nuclear physics Flashcards
1
Q
penetrating power of alpha, beta and gamma radiation
A
alpha - not penetrating
beta - stopped in a few meters of air
gamma - stopped by 3cm of lead
2
Q
nuclear fission
A
the splitting of the nuclei into two smaller nuclei
3
Q
beta decay
A
neutrons turns into a proton and and electron is emitted
4
Q
under what conditions can nuclear fusion occur
A
takes place only at high tempteratures to get over the coulomb repulsion
5
Q
radioactivity
A
radio active nuclides decay spontaneously via alpha, beta and gamma decay
