A radio"raph is a shadow picture produced by the passa"e of L(rays or "amma G rays throu"h an obect onto a film. 7hen the rays pass throu"h the obect, part of the radiation penetrates the material and part is absorbed. 2he amount of radiation absorbed and the amount that penetrates are a function of the thic*ness of the material. 7here a !oid
