Exposure Hill [SEP] continent
Exposure Hill
Exposure Hill () is a low hill at the southwest end of Gair Mesa, in the Mesa Range, Victoria Land, Antarctica. This topographical feature was so named by the northern party of the New Zealand Geological Survey Antarctic Expedition, 1962–63, because the west side of the hill has a noteworthy exposure of light colored sandstone. The hill lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
source of the radiation is a medical X-ray machine, a nuclear power plant or radiation in space. The degree of the harmful effect depends on the length of exposure and the radiation's energy density. The ever-present radiation belts extend down to the altitude of manned spacecraft such as the International Space Station (ISS) and the Space Shuttle, but the amount of exposure is within the acceptable lifetime exposure limit under normal conditions. During a major space weather event that includes an SEP burst, the flux can increase
