Answer #1

1Mev has highest weighting factor as seen in graph

problem. 2

Gamma rays are the most penetrating of the radiations. Gamma rays are highly energetic waves and are poor at ionising other atoms or molecules. It cannot be said that a particular thickness of a material can absorb all gamma radiation. Many centimetres of lead or many meters of concrete are required to absorb high levels of gamma rays
