Question

Ionization power and penetration range of radioactive radiation increases in the order

• A. \( \gamma, \beta, \alpha \) and \( \gamma, \beta, \alpha \) respectively
• B. \( \gamma, \beta, \alpha \) and \( \alpha, \beta, \gamma \) respectively
• C. \( \alpha, \beta, \gamma \) and \( \beta, \gamma, \alpha \) respectively
• D. \( \alpha, \beta, \gamma \) and \( \beta, \gamma, \alpha \) respectively

Hint:

Gamma rays have high penetration power, while alpha particles have high ionization power.

Answer 1

The Correct Option is B

Step 1: Understanding the properties of radiation.
Gamma rays have the highest penetration range and lowest ionization power, while alpha particles have the highest ionization power but the lowest penetration range.

Step 2: Conclusion.
Therefore, the correct order is \( \gamma, \beta, \alpha \) for penetration and \( \alpha, \beta, \gamma \) for ionization. Hence, the correct answer is option (B).

Final Answer: \[ \boxed{\text{(B) } \gamma, \beta, \alpha \text{ and } \alpha, \beta, \gamma \text{ respectively}} \]
