Rogerio Animal, Branco Simonetti - Can You Dig It (Original Mix) [303Lov...

well if they get their way, you may need to ask yourself, the question how deep does a nuclear bunker need to be, "can you dig it", deep enough by hand, to to survive a nuclear blast?, In terms of necessary thickness, to prevent nuclear radiation from infecting you:
4 inches of lead
10 inches of steel
24 inches of concrete
36 inches of packed dirt
72 inches of water
110 inches of wood
Rule of thumb is about 170 kg of mass per square foot of shielding.
In terms of being underground, 36 inches (3 feet) of well-packed dirt will shield you from the harmful effects, and probably 48 to 60 inches (4 feet to 5 feet) of loose/shovelled on dirt will shield you.
In terms of nuclear blast energy itself, it really depends on distance; you basically have no chance in direct proximity (within 1–3 miles or so) to a detonating warhead in a standing structure. If underground, you still want to be at least a mile or two away. if you want to know more try, http://www.nuclearsecrecy.com/nukemap/,  There are many, many different factors at play in this scenario. Is it an air burst or a ground burst? (If the weapon is being used to destroy a soft target, such as a city, the warhead would be detonated in the air so the shock wave from the blast could reflect off the ground to do more damage. A ground burst is when a warhead strikes a target in or very close to the ground. This minimises overall the diameter of the damage, but focuses it to a more specific area. You would most likely see a ground strike on say a missile silo or a bunker.). In neither case would you be able to survive above ground. In both cases, within the first few milliseconds, the area you are standing in would be flooded with massive amounts of radiation from across the spectrum. Within the 1 km radius you would be exposed to roughly 5000 rems (that is a measurement of damaging radiation to humans) which is equivalent to around 50,000 chest x-rays, which would be 100% fatal. Also, you would still be well within the fireball of the blast which produces heat in excess of the heart of the sun. In addition, your body would be subjected to 200 psi of over pressure. What that means is, every square inch of your body would have an additional 200 pounds of pressure pressing down on it. Think of a board that is 12 inches long by 12 inches wide. In this case, the 144 square inches of the surface of that board would have 28800 pounds of pressure crushing down on it.  Now, you may ask, what if I were underground? The blast would be roughly equivalent to a earthquake that registered 6.5 on the Richter scale. What that means is, even underground at a reasonable depth, there is a very good chance that the structure that you were in would collapse. In addition to that, radiation still will penetrate the ground. Halving factors or half value layers basically means how much stuff do you have to put between you and the radiation source to half the amount. Good old fashion dirt (roughly) will reduce in half the amount of radiation every 9 cm. So to be at a safe level of radiation exposure, you'd roughly need to be covered by 144 cm of earth. So, theoretically, if you were in a subway station underground that did not collapse due to the seismic shock of the blast, and it was airtight you may be safe, but there have been survivors from relatively low yield one, around 300 meters , so good for you Ms. Akiko Takakura (you dodged a giant bullet you were very lucky), was 20 years old when the [nuclear] bomb fell. She was in the Bank of Hiroshima, 300 meters away from the hypocenter. Ms. Takakura miraculously escaped death despite over 100 lacerated wounds on her back. She is one of the few survivors who was within 300 meters of the hypocenter, but that was sheer luck, normally she would have been toast as, standardz, hahaha :( #edio
