Which do you think will penetrate farther into a block of lean, x-rays or gamma rays? Explain your reasonings.

i dont know if you mean lead instead of lean .anyway i think gamma rays will penetrate further this is because gamma rays are very penetrating , they have a shorter wave lenght than X-rays because the energy which produced them is greater . Although both are similar but X-rays will become weaker and less penetrating when passing through a block of lead unlike the gamma rays eventhough it might reduse their intensity  > but both will never stop ! . This is a hard question!!  'cause both are similar but as i said i think gamma rays will penetrate further
