There is quite a good summary by the UK National Radiological Protection 

Board at the following URL

It as my understanding that doses to aircrew could not be accurately 

estimated using simple passive detectors such as TLDs.   Instead special monitoring 

equipment has been developed by the NRPB which is carried on the aircraft to 

provide dosimetric information and that by using different routes/flight 

paths/altitudes it is possible to estimate the doses to aircrew.
