Switch between activity, dose, and exposure units easily. Review results, trends, and reference values quickly. Export clean reports for study, lab, safety, or training.
Convert radiation values inside the correct measurement category. This calculator handles activity, absorbed dose, equivalent dose, and exposure units separately.
Important: activity, dose, equivalent dose, and exposure are different physical quantities. This tool converts units within the selected category only.
Use the responsive input grid below. Large screens show three columns, medium screens show two, and mobile screens show one.
This converter uses a base unit for each radiation category. First, it converts the entered value into the category base unit. Then it converts that base value into every other unit in the same category.
Base Value = Entered Value × Factor of Selected Input Unit
Target Unit Value = Base Value ÷ Factor of Target Unit
| Category | Sample Input | Equivalent Example | Why It Matters |
|---|---|---|---|
| Activity | 2 mCi | 74,000,000 Bq | Useful for source strength comparisons. |
| Absorbed Dose | 0.25 Gy | 25 rad | Shows deposited energy in matter. |
| Equivalent Dose | 5 mSv | 500 mrem | Common in safety monitoring reports. |
| Exposure | 10 R | 0.00258 C/kg | Useful for air ionization reference values. |
No. It converts only within the selected category. Activity, absorbed dose, equivalent dose, and exposure describe different physical quantities, so they should not be mixed automatically.
Gray measures absorbed energy per kilogram. Sievert represents biological effect after applying weighting concepts. They may look similar numerically in some cases, but they are not interchangeable without context.
Radiation units often differ by many orders of magnitude. A single value in curies or gigabecquerels can look huge compared with becquerels, so the bar chart may span a wide numerical range.
Use scientific notation when values are extremely large or extremely small. It keeps results readable, especially for becquerel-based activity data and micro-level exposure or dose values.
No. The calculator converts the unit scale only. It uses the identity 1 Sv = 100 rem. It does not calculate weighting factors for radiation type or tissue sensitivity.
Roentgen measures exposure in air, not absorbed dose inside tissue. It is useful for ionization comparisons in air and older radiation references, but modern reports often prefer SI units.
Disintegrations per minute is another way to express radioactive decay rate. Because activity counts transformations over time, dpm fits within the activity category and converts through becquerels.
Yes. The export buttons make it useful for classroom work, lab notes, internal training, and quick comparison reports. Always verify official safety documents with your governing standards.
