Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

i have a critical question.

You have a point source (radioactive)..that emits 100 gamma per second. Now if you place a metal or foil (e.g., Al)..will the no. of gamma reduces??? If it reduces how to calculate..based on beer law..(if we know the attenuation coefficient of that metal and the energy of that 100 gamma)..sometimes i get confused with intensity and number of gamma quanta.

thanks for your reply
