Write mathematical equations that show how you will calculate the detected activity from the count rate due to background radiation and the sample of KCl and how you will determine the “true” activity of your sample from the detected activity. Use the following symbols: (3.5 pts)

Question

R(background): count rate for background radiation

R(total): total count rate

R(detected): detected count rate from your sample

R(true): “true” count rate of your sample

Are these the correct equations?

R(total)=R(background)+R(detected)

R(true)= R(total)- R(background)

Answer 1

correct.
