Technical Evaluation of the NASA Model for Cancer Risk to Astronauts Due to Space Radiation
Contents:
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. 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.

Summary "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.
Technical Evaluation of the NASA Model for Cancer Risk to Astronauts Due to Space Radiation
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.
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"--Publisher's description. Notes Includes bibliographical references. We publish prepublications to facilitate timely access to the committee's findings.

You can pre-order a copy of the book and we will send it to you when it becomes available. We will not charge you for the book until it ships.
Pricing for a pre-ordered book is estimated and subject to change. All backorders will be released at the final established price. If the price decreases, we will simply charge the lower price. Applicable discounts will be extended. An ebook is one of two file formats that are intended to be used with e-reader devices and apps such as Amazon Kindle or Apple iBooks.

A PDF is a digital representation of the print book, so while it can be loaded into most e-reader programs, it doesn't allow for resizable text or advanced, interactive functionality. The eBook is optimized for e-reader devices and apps, which means that it offers a much better digital reading experience than a PDF, including resizable text and interactive features when available.
If an eBook is available, you'll see the option to purchase it on the book page. View more FAQ's about Ebooks.
