Radius of a solid sphere to contain nuclear weapons?

Here's a fun question that I have always wondered. Suppose you have a steel ball solid. Suppose that at the center of this sphere is a cavity large enough to contain a nuclear bomb. What is the radius of the steel sphere should be such that a person standing next to the field when the nuclear bomb explodes the blast did not realize / Do not hurt? On the other hand, suppose that the nuclear weapon has a resistance of 20 tons metric tons (megatons).

You have to calculate the overpressure of the blast about 20 meters may be one or two meters from the center, then calculate the amount of steel to withstand the pressure. I think it would be hundreds of feet underground tests is that nuclear weapons in the desert have a few thousand feet depth by only a few kT from Wikipedia: The areas surrounding the name of rock Radio Melt cavity 4-12 m / kt ^ 1 / 3 crushed zone 30-40 m / kt third zone cracked 80-120 ^ m / kt ^ third irreversible deformation zone 800-1100 m / kt ^ 1 / 3 Then do an experiment using these numbers. The cube root of 20 000 is 27, so a pump 20mt about 27 times as a bomb on the rock 1kT starts when underground. Let's say that the cracking of the steel is between the strain and rock irreversible cracks. This would be about 500 m / kt ^ 1 / 3 or 13.5 thousand meters of your pump. You do not need a steel tank of 27 km in diameter (plus or minus a couple of orders of magnitude) to contain all that nuke. A ball of 27 km in diameter steel would weigh about 8000 kg / m ^ 3. Therefore, there would be little ground containment about 10 ^ 13 kg or approximately 110 billion tons. It would be easier to drop the ball in his enemy (If You Can do it and lift) that would Make Him jump. If I remember correctly, was a bomb Tsar Bomba 65 Mt and caused third degree burns 100 km if it could make the steel container to protect against 20mt pump, you should be in good shape compared to someone who has been without protection. Of course, most coconut nuclear weapons were not much larger than 1MT and our nuclear weapons are a little smaller, because distribution systems have been much more specific, if you can save if you need steel to protect someone from a more type nuke.
