Cosmic radiation on flights from Singapore (SIN)

Singapore Changi Airport, Singapore, Singapore. ICAO WSSS, at 1.36°, 103.99°. FlightDose publishes 3 routes from here and 3 to here, each direction on its own page.

Of the 3 published routes from SIN, the flight to Sydney (SIN → SYD) receives the least, about 14.9 µSv for a standard flight, and the flight to San Francisco (SIN → SFO) the most, about 39.1 µSv. A route's dose depends mostly on its hours in the air and how far it runs from the equator (why latitude matters).
