Physics

Consider photons of ionising energy incident on a small volumeof a medium and which interact in the medium. By referring to theresulting interactions and product particles, explain thedifference between the terma, kerma, collision kerma, rad iativekerma, and the absorbed dose in the medium. Relate each to theincident particle fluence.
