FAQ. Is it safe to fly at night? With proper planning there is no reason a pilot cannot safely accomplish a flight at night. Pay particular attention to picking a safe route, particularly in a single engine airplane or helicopter.
Are pilots more prone to radiation?
The National Council on Radiation Protection and Measurements reported that aircrew have the largest average annual effective dose (3.07 mSv) of all US radiation-exposed workers. Other estimates of annual aircrew cosmic radiation exposure range from 0.2 to 5 mSv per year.
