Overcoming The Radiation Problem

One of the hurdles of space travel is protecting the astronauts from
ultraviolet radiation, including the cosmic and gamma rays from the sun and
outer space, which puts them at risk for cancer and death.

To counteract the potentially lethal effects of space radiation, Israeli
company StemRad has developed a radiation vest, customized for each
astronaut and designed to shield vital human tissue, such as reproductive
organs, lungs, and stem cells, from radiation exposure.

The lightweight vest is called the AstroRad Radiation Shield and, according
to some sources
,
could be tested as early as next year, when the Orion will be making its
first trip around the moon.

This safety measure will reportedly offer the same amount of protection as
the other radiation-proof idea NASA is planning to use: a shielded "safe
room" installed aboard the Orion. Essentially a storm shelter, this cabin
will safely house the astronauts in the event of a solar flare storm.

Other options include anti-radiation drugs which could be administered to
reverse some of the effects of severe radiation exposure.

The first sentence makes absolutely no sense whatsoever. Ultraviolet radiation is not the issue. That is stopped by the hull. The problem radiation from the Sun is photons, not gamma rays and cosmic rays do not come from the Sun, they come from every direction. Neither cosmic nor gamma rays are ultraviolet radiation.

Whoever wrote this sentence has no idea what they're talking about.

I saw the news reports on this, and am a bit skeptical myself. A vest
is more likely to *increase* radiation dosage (due to secondary
radiation) from cosmic rays. It might be useful against lighter ions,
though.
