Technical Evaluation of the NASA Model for Cancer Risk to Astronauts Due to Space Radiation by National Research Council,Division on Engineering and Physical Sciences,Space Studies Board,Committee for Evaluation of Space Radiation Cancer Risk Model Pdf

NASA's current missions to the International Space Station (ISS) and potential future exploration missions involving extended stays by astronauts on the lunar surface, as well as the possibility of near- Earth object (NEO) or Mars missions, present challenges in protecting astronauts from radiation risks. These risks arise from a number of sources, including solar particle events (SPEs), galactic cosmic rays (GCRs), secondary radiation from surface impacts, and even the nuclear isotope power sources transported with the astronauts. The serious early and late radiation health effects potentially posed by these exposures are equally varied, ranging from early signs of radiation sickness to cancer induction. Other possible effects include central nervous system damage, cataracts, cardiovascular damage, heritable effects, impaired wound healing, and infertility. Recent research, much of which has been sponsored by NASA, has focused on understanding and quantifying the radiation health risks posed by space radiation environments. Although many aspects of the space radiation environments are now relatively well characterized, important uncertainties still exist regarding biological effects and thus regarding the level and types of risks faced by astronauts. This report presents an evaluation of NASA's proposed space radiation cancer risk assessment model, which is described in the 2011 NASA report, Space Radiation Cancer Risk Projections and Uncertainties-2010. The evaluation in Technical Evaluation of the NASA Model for Cancer Risk to Astronauts Due to Space Radiation considers the model components, input data (for the radiation types, estimated doses, and epidemiology), and the associated uncertainties. This report also identifies gaps in NASA's current research strategy for reducing the uncertainties in cancer induction risks.

Managing Space Radiation Risk in the New Era of Space Exploration by National Research Council,Division on Engineering and Physical Sciences,Aeronautics and Space Engineering Board,Committee on the Evaluation of Radiation Shielding for Space Exploration Pdf

As part of the Vision for Space Exploration (VSE), NASA is planning for humans to revisit the Moon and someday go to Mars. An important consideration in this effort is protection against the exposure to space radiation. That radiation might result in severe long-term health consequences for astronauts on such missions if they are not adequately shielded. To help with these concerns, NASA asked the NRC to further the understanding of the risks of space radiation, to evaluate radiation shielding requirements, and recommend a strategic plan for developing appropriate mitigation capabilities. This book presents an assessment of current knowledge of the radiation environment; an examination of the effects of radiation on biological systems and mission equipment; an analysis of current plans for radiation protection; and a strategy for mitigating the risks to VSE astronauts.

Evaluation of a Sex-specific Difference in Lung Cancer Radiation Risk and Approaches for Improving Lung Cancer Radiation Risk Projection (with a Focus on Application to Space Activities) by National Council on Radiation Protection and Measurements. SC 1-27 on Evaluation of Sex-Specific Differences in Lung Cancer Radiation Risks and Recommendations for Use in Transfer and Projection Models Pdf

"The study of Japanese atomic-bomb survivors exposed acutely to ionizing radiation in 1945 reported the risk of radiation-related lung cancer to be nearly three times greater for females than for males on a relative scale (similar for both mortality and incidence). The operational model for risk of exposure-induced death currently in use by the National Aeronautics and Space Administration (NASA) relies on data from the Japanese atomic-bomb survivor study. According to the NASA model, radiation-related lung cancer is the largest contributor to fatal cancer risk. The sex-specific difference in lung cancer observed for Japanese atomic-bomb survivors is used in the model, resulting in a higher estimated total cancer mortality risk for female astronauts than for male astronauts for the same level of exposure. NASA requested that the National Council on Radiation Protection and Measurements (NCRP) evaluate the risk of radiation-related lung cancer in populations exposed to chronic (protracted or fractionated) radiation, in order to investigate whether a similar sex- specific difference in lung cancer risk is observed when exposure occurs gradually over years (such as experienced by astronauts during space missions) contrasted with the acute exposure received by the Japanese atomic-bomb survivors"--

Space Radiation and Astronaut Health by National Academies of Sciences Engineering and Medicine,Division on Earth and Life Studies,Health and Medicine Division,Nuclear and Radiation Studies Board,Board on Health Care Services,Board on Health Sciences Policy,Committee on Assessment of Strategies for Managing Cancer Risk Associated with Radiation Exposure During Crewed Space Missions Pdf

Astronauts face unique health-related risks during crewed space missions, and longer-duration missions that extend to greater distances in our solar system (including to the Moon and Mars) will likely increase those risks. Cancer risks due to ionizing radiation exposure are one of these health-related risks. Assessing, managing, and communicating radiation-induced cancer risks associated with spaceflight are challenging because of incomplete knowledge of the radiation environment in space, limited data on radiation-induced cellular damage mechanisms, lack of direct observations from epidemiological studies, and the complexities of understanding radiation risk. At the request of the National Aeronautics and Space Administration (NASA), an ad hoc committee of the National Academies of Sciences, Engineering, and Medicine convened to provide advice on NASA's proposed updates to their space radiation health standard, which sets the allowable limit of space radiation exposure throughout the course of an astronaut's career. Space Radiation and Astronaut Health: Managing and Communicating Cancer Risks provides the committee's recommendations and conclusions regarding the updated space radiation health standard, NASA's radiation risk communication strategies, and a process for developing an ethics-informed waiver protocol for long-duration spaceflight missions.

