What Is This Tool?
This converter allows you to transform values of radioactive activity measured in curies (Ci) into disintegrations per second, the SI unit for activity. It enables clear communication and compliance with international standards by converting between a traditional and a modern unit.
How to Use This Tool?
-
Input the radioactive activity amount in curie (Ci).
-
Select curie as the source unit and disintegrations per second as the target unit.
-
Click convert to see the equivalent value in disintegrations per second.
-
Use the converted result to standardize activity reporting or for compliance purposes.
Key Features
-
Converts curie values to disintegrations per second (Becquerels).
-
Supports application in medical, industrial, and environmental radiation contexts.
-
Browser-based and easy to use for quick calculations.
-
Helps comply with regulatory and safety reporting standards.
-
Provides clear conversion with a fixed defined rate.
Examples
-
Convert 2 Ci: 2 × 3.7 × 10^10 = 7.4 × 10^10 disintegrations/second.
-
Convert 0.5 Ci: 0.5 × 3.7 × 10^10 = 1.85 × 10^10 disintegrations/second.
Common Use Cases
-
Expressing radioactive source strength in medical and radiopharmaceutical fields.
-
Reporting activity levels for regulatory inventory, labeling, and transport documentation.
-
Calibrating radiation detectors and measuring environmental radioactivity.
-
Standardizing measurements for industrial radiography and radiation gauging.
Tips & Best Practices
-
Use disintegrations per second for precise activity values aligned with SI units.
-
Apply curie values for large activity sources, common in medical and industrial contexts.
-
Follow safety and regulatory guidelines to choose the appropriate unit for your application.
-
Double-check conversions when handling very large numeric values for accuracy.
Limitations
-
The curie is a relatively large unit and not suitable for low radioactivity samples.
-
Handling large numbers is necessary when converting curies to disintegrations per second.
-
Regulatory requirements may restrict which unit is appropriate in certain contexts.

Key Terminology
-
Curie [Ci]
-
A non-SI unit of radioactive activity equal to 3.7 × 10^10 nuclear decays per second, historically defined based on radium-226.
-
Disintegrations per second
-
An SI unit of radioactive activity representing the number of nuclear decays per second, equivalent to one becquerel.
