What is the value of one curie (Ci) in SI units of radioactivity?

Correct option is D

The correct answer is (d) 3.7 × 10¹⁰ disintegrations per second
Explanation:
• The curie (Ci) is a non-SI unit of radioactivity.
• 1 curie = 3.7 × 10¹⁰ disintegrations per second (dps).
• It is based on the decay rate of 1 gram of radium-226.
• The SI unit of radioactivity is the becquerel (Bq).
• 1 Ci = 3.7 × 10¹⁰ Bq.
Information Booster:
• 1 Bq = 1 disintegration per second.
• Curie is still used in medical and nuclear industries.
Additional Knowledge:
(a) 3.7 × 10⁶ → Too low.
(b) 1.6 × 10¹⁰ → Not standard.
(c) 6.02 × 10⁸ → Not related to radioactivity.
