Filters for Co K radiation are usually made of iron oxide power

  1. Nov 2, 2011 #1
    "filters for Co K radiation are usually made of iron oxide power. If a filter contains 5 mg Fe2O3, what is the transmission factor for the Co K(alpa) line? What is the intensity ratio of Co K(alpha) to Co K(beta) in the filtered beam?"

    I was wondering if you could expand further as I'm stuck. I found mass absorption for Fe2O3 alpha =44.61 cm2/g and beta = 245.7 cm2/g. but since i'm not given density of fe2o3 do i just presume (5.24g/cm3) it or can i do the maths and solve without it. your help is welcomed
