Flew to the azz crack of Bama and back(and boy are my arms tired, nyuk nyuk).
Took my Geiger counter. On the tarmac it was reading 8 - 12 mREMs. That's what I've gotten at home and at Surry Nuclear Power. When we got up to cruising altitude it was 255 mREMS. The flights weren't long, ORF to ATL to PNS. Basically get up, get down. Are flights that are longer, up higher? If so, that can't be good for the frequent flyer.
