Vague memory that they did some testing about the time the Concorde entered service that basically said it was no worse than other long haul aircraft.
Went something like this - the dose per hour was higher, but the exposure time was shorter due to the higher speed - so the total exposure was about the same or slightly less than conventional aircraft.
