Cosmic Radiation Risk To Flight Crew

Thu Apr 19, 2001 6:05 am


What do you all think about cosmic radiation? Can anyone provide additional insight?

The following information was derived from the UAL pamphlet, "Frequently asked Questions about Cosmic Radiation". This pamphlet was published as a source of information for crewmembers to address their risks.



From what I've read, only those who fly very frequently (i.e. flight crew) are at risk. Apparently, a crewmember flying long haul routes for 20 years would have a 23.3% rate of developing cancer.

The three general hypothetical risks are:

·Cancer risk
·Genetic risks
·Risk to an unborn child.

Three factors which affect the amount of exposure:

1) Flight altitude and duration at that altitude
2) Geographic latitude of that flight
3) Stage of the solar cycle

"Aircraft usually fly at high latitude or polar routes between the U.S. and Europe or Asia; therefore these international routes are more exposed compared to domestic operations".


Your opinions, please.

Well, of course this topic is really serious, but I'd rather die from having flown twice a day, then by eating a contaminated cow or so.

Has any institution (FAA,...) ever performed investigations into this, or not? I'd sure like to know, but even when this is true, I won't stop flying. That's my opinion.

I won't stop flying, either. I'm sure the FAA has studied this, and I understand that the National Oceanic and Atmospheric Administration (NOAA) and NASA have studied the situation in some capacity as well. UAL’s medical department has studied this situation, also.

This issue pops up every now and then.
If it really was a valid issue, then we would know.
There is statistical data enough out there. Remember that every two or three seconds 24 hours a day an airliner takes off somewhere in the world.
Crew unions would negotiate extra benefits for every flight level above 10,000 feet.
The Concorde would have flown as a cargo plane only.
Boeing would never have presented their high flying sonic cruiser as the world's 8th wonder.
Astronauts would... - well, I don't know.
Etc. etc.
I don't believe in it.

For those of you that get Aviation Week, there is a good article about this on a story about polar routes.
I'm not a real aeronautical engineer, I just play one on Airliners.net.

boeing nut,

What issue? I haven't read this week's yet.

Does anyone know of the most common types of cancer? I think I've heard that skin cancer seems to be found more frequently in pilot (although research still has a long way to go). I've heard arguments on both sides of the issue. An interesting point some will argue is that since pilots are some of the most healthy people and have medical exams so frequently, they are still at less of a risk for loss of life due to cancer (because the cancer can't spread as far as it might in a normal person who isn't scrutinized healthwise on a regular basis). Just another viewpoint on the issue. Good day.

Didn't Concorde carry solar radiation monitors, and have to descend rapidly to lower altitudes if the alarms went off?

Good point about the medical exams.

There was also a good article abou this in the National Enquirer. They said that the government has irrefutable (although they didn't use such a long word) evidence that cosmic radiation is killing hundreds of flight crews a year. The flights in question are diverted to Roswell, NM and the bodies disposed of discreetly. The next of kin are then quietly eliminated.

I think there is going to be an X Files episode soon about this.
