Women were more likely to develop lung cancer than men, suggesting a greater sex-based vulnerability to harmful radiation.
Although meant to minimize risks to human health, the proposed new limits would still be exceeded by any conceivable near-future crewed voyage to Mars.
As particles from the sun and high-energy cosmic radiation stream constantly into their bodies, astronauts are always in danger. Radiation can cause serious health problems if it is not controlled.
The proposed guideline would give all astronauts the same radiation limit, regardless of age and sex.
A blue-ribbon panel has endorsed NASA’s plans to revise its standard for exposing astronauts to radiation in a way that would allow women to spend more time in space.

Moonwalkers take heart—China’s Chang’e 4 lander has made the first detailed measurements of the intense radiation that blasts the lunar surface and found that it’s safe for human exploration. The results give researchers a better idea of how much protective shielding future crews will need.
If the Mars Perseverance Rover was lifting off from Cape Canaveral at almost any other time, UNLV Professor Elisabeth “Libby” Hausrath would have had a front-row seat.

There are at least a dozen trials worldwide testing low-dose radiation therapy, or LDRT, as a treatment for pneumonia related to Covid-19, some spurred by the same historical data Calabrese and colleagues scoured years ago. The theory: Targeted radiation to the lungs will halt the out-of-control inflammation responsible for the devastating pneumonia that bookends the course of some Covid-19 patients.
Sending humans to Mars could leave astronauts with neurological problems, according scientists who studied mice in conditions which they claimed replicate deep space.
