Line 111:

where μ is the [[linear attenuation coefficient]], μ/ρ is the [[mass attenuation coefficient]] and ρ is the [[density]] of the material. The [[Mass attenuation coefficient]] can be looked up or calculated for any material and energy combination using the [[National Institute of Standards and Technology|NIST]] databases
