The radiation protection guidelines of the National Aeronautics and Space Administration (NASA) are under review by Scientific Committee 75 of the National Council Protection and Measurements. The re-evaluation of the current guidelines is necessary, first, because of the increase in information about radiation risks since 1970 when the original ...

Accepting space radiation risks
Radiation and Environmental Biophysics, 2010The human exploration of space inevitably involves exposure to radiation. Associated with this exposure are multiple risks, i.e., probabilities that certain aspects of an astronaut's health or performance will be degraded. The management of these risks requires that such probabilities be accurately predicted, that the actual exposures be verified, and ...

Dosimetry is the measurement of the energy deposited in matter by various forms of radiation. In space the radiation is primarily energetic electrons, protons and heavier ions from planetary radiation belts, solar flares, and interstellar cosmic rays. Experimentally, dose is frequently obtained by summing the individual energy deposits in a solid state

Space Radiation Countermeasures
2020Different countermeasures against deleterious effects of space radiation on human health are required for galactic cosmic rays (GCR) and solar particle events (SPE). In case of SPE, efficient shielding is possible in a radiation shelter. The crew has to enter the shelter in case of increasing proton fluxes during an SPE to avoid high-dose exposures ...

Radiation hazards on space missions
Nature, 1987On the ambitious forays into space currently being contemplated, astronauts would encounter unfamiliar radiation environments. The risk of undue exposure would be diminished by spacecraft shielding.

Radiation belts, solar flares and cosmic rays are at the origin of the space radioactive environment. Electrons and protons of the radiation belts as well as protons from the Sun coronal mass ejection lead to total dose effects on electronic devices. Cosmic rays and heavy ions solar flares are responsible for heavy ions effects.

Radiation protection standards in space
Advances in Space Research, 1986Radiation protection standards for the individual exposed to ionizing radiation in his/her daily work have evolved over more than 50 years since the first recommendations on limits by the NCRP and the ICRP. Initial standards were based on the absence of observable harm, notably skin erythema, but have since been modified as other concerns, such as ...

Radiation in Space: Risk Estimates
Radiation Protection Dosimetry, 2002The complexity of radiation environments in space makes estimation of risks more difficult than for the protection of terrestrial populations. In deep space the duration of the mission, position in the solar cycle, number and size of solar particle events (SPE) and the spacecraft shielding are the major determinants of risk. In low-earth orbit missions

Space radiation protection: Destination Mars
Life Sciences in Space Research, 2014National space agencies are planning a human mission to Mars in the XXI century. Space radiation is generally acknowledged as a potential showstopper for this mission for two reasons: a) high uncertainty on the risk of radiation-induced morbidity, and b) lack of simple countermeasures to reduce the exposure.
