Hot Flights Table

Every day we monitor approximately 1400 flights criss-crossing the 10 busiest routes in the continental USA. Typically, this includes more than 80,000 passengers per day. Using E-RAD, we calculate the radiation exposure coming from cosmic rays for every single flight. The Hot Flights Table is a daily summary of the results.  


Our Hot Flights Table shows: 

  • the 5 charter flights with the highest dose rates

  • the 5 commercial flights with the highest dose rates

  • the 5 commercial flights with near-average dose rates

  • the 5 commercial flights with the lowest dose rates.

Passengers typically experience dose rates that are 20 to 70 times higher than natural radiation at sea level.

*Note: Table displays best on computer screens.




  • FLIGHT: Airline and flight number

  • DOSE RATEThe maximum dose rate during the flight, expressed in units of natural radiation at sea level

  • TOTAL DOSE: As expressed in dental X-rays. This is for a typical panoramic dental x-ray as indicated by the American Dental Association

  • ALTITUDEThe maximum altitude of the plane in feet above sea level

  • ORIGINDeparture city

  • DESTINATION: Arrival city

  • DURATION: Duration of the flight.

Our research is 100% crowdfunded through fundraising for our spaceweather ballooning program, Earth to Sky Calculus.
