Radioactive iodine is used to diagnose the disease of

Artificial transmutation was discovered by

In the nuclear reaction $_4^9Be(p, \alpha)X$,the $X$ is

The isotope $_{92}U^{235}$ decays in a number of steps to an isotope of lead $_{82}Pb^{207}$. The groups of particles emitted in this process will be

An artificial radioactive isotope gave $_7^{14}N$ after two successive $\beta$-particle emissions. The number of neutrons in the parent nucleus must be
