rrect Question 4 This time the intensities of the X-ray beams are measured after each beam has travelled a different distance in each medium. Rank the intensities measured in the following scenairos from the highest intensity (1st) to the lowest (5th). Use the total linear attenuation coefficients from the previous question. 1st (Highest Intensity) 0.5 mm of lead 2nd 5 cm of calcium 3rd 8 cm of aluminium 4th 11 cm of water 5th (Lowest Intensity) 120 m of air

Question

please question 4.

Que
Five 50 keV X-ray beams of the same initial inensity are directed
through five different media: aluminium, air, calcium, lead and water.
The intensity of the X-ray beams is measured after they have travelled
through 10 cm of each material. Rank the intensities of the X-ray beams
from highest (1st) to lowest (5th) after they pass through the medium.
The total linear attenuation coefficients for a 50 keV beam in these
materials are:
Aluminium - 1.0 cm
Air -0.0002 cm-1
Calcium 1.5 cm-1
Lead - 90.0 cm-1
Water -0.2 cm-1
