B please, help 

The following table shows the percentage of the intensity of radiation that passes through sheets of paper, aluminium and lead from three radioactive sources, each emitting only one kind of radiation. 1 sheet 80 gsm paper 3mm thick aluminium plate 5 mm thick lead plate 8 source A 99.9% 90% 50% source B 50% 0.1% 0 source C 95% 1% a) Identify the type of radiation being emitted from each source. A= gamma B=alpha C= beta b) The penetrating power of nuclear radiation is closely linked to its ability to ionize the material it is passing through. Explain why some types of radiation may be more strongly ionising than others. ARCANE MAHON 0
