Select the correct option

${}_{93}{}^{239} \mathrm{Np}$ is a $\mathrm{\beta }$-emitter, but the product is also radioactive and give ${}^{235}\mathrm{U}$. Which particle(s) is/are emitted by the product?

In the radioactive decay process

1. A and B are isobars

2. A and D are isotopes

3. C and D are isobars

4. A and C are isotopes

A radioactive sample is emitting $64$ times radiations than non-hazardous limit. If its half life is $2 \mathrm{h}$, after what time it become non hazardous?

If the quantity of a radioactive element is doubled, the rate of disintegration will

In nuclear transmutation ${}_8{\mathrm{O}}^{16}{\left(\mathrm{A},\mathrm{B}\right)}_7{\mathrm{N}}^{13}$ $\mathrm{A}$ and $\mathrm{B}$ are respectively
