11.) Calculate both the gamma and beta absolute detection efficiencies and compare them. Describe the reason for the differences. Note: You will need to use the respective emission probabilities to determine the denominator in the equation. 12.) Using NIST data and measured thickness of the Al sheet from part 2, explain why the GM measurement with the Al sheet was only measuring photon counts
