What about radiation levels?


One of the case studies I did when at University was the radiation
levels experienced by Concorde crews (because it cruised at 60,000ft),
so it is something they've been taking into account for a very long
time.


Wouldn't some aluminium and various other bits of gubbins between the
pilot and outside at least partly offset radiation? Is the problem mainly
ionising radiation or UV?


Ionising radiation. it also affects the sensors on digital cameras so
Recliner needs to check his for excessive pixel loss. TV crews who do a
lot of flying tend to invest in special cases with a thin lead lining.
Causes havoc at some check-ins.
