The density thickness of absorber 11 is 7435 mg/ cm^2

Question 4 a. What is your computed value for the mass attenuation coefficient of lead? b. How does this compare to the accepted value of 5.9 10-5 cm/mg? Your error may be 5%. d. What density thickness would you need to reduce the intensity of radiation by 1/2? Use the accepted value of the mass attenuation coefficient in your calculation. e. How much lead is this? Estimate the number of the thickest lead absorbers (absorber 11) you would need to add up in order to achieve the requirement calculated in part d.
