Question

A radioactive isotope has a half life for 14 days. It had an initial count rate of 36000 Bg. What will the count rate be after 1 hour?

Answer 1

107.14 Bg

Step-by-step explanation:

24 hours = 1 day

1 hour = 1/24 day

14 days = 36000 Bg

1/24 day = y

14y = 1/24 × 36000

14y = 1500

y = 1500/14 = 107.14 Bg
