Question: 3 5 points the attenuation of a material can be...

Question details

3. (5 points) The attenuation of a material can be described by the half value layer (HVL). The HVL is the thickness of material needed to absorb half of the incident x-ray photons. In other words, if an x-ray beam of intensity lo hits a slab of material with a thickness equal to its HVL, the intensity of the x-ray beam on the other side of the slab will be 0.5*lo. If an x-ray beam with an intensity of lo hits a slab of material with a thickness equal to twice its HVL, will all of the x-ray photons be absorbed by the material? Why or why not?
