NASA FUNDS SPACE RADIATION RESEARCH PROPOSALS

NASA selected 21 space radiation research proposals for funding.
Approximately $19 million will be spent on the research to support the
Vision for Space Exploration.

The goal of NASA's Space Radiation Program is to ensure humans can safely
live and work in space. Safely means acceptable risks are not exceeded
during crews' lifetime. Acceptable risks include limits on post and
multi-mission consequences, such as excess lifetime fatal cancer
vulnerability.

Exposure to radiation during space flight is unavoidable. Space radiation
penetrates the crew, spacesuits, spacecraft, habitats, and equipment. The
interaction of radiation with materials changes both; and the interaction
with living organisms leads to potentially harmful health consequences. The
consequences include tissue damage, cancer, cataracts, electronic upsets,
and material degradation.

Space radiation is distinct from terrestrial forms. Space radiation is
comprised of high-energy protons, heavy ions and their secondaries produced
in shielding and tissue. Since there are no human epidemiological data for
these radiation types, risk estimation is derived from mechanistic
understanding. The estimates are based on radiation physics, molecular,
cellular, and tissue biology related to cancer and other risks.

NASA received 115 responses to the request for proposals issued on August
24, 2004. Proposals were peer-reviewed by scientific and technical experts
from academia, government, and industry. The 21 proposals will seek to
reduce the uncertainties in risk predictions, including cancer, degenerative
tissue damage, cataracts, hereditary, fertility, and sterility. They also
cover acute risks and development of effective shielding or biological
countermeasures for them.
