all variables and given/known data

    'Cobalt 60 decays to nickel 60 by beta decay and gamma ray emission. The radiation from this decay is used to irradiate some food to extend its shelf life. If the count rate of decay events is 32 counts per second , and events are counted for 8 seconds what is the uncertainty in the count over the total counting period? What is the fractional uncertainty?’

    2. Relevant equations

    3. The attempt at a solution

    How do i know what the error is?!? maybe im being really dense here but i dont feel like there is enough info like 32 countsper sec +/- 1?
