Space Radiation Dosimeter SSJ* for the Block 5D/Flight 7 DMSP (Defense Meteorological Satellite Program) Satellite: Calibration & Data Presentation


Book Description

The DMSP/F7 satellite carries, in addition to weather monitoring devices, a number of instruments that measure the space environment for the purpose of scientific study. These are an auroral imaging device, precipitating electron and ion detectors, a thermal plasma analyzer, a fluxgate magnetometer, and a space radiation dosimeter. Together, these provide a strong tool for analyzing the high latitude, near-Earth, magnetospheric environment. This report has been prepared to facilitate the use of the data from one of these instruments, the space radiation dosimeter, and to show the data can be used to obtain both dose and flux measurements of high energy Relativtic electrons and protons at low altitudes. The report includes: a description of the DMSP/F7 orbit; a description of the space radiation dosimeter and the data it returns; the method by which dose is determined; the method by which flux is determined; and a discussion of the use of high threshold energy proton and ion induced star counts. Appendices A and B present the response of the dosimeter to electron bremsstrahlung and a list of the interactive routines available at AFGL for data analysis.

Terrestrial Space Radiation and Its Biological Effects


Book Description

This volume is based on the proceedings of an Advanced Study Institute (ASI) sponsored by the North Atlantic Treaty Organization (NATO) held October 1987 in Corfu, Greece. The Institute received financial support from the National Aeronautics and Space Administration, U.S.A. Armed Forces Radiobiology Research Institute, U.S.A. Department of Energy, U.S.A. Deutsche Forschungs-und Versuchanstalt fur Luft und Raumfahrt e.v., Kaln, Germany The advent of the shuttle era is providing fresh impetus for large space ventures such as communication centers, solar power stations, astronomical observatories, orbiting factories, and space based radar. Such ventures will rely heavily on an extensive and prolonged human presence in space doing in-orbit construction, maintenance, and opera tion. Among the advantages of location in space are the near zero gravity environment, commanding location, and the reception of solar energy and astronomical signals unattenuated by the atmosphere. Central to long-term manned space missions are the problems associated with the effects of exposure to ionizing radiations on humans. Manned space mis sions in the past have encountered relatively benign radiation environ ments because of their very short duration and orbit configuration. However, crew stay time of up to a year has been recently achieved by the Soviet space program; and Mars missions lasting several years are under serious consideration.




High-Energy Radiation Background in Space
