In-Flight Radiation

In-flight radiation: counseling patients about risk.

BACKGROUND At the high altitudes, which are the domain of commercial airliners, cosmic-ray exposure rates are hundreds of times greater than at ground level. If this radiation originated at a regulated industrial or medical facility, many frequent flyers would receive annual exposures in excess of the present legal limit applicable to members of the public. For pregnant travelers, the fetus is ...

Radiation Hazards and Manned Space Flight.

T HE POTENTIAL medical hazards of man's venture into space will span a number of disciplines in regard to the pathology and deranged physiology to which the human body may be subject in travel beyond the earth's atmosphere. Not the least hazard is that having to do with the effects of radiation to be encountered in free space. This problem is one which is receiving considerable attention from a...

Radiation Hazard of Relativistic Interstellar Flight

From the point of view of radiation safety, interstellar space is not empty. Neutral and ionized interstellar gas and cosmic rays consisting of H and He-nucleons constitute radiation hazard aboard relativistic interstellar ships. Relativistic aberration of cosmic rays is evaluated and radiation doses from oncoming relativistic flow of interstellar gas and cosmic rays are estimated. Necessary sh...

Radiation dosage in flight through the Van Allen belt.

A B O U T ten years ago, when avialion medicine developed a seri,ous interest in the problem of cosmic ray ,hazards in flight at the top of and outside the atmosphere, it became common practice to express cosmic ray intensities in terms of tissue ionization dosages, that is, in roentgens equivalent physical ( rep) . This expedited ~he interpretation of the ~;lata of the physicists inasmuch as e...
