Bar chart of the dose equivalents received in the worse case during GLEs, calculated with the model SiGLE. Each group of four bars corresponds to a given GLE (number and date are indicated along horizontal axis). The first pair shows dose equivalents for Paris-New York flight on-board Concorde (GLE contribution in black, total dose in white). The second pair shows dose equivalents for Paris-San Francisco flight on-board Airbus A 340.
