[508] A COMPARISON OF COCKPIT UV EXPOSURE IN SEVERAL MEDIUM ALTITUDE AIRCRAFT

摘要

INTRODUCTION: Ultraviolet radiation exposure of aircrew in aircraft cockpits are not well characterized. Crew positioning, time of day, and altitude are ail factors of UV exposure. Here, we describe the relative cockpit exposures of six different aircraft. METHODOLOGY: Aircraft surveyed included the Beechcraft 1900C, the BAe Hawk, the C-130J, the BAe RJ, the Dornier Alpha Jet, and the Grob G115. These aircraft represent a diverse portfolio of capabilities, and most of them operate at medium altitudes where UV exposure becomes a concern. Each of these aircraft were measured in at least two different locations and both total energy and wavelength of the radiation were characterized. Most of the aircraft values were measured with a point UV source on the ground, and total transmittance of the UV energy was evaluated. In one aircraft, a volunteer pilot wore an attachable UV device and placed it on various predetermined areas on his body and around the cockpit.
