4. An X-ray beam of intensity 200 Wm-2 was administered to a patient. The beam moved a distance 20 mm through flesh which has an attenuation coefficient of 0.5 cm¯¹. The beam then moved 25 mm through bone which has an attenuation coefficient of 4 cm-¹. a. Calculate the intensity of the emerged beam of X-ray. b. Compare the intensity of the emerged beam to the original intensity.
