Flight Radiation Calculator
Estimate the cosmic-radiation dose from a flight using trip duration, dose rate, and annual flight count.
The calculator is an estimate only, but it helps you compare short and long flights or frequent travel.

| Dose rate | -- |
| Total flight hours | -- |
Quick Answer
Multiply the flight duration by the dose rate to estimate radiation exposure for one trip, then multiply by annual trips if you want a yearly estimate.
How to Calculate
- Enter how long the flight lasts.
- Enter the dose rate per hour.
- Enter how many similar trips you take each year.
- Click Calculate.
Formula
Dose per flight = flight hours x dose rate
Annual dose = dose per flight x flights per year
Worked Examples
Example 1: A 6 hour flight at 0.003 mSv/hour gives 0.018 mSv.
Example 2: Ten such flights in a year gives 0.18 mSv.
Example 3: A longer flight with the same dose rate produces a larger total dose.
How to Interpret Your Results
| Output | Meaning | Action |
|---|---|---|
| Dose per flight | Estimated exposure from one trip. | Compare short and long routes. |
| Annual dose | Estimated yearly total if you fly repeatedly. | Use it to compare travel patterns. |
| Dose rate | The exposure assumption used in the calculation. | Change it if you have a better estimate. |
Frequently Asked Questions
No. It is a planning tool for approximate exposure, not a medical assessment.
Short flights usually add only a small amount of exposure, but your own situation may differ.
Yes. Replace the example number with a rate that better matches your flight profile.