Integrating Employee Health by Institute of Medicine,Food and Nutrition Board,Committee to Assess Worksite Preventive Health Program Needs for NASA Employees Pdf

The American workforce is changing, creating new challenges for employers to provide occupational health services to meet the needs of employees. The National Aeronautics and Space Administration (NASA) workforce is highly skilled and competitive and employees frequently work under intense pressure to ensure mission success. The Office of the Chief Health and Medical Officer at NASA requested that the Institute of Medicine review its occupational health programs, assess employee awareness of and attitude toward those programs, recommend options for future worksite preventive health programs, and ways to evaluate their effectiveness. The committee's findings show that although NASA has a history of being forward-looking in designing and improving health and wellness programs, there is a need to move from a traditional occupational health model to an integrated, employee-centered program that could serve as a national model for both public and private employers to emulate and improve the health and performance of their workforces.

Stress Challenges and Immunity in Space by Alexander Choukèr Pdf

This book explains how stress – either psychological or physical – can activate and/or paralyse human innate or adaptive immunity. Adequate immunity is crucial for maintaining health, both on Earth and in space. During space flight, human physiology is specifically challenged by complex environmental stressors, which are most pronounced during lunar or interplanetary missions. Adopting an interdisciplinary approach, the book identifies the impact of these stressors – the space exposome – on immunity as a result of (dys-)functions of specific cells, organs and organ networks. These conditions (e.g. gravitation changes, radiation, isolation/confinement) affect immunity, but at the same time provide insights that may help to prevent, diagnose and address immune-related health alterations. Written by experts from academia, space agencies and industry, the book is a valuable resource for professionals, researchers and students in the field of medicine, biology and technology. The chapters “The Impact of Everyday Stressors on the Immune System and Health”, “Stress and Radiation Responsiveness” and “Assessment of Radiosensitivity and Biomonitoring of Exposure to Space adiation” are available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

Safe Passage by Institute of Medicine,Board on Health Sciences Policy,Committee on Creating a Vision for Space Medicine During Travel Beyond Earth Orbit Pdf

Safe Passage: Astronaut Care for Exploration Missions sets forth a vision for space medicine as it applies to deep space voyage. As space missions increase in duration from months to years and extend well beyond Earth's orbit, so will the attendant risks of working in these extreme and isolated environmental conditions. Hazards to astronaut health range from greater radiation exposure and loss of bone and muscle density to intensified psychological stress from living with others in a confined space. Going beyond the body of biomedical research, the report examines existing space medicine clinical and behavioral research and health care data and the policies attendant to them. It describes why not enough is known today about the dangers of prolonged travel to enable humans to venture into deep space in a safe and sane manner. The report makes a number of recommendations concerning NASA's structure for clinical and behavioral research, on the need for a comprehensive astronaut health care system and on an approach to communicating health and safety risks to astronauts, their families, and the public.

Solar and Space Physics by National Research Council,Division on Engineering and Physical Sciences,Aeronautics and Space Engineering Board,Space Studies Board,Committee on a Decadal Strategy for Solar and Space Physics (Heliophysics) Pdf

From the interior of the Sun, to the upper atmosphere and near-space environment of Earth, and outward to a region far beyond Pluto where the Sun's influence wanes, advances during the past decade in space physics and solar physics-the disciplines NASA refers to as heliophysics-have yielded spectacular insights into the phenomena that affect our home in space. Solar and Space Physics, from the National Research Council's (NRC's) Committee for a Decadal Strategy in Solar and Space Physics, is the second NRC decadal survey in heliophysics. Building on the research accomplishments realized during the past decade, the report presents a program of basic and applied research for the period 2013-2022 that will improve scientific understanding of the mechanisms that drive the Sun's activity and the fundamental physical processes underlying near-Earth plasma dynamics, determine the physical interactions of Earth's atmospheric layers in the context of the connected Sun-Earth system, and enhance greatly the capability to provide realistic and specific forecasts of Earth's space environment that will better serve the needs of society. Although the recommended program is directed primarily at NASA and the National Science Foundation for action, the report also recommends actions by other federal agencies, especially the parts of the National Oceanic and Atmospheric Administration charged with the day-to-day (operational) forecast of space weather. In addition to the recommendations included in this summary, related recommendations are presented in this report.

Estimate of Space Radiation-Induced Cancer Risks for International Space Station Orbits by National Aeronautics and Space Adm Nasa Pdf

Excess cancer risks from exposures to space radiation are estimated for various orbits of the International Space Station (ISS). Organ exposures are computed with the transport codes, BRYNTRN and HZETRN, and the computerized anatomical male and computerized anatomical female models. Cancer risk coefficients in the National Council on Radiation Protection and Measurements report No. 98 are used to generate lifetime excess cancer incidence and cancer mortality after a one-month mission to ISS. The generated data are tabulated to serve as a quick reference for assessment of radiation risk to astronauts on ISS missions.
