Q133 · CSIR-NET Chemistry, June 2011
Paper: CSIR-NET June 2011 · Subject: Physical Chemistry · Chapter: Nuclear Chemistry · Topic: Nuclear Chemistry – General · Marks: 2 · Difficulty: Easy
The penetrating power (R) and ionizing power (I) of $\alpha, \beta$, and $\gamma$ rays follow the ordering
(a)$\mathrm{R}_{\beta}>\mathrm{R} \gamma>\mathrm{R}_{\alpha}$ and $\mathrm{I}_{\beta}>\mathrm{I}_{\gamma}>\mathrm{I}_{\alpha}$
(b)$\mathrm{R}_{\gamma}>\mathrm{R}_{\beta}>\mathrm{R}_{\alpha}$ and $\mathrm{I}_{\beta}>\mathrm{I}_{\gamma}>\mathrm{I}_{\alpha}$
(c)$\mathrm{R}_{\beta}>\mathrm{R}_{\alpha}>\mathrm{R}_{\gamma}$ and $\mathrm{I}_{\alpha}>\mathrm{I}_{\beta}>\mathrm{I}_{\gamma}$
(d)$\mathrm{R}_{\gamma}>\mathrm{R}_{\beta}>\mathrm{R}_{\alpha}$ and $\mathrm{I}_{\alpha}>\mathrm{I}_{\beta}>\mathrm{I}_{\gamma}$
Answer
Answer: D ✓ checked by 4AB · confidence high
Explanation
Penetrating power runs γ > β > α, and ionising power the reverse, α > β > γ (d).
