Question

Tritium, a radioactive isotope of hydrogen, emits which of the following particles?

• A. Gamma $\left(\gamma \right)$
• B. Beta $\left(\beta \right)$
• C. Alpha $\left(\alpha \right)$
• D. Neutron (n)

Answer 1

The correct option is B Beta $\left(\beta \right)$

Tritium is radioactive and emits low energy $\beta$ particles
$t_{\frac{1}{2}}=12.33years$
${}_1^{3}H⟶{}_2^{3}He+{}_{-1}^0\beta$
