Laser Beam Hazard for flight personnel

Nominal Hazard Zone in Medical Laser Centers

Control the laser beam hazards for class IIIB and IV laser is concluded: engineering and executive controls. In executive control, when laser beam enters to the free space, the controlled area must be identified to protect people and control the radiation exposure limits. Given the fact that the laser light of the laser is entering the environment, the identification of the area under control i...

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...

Selection and training of personnel for space flight.

T H E ACCOMPLISHMENT of powered flight into space will depend not only on the development of suitable cabins, propellants and engines, but also on the equally important issues of selection and training of space crews. I t is the purpose of this report to formulate, in the light of presently available information and opinion, a tentative outline of crew requlirements for spaceships and then to i...

Hazard Identification on a Single Cell Level Using a Laser Beam

This research shows a novel method for hazard identification of a chemical and UV light on a single cell level with a laser probe beam. The laser probe beam was passed through interface of cell membrane/culture medium of a cultured human hepatoblastoma cell line HepG2. Deflection of the laser probe beam, which was induced by changes in concentration gradients due to the active materials movemen...

Laser and Its Hazard Potential

Laser-induced eye injuries have been reported more and more often in the past years, yet the laser is not a modern invention. Based on stimulated emission, the wavelength, energy dose and pulse duration of the laser are the determining factors for its possible hazard potential. The eye, which is the most vulnerable body part for laser radiation, can be affected. As medical treatment is discusse...
