Problem 42819. attenuation

A beam of X-rays propagates a length d(1) through a medium with an attenuation coefficient alpha(1). After that the beam propagates a length d(2) through a medium with an attenuation coefficient alpha(2) and so on... Calculate the percentage of transmitted intensity compared to the initial intensity!

Hints: 1.) Lambert-Beer law, 2.) [d]=1m, [alpha]=1/m
