How to Use Radiation Converter
The Radiation Converter translates between the SI and legacy units used in radiological protection.
- Pick a category — Absorbed dose, equivalent dose, activity, or exposure.
- Enter a value and the source unit.
- Pick the target unit — Within the chosen category.
- Read the result — The Radiation Converter returns the converted value with full precision.
Formula & Theory — Radiation Converter
The Radiation Converter applies fixed conversion ratios within each category:
1 Gy = 100 rad (absorbed dose)
1 Sv = 100 rem (equivalent / effective dose)
1 Ci = 3.7×10¹⁰ Bq (activity)
1 R = 2.58×10⁻⁴ C/kg (exposure)| Quantity | SI unit | Legacy unit |
|---|---|---|
| Absorbed dose | gray (Gy) | rad |
| Equivalent dose | sievert (Sv) | rem |
| Activity | becquerel (Bq) | curie (Ci) |
| Exposure | C/kg | roentgen (R) |
Assumptions and Limits
The Radiation Converter does not convert between different physical quantities — for example, you cannot convert activity to dose without knowing source geometry, energy, and absorption properties. Always stay within one category.
Use Cases for Radiation Converter
- Medical imaging — Translate legacy mGy and mSv values across reports.
- Radiation safety — Convert worker dose limits between rem and Sv.
- Nuclear medicine — Move between Ci and Bq for activity orders.
- Education — Visualize how SI and legacy units relate.
The Radiation Converter removes the friction of mixed-unit dosimetry documentation.
