Orion's orientation during flight affected radiation exposure, which dropped by half when the spacecraft made a 90-degree turn flying past the inner Van Allen belt.
Airline crews flying long-distance high-altitude routes can be exposed to 2.2 mSv of extra radiation each year due to cosmic rays, nearly doubling their total exposure to ionizing radiation. Average annual radiation exposure ( millisieverts )
There are three fundamental ways to reduce exposure to ionizing radiation: [32] increasing the distance from the radiation source; reducing the exposure time; shielding (i.e.: a physical barrier) Shielding is a plausible option, but due to current launch mass restrictions, it is prohibitively costly.
Disks Flown on STS-40 STS-40 Cargo Bay configuration. G-616, formally known as GAS canister #G-616: The Effect of Cosmic Radiation on Static Computer Media & Plant Seeds Exposure to Microgravity was an experiment flown on the Space Shuttle as a self-contained experiment, as part of STS-40.
Flying 12 km (39,000 ft) high, passengers and crews of jet airliners are exposed to at least 10 times the cosmic ray dose that people at sea level receive. Every few years, a geomagnetic storm permits a solar particle event to penetrate down to jetliner altitudes. Aircraft flying polar routes near the geomagnetic poles are at particular risk.
Exposure to radiation causes chemical changes in gases. The least susceptible to damage are noble gases, where the major concern is the nuclear transmutation with follow-up chemical reactions of the nuclear reaction products. High-intensity ionizing radiation in air can produce a visible ionized air glow of telltale
Historical milestones in cosmic ray astronomy inclue Victor Hess's discovery of cosmic rays during balloon flights in 1912; [6] the identification of new subatomic particles like the positron and muon in the 1930s, expanding our understanding of particle physics; [7] Pierre Victor Auger's discovery of extensive particle showers from cosmic ray ...
