Flight Radiation Calculator

Estimate radiation exposure on a flight.

Dose (µSv) 24

Equivalent chest X-rays 1.2

Step-by-step with your numbers:

1. Values used:

2. Flight time = 8

3. Dose = 24µSv

4. Equivalent chest X-rays = 1.2

Did we solve your problem today?

High-altitude flying increases cosmic radiation exposure.

The math behind it

Dose ≈ 3 µSv per flight hour at cruising altitude. ~20 µSv per chest X-ray.

Dangerous?

Even frequent flyers receive doses well below recommended limits.
