How to use the radiation dose calculator
Convert absorbed dose to equivalent dose in sieverts. Enter absorbed dose, radiation weighting in the fields above; the equivalent dose are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “gray to sievert”, “radiation exposure risk”, “weighting factor”, “calculate radiation dose”, “find equivalent dose”.
Formula
Variables
- D — Absorbed dose (mGy)
- wr — Radiation weighting
Worked example
With absorbed dose = 2 mGy, radiation weighting = X-rays and gamma, the calculator gives equivalent dose ≈ 2 mSv; equivalent dose ≈ 200 mrem.
Frequently asked questions
What is the radiation dose calculator used for?
Convert absorbed dose to equivalent dose in sieverts. It helps with questions such as “gray to sievert”, “radiation exposure risk”, “weighting factor”.
What is the formula for the radiation dose calculation?
Equivalent dose (mSv) = D × wr. Equivalent dose (mrem) = [Equivalent dose] × 100. Here D is absorbed dose (mGy), wr is radiation weighting.
What inputs do I need for the radiation dose calculator?
You need absorbed dose in mGy, radiation weighting. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the radiation dose calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the radiation dose result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
