Enter the attenuation coefficient and the mass density into the Calculator. The calculator will evaluate the Mass Absorption Coefficient. 

Mass Absorption Coefficient Formula

MSC = u / p


  • MSC is the Mass Absorption Coefficient ()
  • u is the attenuation coefficient
  • p is the mass density

To calculate Mass Absorption Coefficient, divide the attenuation coefficient by the mass density.

How to Calculate Mass Absorption Coefficient?

The following steps outline how to calculate the Mass Absorption Coefficient.

  1. First, determine the attenuation coefficient. 
  2. Next, determine the mass density. 
  3. Next, gather the formula from above = MSC = u / p.
  4. Finally, calculate the Mass Absorption Coefficient.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

attenuation coefficient = 40

mass density = 20
