What does one per second (1/s) represent in radiation activity?

One per second (1/s) is the SI derived unit representing the occurrence of one nuclear decay or event per second, equivalent to one becquerel (Bq).

Why convert curie to one per second?

Converting to one per second standardizes measurements into SI units, which facilitates regulatory compliance, safety reporting, and consistent communication across various fields.

Is the curie still commonly used?

Curie remains in use for expressing radioactivity in some medical and industrial contexts but is often converted to SI units like becquerels or one per second for formal reporting.

What Is This Tool?

This converter transforms measurements of radioactive activity from curie (Ci), a traditional non-SI unit, into one per second (1/s), the SI derived unit representing the rate of nuclear decays or events per second.

How to Use This Tool?

Enter the numeric value in curie (Ci) you want to convert.
Select 'Curie [Ci]' as the source unit and 'One/second [1/s]' as the target unit.
Click the convert button to see the result expressed in one per second (1/s).

Key Features

Converts curie (Ci) values into one per second (1/s) accurately.
Supports applications in medicine, industry, and environmental monitoring.
Utilizes the standard scientific relationship where 1 Ci equals 3.7 × 10¹⁰ decays per second.
Browser-based and easy to use without installation.

Examples

2 Ci converts to 74,000,000,000 one per second (1/s).
0.5 Ci converts to 18,500,000,000 one per second (1/s).

Common Use Cases

Converting radioactive source activity for medical procedures and radiopharmaceutical dosing.
Specifying source strength in industrial radiography and radiation measurement devices.
Ensuring compliance with regulations for radioactive material inventory, labeling, and transport.
Environmental radiation monitoring and safety reporting.

Tips & Best Practices

Use scientific notation or appropriate prefixes (MBq, GBq) for large converted values.
Always verify unit selection before converting for accurate results.
Consider measurement uncertainties and calibration when interpreting results.

Limitations

Curie is a non-SI unit, so conversion to one per second is required for international standard compliance.
Large values can be cumbersome without scaling using SI prefixes.
Variations in source measurement and calibration affect the accuracy of conversions.
