What is a flight-time equivalent dose of radiation?

The flight-time equivalent dose is an informal educational unit used to measure ionizing radiation exposure by expressing it in units of flight time. One unit of flight-time corresponds roughly to the radiological dose received during the same duration spent inside an airliner at cruising altitude. It is designed to help people understand radiation doses by translating sieverts into familiar time units, though it is not a formally adopted measurement.

What we know

• Flight-time equivalent dose is an informal unit of measurement used for ionizing radiation exposure. [1, 2]
• Expressed in units like flight-seconds, flight-minutes, or flight-hours, one unit equals the dose received during that same time spent in an airliner at cruising altitude. [2]
• The metric is meant purely as an educational exercise to convert sieverts into time units for better understanding and is not formally adopted. [2]
