    Could you please explain why thickness of TVL1 is more than TVLe which is opposite to the HVL1 and HVL2 concepts... Thickness of first HVL is less than thickness of 2nd HVL because 1st HVL interact with less harden beam than 2nd..

    Are we not missing the distance in the barrier transmission factor equation?
