ok part b) Take reading without paper in between .. Take reading with paper in between .. subtract the two to give an estimate amount of alpha particles being released .. u might no the reason to choose paper .. its a good absorber for alpha ..
c) 1. use tongs/forceps to handle the radioactive material to keep some distance ..
2. use protective clothing gloves/coat etc.
