Radiation Shielding Quotes

One of the major problems with long-term deep space human flight is the requirement for radiation shielding.

The worst situation with radiation escaping is if you are downwind from it. You could virtually be on one side and not affected by the radiation. If you're on the other side and you're downwind from it, you are going to be affected.

Human beings are fragile things, and for the period of time it takes to get them to Mars and back, you have dangerous radiation from the sun and the galaxy. We have to think about issues like that.

[From uranium] there are present at least two distinct types of radiation one that is very readily absorbed, which will be termed for convenience the α radiation, and the other of a more penetrative character, which will be termed the β radiation.

It took me 45 minutes to get in all of the suits and putting all the dosimeters on me so that they knew how much radiation I got and the protective boots and everything.

When I entered the field in July 1958 I believed what they told me about radiation risks. I spent much effort reducing the dose to patients in radiology.

Research into manned spaceflight is shifting from low-Earth orbit to destinations much further away, like Mars and the asteroid belt. But society will have to invent many new technologies before it can plausibly send people to those distances.

Mars does not have an atmosphere and does not have a magnetic field today, so the planet doesn't have the protection from radiation that our atmosphere and magnetic fields provide us on Earth.

It certainly is possible to construct a moon base in such a way that crews could stay for extended periods of time.

There are allowable limits for radiation going - I mean there's radiation all around us. There's radiation from your television set. There's radiation from your computer. There's radiation actually occurring in the ground.

One of the biggest concerns about going out beyond lower Earth orbit is the radiation. We find that exercise seems to counteract a lot of the negative effects of space flight, like bone loss and muscle atrophy and cardiovascular systems issues. We exercise two hours a day on the station, which is a huge hit out of your day. It's great for staying in shape, but you know, it cuts into the productivity of the crew and if you look at how expensive it is to get a crew into space, if we can keep them healthy and have them exercise, but spend less time doing it, we can get more done.

Most of these experiments required the reduction of the cosmic ray muon flux in order to be successful, and the group necessarily became expert in the operation of deep underground laboratories.

NASA space scientists have been studying giraffe skin so they can apply what they learn from it to the construction of spacesuits.
