7 a Explain what is meant by the contrast in a radiograph and indicate how it can be optimised. b The half-value thickness of 30 keV X-rays in aluminium is 2.4 mm. A homogeneous 30 keV beam, of intensity 0.4 MW m-² passes through an aluminium filter. Find the linear attenuation coefficient of aluminium for this beam i ii the thickness of filter required to reduce the beam intensity to 60 kW m-² iii the emerging beam intensity if the filter is 4 mm thick.
