The radioactive nucleus $_7N^{13}$ decays to $_6C^{13}$ through the emission of

When $_{90}^{228}Th$ transforms to $_{83}^{212}Bi$,the number of emitted $\alpha$- and $\beta$- particles is,respectively:

How are gamma rays produced?

In an $\alpha$-decay,the kinetic energy of the $\alpha$-particle is $48 \, MeV$ and the $Q$-value of the reaction is $50 \, MeV$. The mass number of the mother nucleus is: (Assume that the daughter nucleus is in the ground state)

Neutrino is a particle which $\qquad$

The unit for nuclear dose given to a patient is
