A beam of protons is sent through a target and 60% get through. If the target then has its thickness doubled, what percent of the beam would then get through?

Question

The transmission of protons through a material typically follows an exponential decay model. If 60% get through initially, doubling the thickness would square the transmission probability, resulting in 0.6 * 0.6 = 0.36 or 36%.
