Name some radionuclides used in radiodiagnostics.

A single radionuclide upon which over 80% of diagnostic procedures in modern nuclear medicine rely on is _____.

Why alpha particles are used for treating leukaemia?

State Bragg's peak effect.

What are the uses of magnetic resonance imaging?

Radioisotope used for the treatment of blood disorder and skin disease is

Which of the following method is not using ionising radiations?

In the chain reaction.

${}_{92}{}^{238}\mathrm{U}⟶\mathrm{Ba}+\mathrm{Kr}+3{}_0{}^1\mathrm{n}+$ energy $\mathrm{E}$

neutrons and energy produced at $\mathrm{n}$ th step will be

Cotyledons are also called-

${ }^{227}\mathrm{A}\mathrm{c}$ has a half-life of 22 years with respect to radioactive decay. The decay follows two parallel paths: ${ }^{227}\mathrm{Ac}\to \mathrm{ }{ }^{227}\mathrm{T}\mathrm{h}$ and ${ }^{227}\mathrm{Ac}\to { }^{223}\mathrm{F}\mathrm{r}$ . If the percentage of the two daughter nuclides are $2.0$ and $98.0$ , respectively the decay constant (in $\mathrm{y}\mathrm{e}\mathrm{a}{\mathrm{r}}^{-1}$ ) for ${ }^{227}\mathrm{Ac}\to \mathrm{ }{ }^{227}\mathrm{T}\mathrm{h}$ path is closest to

At radioactive equilibrium, the ratio between number of atoms of radioactive elements A and B is $3.1\times {10}^9 :1$. If the half-life period of A is $2\times {10}^{10} yrs,$ then the half-life of B is

The number of neutrons accompanying the formation of ${}_{\text{54}}^{\text{139}}\text{Xe}$ and ${}_{\text{38}}^{\text{94}}\text{Sr}$ from the adsorption of a slow neutron by ${}_{\text{92}}^{\text{235}}\text{U}$ followed by nuclear reaction is.
