What does 1 curie represent in radioactive activity?

1 curie corresponds to the activity of one gram of radium-226 and equals 3.7 × 10^10 nuclear decays per second.

Why is the rutherford unit considered obsolete?

The rutherford has been replaced by the SI unit becquerel and is mainly encountered in historical scientific and radiochemistry contexts.

When should I convert curie to rutherford?

Conversions are useful for interpreting older experimental data, educational comparisons, and historical records where rutherford was used.

Enables comparisons between outdated and current radiation activity units.

Examples

2 Ci converts to 74000 Rutherford.
0.5 Ci converts to 18500 Rutherford.

Common Use Cases

Translating radioactive activity measurements from modern to historical units found in older literature.
Analyzing early nuclear experiment data or historical radiochemistry records.
Educational purposes for understanding differences between obsolete and SI units.
Regulatory or safety evaluations referencing archival radiation activity data.

Tips & Best Practices

Use this conversion mainly for historical or educational contexts due to the rutherford's obsolescence.
Verify units carefully when interpreting older radiation data to avoid confusion.
Refer to SI units such as becquerel for official regulatory and safety documentation.
Understand the scale difference: 1 Ci equals 37000 Rutherfords to ensure correct conversions.

Limitations

The rutherford unit is no longer used in contemporary radiation practice, limiting its applicability.
Conversion precision may vary for very large or very small values due to rounding factors.
Official reports generally require SI units like the becquerel for compliance and clarity.
