Question 13The 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.source ASource Bsource C1 sheet 80 gsmpaper99.9%50%95%3mm thickaluminium plate90%0.1%1%5 mm thick leadplate50%0a) Identify the type of radiation being emitted from each source.b) The penetrating power of nuclear radiation is closely linked to its ability to ionize the material it is passingthrough. Explain why some types of radiation may be more strongly ionising than others. [Suggested word count150][5.1]

Different radioactive radiation have different ionising power and thus, different penetration depth.…
