Houston, we have a podcast.

Welcome to the official podcast of the NASA Johnson Space Center episode 64, Space Weather.

I'm Gary Jordan and I'll be your host today.

So in this podcast we bring in the experts, NASA scientists, engineers, and astronauts astronauts all to let you know what's going on right here at NASA.

So if you're familiar with us, you'll know that we recently just completed a five-part series on the hazards of human spaceflight.

One of those topics was on radiation.

And Dr. Zorana Patel gave us a great perspective

on what's going on and what we're doing

to learn what happens to the body when exposed

to space radiation, especially for long periods of time.

So today we're exploring what's being done right now to document radiation exposure,

not only to make sure our astronauts are healthy, but to really understand it.

So Dr. Steve Johnson is one of the senior scientists

of the Space Radiation Analysis Group.

It does not only that, but designs hardware, conducts physics modeling

and 3D modeling, and uses data to plan for future missions.

But first I wanted to start with Dr Patel, who gives us a nice overview of why studying

this is so important. So to date there are four health risks from space radiation

exposure that we identify. The first one is cancer, the risk of radiation inducedinduced carcinogenesis, and that includes epithelial cancers

and leukemia's.

And this is actually the biggest contributor to this permissible exposure limit that that's the standard we set for

our astronauts. The next one is the risk of in-flight and late CNS
