Space radiation and cataracts in astronauts.
For over 30 years, astronauts in Earth orbit or on missions to the moon have been exposed to space radiation comprised of high-energy protons and heavy ions and secondary particles produced in collisions with spacecraft and tissue. Large uncertainties exist in the projection of risks of late effects from space radiation such as cancer and cataracts due to the paucity [corrected] of epidemiologi...
متن کاملSpace Radiation Risks for Astronauts on Multiple International Space Station Missions
Mortality and morbidity risks from space radiation exposure are an important concern for astronauts participating in International Space Station (ISS) missions. NASA's radiation limits set a 3% cancer fatality probability as the upper bound of acceptable risk and considers uncertainties in risk predictions using the upper 95% confidence level (CL) of the assessment. In addition to risk limitati...
متن کاملOperational Radiation Protection for European Astronauts
Since the early times of human spaceflight radiation has been, besides the influence of microgravity on the human body, recognized as a main health concern to the astroand cosmonauts. The radiation environment that the crew experiences during a space flight differs significantly to that found on earth due to particles of greater potential for biological damage. High-energetic charged particles,...
متن کاملSpace Radiation Organ Doses for Astronauts on Past and Future Missions
We review methods and data used for determining astronaut organ dose equivalents on past space missions including Apollo, Skylab, Space Shuttle, NASA-Mir, and International Space Station (ISS). Expectations for future lunar missions are also described. Physical measurements of space radiation include the absorbed dose, dose equivalent, and linear energy transfer (LET) spectra, or a related quan...
متن کاملControlling radiation exposure in interventional cardiology.
T he idiom " double-edged sword " describes the use of ionizing radiation in the field of medicine. Medical radiation from x-rays and nuclear medicine is the largest man-made source of radiation in Western countries and although it has benefited patients there is an associated liability or health risk that is unavoidable. A 2009 report by the National Council on Radiation Protection and Measure...
