A French court has for the first time recognized cosmic radiation as a contributing occupational factor in a flight attendant’s breast cancer, alongside passive smoking and years of night work. The landmark ruling could open the door to similar claims from other aircrew, as research continues to link long-term high-altitude flying with elevated exposure to radiation-related cancers. The BBC reports: Sophie Lainault, a 59 year-old former stewardess on Air France, sought to have her cancer recognized as an occupational disease, brought on by conditions at work.
