Background radiationBackground radiationRadiation that is always in the environment. Observations used as direct input to predict radiation exposure at the Earth, on the Moon, Mars and in interplanetary space environments. "We really need to know more about the radiation environment on the Moon, especially if people will be staying there for more than just a few days," says Harlan Spence, a professor of astronomy at Boston University.To carefully measure and map the Moon's radiation environment, NASA is developing a robotic probe to orbit the Moon beginning in 2008. LRO is a key part of NASA's Robotic Lunar Exploration Program, managed by the Goddard Space Flight Center.One of the instruments onboard LRO is the Cosmic Ray Telescope for the Effects of Radiation (CRaTER). Vacuum and temperature NASA can handle; spacesuits and habitats provide plenty of air and insulation. Lunar Reconnaissance Orbiter will hunt for water.Hitchhikers Guide to the Moon -- (Science@NASA) NASA plans to put a laser in orbit around the Moon to map its surface for future explorers.Can People Go To Mars? Igor Mitrofanov, a scientist at the Institute for Space Research and the Russian Federal Space Agency, Moscow, offers a grim answer: "Both are worse. How dangerous is it out there? ► Calculation of organ doses on the surface on the moon for an astronaut in an EVA suit. The majority of background radiation occurs naturally and a small fraction comes from man-made elements. These measurements need to be complemented by surface measurements.Models and simulations that exist describe the approximate radiation exposure in space and on the lunar surface. "The first global mapping of neutron radiation from the Moon was performed by NASA's Lunar Prospector probe in 1998-99. Beside the continuous exposure to galactic cosmic rays (GCR), which increases the risk of cancer mortality, exposure through particles emitted in sudden nonpredictable solar particle events (SPE) may occur. Naturally occurring radioactive minerals in the ground, soil, and water produce background radiation. The majority of background radiation occurs naturally from minerals and a small fraction comes from man-made elements. Called the Lunar Reconnaissance Orbiter (LRO), this scout will pave the way for future human missions not only by measuring space radiation, but also by hunting for frozen water and mapping the Moon's surface in unprecedented detail. The knowledge on the radiation exposure at the lunar surface is exclusively based on calculations applying radiation transport codes in combination with environmental models. On Earth, the contribution to the annual terrestrial dose of natural ionizing radiation of 2.4 mSv by cosmic radiation is about 1/6, whereas the annual exposure caused by GCR on the lunar surface is roughly 380 mSv (solar minimum) and 110 mSv (solar maximum). particle radiation. The solar wind is a steady plasma emission from the Sun consisting of equal numbers of ions and electrons embedded in a magnetic field. Very recently some data were added by the Radiation Dose Monitoring (RADOM) instrument operated during the Indian Chandrayaan Mission and the Cosmic Ray Telescope (CRaTER) instrument of the NASA LRO (Lunar Reconnaisance Orbiter) mission. is present on Earth at all times. A very high level of radiation exposure delivered over a short period of time can cause symptoms such as nausea and vomiting within hours and can sometimes result in death over the following days or weeks. ► Calculation of the radiation environment on the moon using numerical methods. Since it is necessary to verify/validate such calculations with measurement on the lunar surface, a description is given of a radiation detector for future detailed surface measurements. The lunar surface itself is radioactive!So which is worse for astronauts: cosmic rays from above or neutrons from below? The absence of magnetic and atmospheric shielding allows cosmic rays of all energies to impinge on the lunar surface. Called the Lunar Reconnaissance Orbiter (LRO), this scout will pave the way for future human missions not only by measuring space radiation, but also by hunting for frozen water and mapping the Moon's surface in unprecedented detail. -- (Science@NASA) Space radiation between Earth and Mars poses a hazard to astronauts.
The only efficient measure to reduce radiation exposure is the provision of radiation shelters.Measurements on the lunar surface performed during the Apollo missions cover only a small energy band for thermal neutrons and are not sufficient to estimate the exposure.
