1
Q
features of alpha particles
A
two neutrons,(helium nucleus)
low penetration power
stopped by paper
very ionising
2
Q
gamma ray feature
A
EM radiation
High penetration power
stopped by lead
weakly ionising
3
Q
beta particle feautures
A
electron released by nucleus
moderate penetration power
stopped by aluminium
moderately ionising
for each beta particles a neutron in the ulcers has turned to a proton
