ANS is hosting a virtual Graduate School Fair on Friday, November 19, from 3:30 p.m. to 6:30 p.m. (EST). The goal of the event is to help prepare the next generation of nuclear professionals and to keep early career and seasoned experts at the top of their game.

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.

Left unchecked, radiation can trigger all sorts of health issues, most notably boosting an astronaut's danger of developing cancer. So, when NASA plans missions, the agency uses a radiation exposure cap to determine how long astronauts can stay in space.

The proposed guideline would give all astronauts the same radiation limit, regardless of age and sex.
