Pilots and engineers are pretty concerned about the implications. Some of the damage may not be immediately apparent, but long term exposure could cause premature wear and damage to parts.
Never mind the wear and tear on the aircraft parts ... even more alarmingly, there's talk of exposure to the 'fallout' causing serious damage to human body parts - notably the lungs!!
