What materials can withstand a nuclear blast?

Hello! I was wondering what materials (and their thickness) could withstand a nuclear blast, and protect a human behind, or within the material (as in a box or whatever). Preferably a direct hit or maybe within 100m. But any it good, thank you very much.

    I dont think their are any to protect from a direct hit or within about at least 10 miles or so. But I have heard that lead could be used to protect you from the fallout.

    The only things that have been known to survive a nuclear blast,believe it or not, are cockroaches. The only things found alive after the French nuclear explosion on Bikini Atoll were cockroaches.

    Ablative materials in a heat shield, at least 30 meters thick, layered with carbon-carbon fiber reinforcements, and in the form of a cone pointed at the point of detonation. This should be backed by a meter of high strength steel, and then another 10 meters of reinforced concrete. Then a half meter of lead sheet, a Faraday cage, and finally, lots of padding to protect anybody from the shock wave.
    Here is an idea:
    Invented by a British hair stylist with no formal training in science, a
    new plastic can withstand a 10,000 degree centigrade nuclear blast.


    Starlite – A few years ago, a hair stylist in England was deeply moved
    when he learned of a fire aboard a plane that killed several children.
    His great compassion for others, in addition to the sincere love and
    kindness he felt for these children and their families, inspired him to
    develop a new flame-resistant material.
    Using just the materials available in his own small workshop, this
    British hair stylist developed a material with such heat-resistant
    qualities, it is the only substance known that can withstand the heat of
    a 10,000 degree centigrade nuclear blast. His daughter helped name the
    new material Starlite.
    During tests involving two thermonuclear blasts the Starlite plastic
    remained unharmed, and the temperature behind the 1mm sheet of Starlite
    plastic was raised by only 25 degrees.

    “Blast shelters offer some protection against blast pressure, initial radiation, heat and fire, but even a blast shelter could not withstand a direct hit from a nuclear detonation.”
    That should do for a 20 Kton fission blast at 100m. Your mileage may vary. Just a guess. You can see pictures of the Trinity test site, Japanese cities destroyed, and DOD films of tests on line.

    Hey just wanted to give you a quick heads up. The text in your post seem to be running off the screen in Opera. I’m not sure if this is a format issue or something to do with browser compatibility but I figured I’d post to let you know. The style and design look great though! Hope you get the problem resolved soon. Thanks
