Does the amount of radiation (cpm) increase or decrease as the distance between the source and the sensor increases ? Explain.Does the amount of radiation (cpm) increase or decrease as the thickness of the shielding increases (while the distance between the source and the sensor stays the same)? Explain.Does the amount of radiation (cpm) change when shielding made from different materials is used ? Explain.Based on your answers to 1 to 3, what are three factors that can allow us to reduce the amount of radiation exposure ? Explain.Based on your data, which is better for use as a radiation shield, Al or Pb? Why might the other one be used in certain applications?
