Write a mathematical equations that show how you will calculate the detected activity from the count rate due to background radiation and the sample of KCl. also, write an equation that shows how you will determine the "true" activity of your sample. Use the following terms:

R(background) = count rate for background radiation
R(total) = total count rate detected from your sample and background
R(detected) = detected count rate from your sample less the background radiation
R(true) = the "true" count rate of your sample.
