What Is This Tool?
This converter transforms measurements of radioactive activity from gigabecquerels (GBq), an SI-derived unit, to curies (Ci), a traditional non-SI unit. It is designed to support users in fields like nuclear medicine, radiopharmaceutical manufacturing, and radiation safety by enabling seamless conversion between these units.
How to Use This Tool?
-
Enter the radiation activity value measured in gigabecquerels (GBq)
-
Select the target unit as curie (Ci)
-
Click the convert button to obtain the equivalent value in curies
-
Use the result for reporting, regulatory documentation, or radiation safety purposes

Tips & Best Practices
-
Verify unit consistency when preparing regulatory or clinical documentation
-
Use this converter to facilitate communication between regions using different activity units
-
Consider the non-SI status of curie when applying conversions in international contexts
-
Confirm values carefully to avoid confusion due to rounding or unit differences
Limitations
-
Curie is less commonly used worldwide compared to the SI units becquerel and gigabecquerel
-
Conversion precision may be affected by rounding in practice
-
Differences in unit definitions over time can introduce slight inconsistencies
-
Careful attention is needed to maintain clarity in regulatory and clinical environments
Frequently Asked Questions
-
What does one gigabecquerel represent?
-
One gigabecquerel (GBq) equals 10^9 becquerels, where one becquerel corresponds to one nuclear decay per second.
-
Why convert gigabecquerel to curie?
-
Conversion to curie allows expressing radioactive activity in a traditional non-SI unit commonly used in medical, industrial, and regulatory settings.
-
Is the curie unit still widely used?
-
While curie remains relevant in some applications, it is less commonly used globally than becquerel or gigabecquerel.
Key Terminology
-
Gigabecquerel (GBq)
-
A derived SI unit of radioactive activity equal to 10^9 becquerels; measures nuclear decays per second.
-
Curie (Ci)
-
A non-SI unit representing radioactive decay rate, originally defined as the activity of one gram of radium-226.
