Mars may be a literal frozen desert, but while it looks inhospitable, its water activity level is just below our threshold for life at about 0.537. (syfy.com)
Cosmic radiation is the most serious risk that will be encountered during the planned missions to the Moon and Mars. (bvsalud.org)

The National Council on Radiation Protection and Measurements has a 0.5 mSv recommended monthly radiation limit during pregnancy. (cdc.gov)
The levels measured by Chang'e 4, in fact, "agree nearly exactly" with measurements by a detector on a NASA orbiter that has been circling the moon for more than a decade, said Kerry Lee, a space radiation expert at Johnson Space Center in Houston. (apnews.com)

Nislow had spent years leading a team investigating how to protect people from the deadly effects of cosmic radiation. (nsnews.com)
Of unknown origins, these rays emit deadly levels of carcinogens onto (and into) any living organism that comes into its path. (thrillist.com)
Polluted water can be a source of deadly levels of arsenic [ 4 ]. (who.int)

Radiation protection is part of the fields of the ILO's action on the protection of workers against sickness, disease and injury arising out of his employment as mandated by the Organization's constitution. (ilo.org)
The ILO's activities on radiation protection cover the protection of workers against both ionizing and non-ionizing radiations. (ilo.org)
The ILO has developed over the years a number of policy instruments on radiation protection which include Conventions and recommendations (e,g. (ilo.org)
The ILO encourages and promotes the active involvement of employers' and workers' organizations in the development of international standards on occupational radiation protection and in the implementation of the occupational radiation standards at both the national and enterprise levels. (ilo.org)
The study of naturally-occurring radiation and its associated risk is one of the preoccupations of bodies responsible for radiation protection. (radioprotection.org)
Even back then the International Commission on Radiation Protection thought that model might not be correct but they adopted it because, on the available evidence it would Not Underestimate the risk of harm. (joannenova.com.au)
The primary quantity of interest in radiation protection is dose equivalent. (troxlerlabs.com)
The U.S. Environmental Protection Agency's (EPA) proposed rule for radiation doses to future generations would overturn all established principles of public health protection, according to the Institute for Energy and Environmental Research (IEER). (ieer.org)
Though plenty of work is being conducted , radiation protection technology is a long way behind other aspects of rocketry. (space.com)
Only one-third of physicians had received a radiation protection course during their undergraduate study or in the workplace. (who.int)

We are finding that some crewmembers may have exposure to cosmic radiation that is higher than what is recommended, and thus may be at greater risk for possible health effects. (cdc.gov)
Radiation can be classified according to the effects it produces on matter, into ionizing and non-ionizing radiations. (ilo.org)
To prevent genetic damage to life, the atmosphere's stratified structure reduces the destructive effects of sunlight, UV radiation, solar wind, and cosmic rays. (javatpoint.com)
is unit to measure health effects of radiation on the human body. (euronuclear.org)
It so happens that some types of radiation produce greater effects on the body than others for the same amount of energy absorbed (absorbed dose). (troxlerlabs.com)
This study is of crucial importance not only as risk factors for human space exploration, but also as fundamental effects of radiation on the components of the human body. (bvsalud.org)
However, there is presently a paucity of information on the effects of space radiation on cognitive flexibility in female rodents. (bvsalud.org)
Radiation exposure also altered the magnitude and/or nature of practice effects. (bvsalud.org)
Moreover, exposure to radiation leads to multiple performance decrements, including loss of practice effects, an increase in anterograde interference and reduced ability or unwillingness to switch attention. (bvsalud.org)

They recommend effective dose limits of 20 mSv /year averaged over 5 years (that is, a total of 100 mSv in 5 years) for radiation workers and 1 mSv/year for the public. (cdc.gov)
Scientists at The Johns Hopkins University Applied Physics Laboratory found that the effective dose per screening was 1.58 microrems of radiation , while a researcher at the National Institute of Standards and Technology, an agency of the U.S. Department of Commerce, said an adult would be exposed to 2.4 microrems of radiation per scan . (politifact.com)

The autocorrelation function of the number of correctable errors per month shows significant levels of correlation up to 7 months. (mvdirona.com)
Their hypothesis was based on a strong correlation between levels of cosmic radiation and cloud cover - that is, the greater the cosmic radiation, the greater the cloud cover. (proudtobecanadian.ca)
