Frequently Asked Questions
How many Becquerels are in 1 Curie?
Exactly 37,000,000,000 Becquerels (37 GBq or 3.7 × 10¹⁰ disintegrations per second). By international convention, 1 Curie is legally defined as exactly 37 billion disintegrations per second.
Why is the Becquerel preferred in modern science?
The Becquerel is the official SI unit of radioactivity. Unlike the historical Curie (which was based on 1 gram of Radium-226 and varied with measurement precision), the Becquerel has a direct, exact relationship with SI base units (1 Bq = 1 s⁻¹).
What is the difference between radiation activity and radiation dose?
Activity (measured in Bq or Ci) measures the number of nuclear disintegrations occurring per second from a radioactive source. Dose (measured in Grays or Sieverts) measures the physical energy deposited into matter or human tissue and the corresponding biological harm.
