How deep can a human survive underground?
This limits habitation to about 3500 meters in a seismically stable area. Assuming surface conditions are hazardous or downright toxic, ventilation from surface points would be at least as costly as recycling used air through CO2 scrubbers to detoxify and re-oxygenate it.
How far under ground do you need to be to survive a nuke?
Packed earth insulates against radiation and blast waves, but don’t go deeper than 10 feet; if your exits (make two) become blocked in the blast, you may need to dig yourself out.
How far underground Do you need to be to avoid radiation?
About 3 feet down underground, or some equivalent shielding. In order to get a reasonable protection factor, you want to try for 10 “halving thicknesses ” of mass between you and any source of gamma radiation. That means you need about 36 inches of packed earth or 24 inches of concrete on all sides, including above.
Can we live underground forever?
Yes we can, but not forever if all life support systems are mechanical. The more that can be made with minimal moving/mechanical parts, the longer humans could remain underground. Underground bunkers or caverns need ventilation, climate control, ground water removal, food production, and light and energy sources.
How deep can humans survive in a mine?
Less than 2 miles of depth Oxygen/Carbon Dioxide Based Limit Underground there’s very limited life able to convert our wastes ($CO_2$, urine, & feces) back into forms that we can use. Although we have many mines located a mile or more below ground, all of these require air exchange to keep humans alive.
Why can’t we live below ground?
Underground there’s very limited life able to convert our wastes ($CO_2$, urine, & feces) back into forms that we can use. Although we have many mines located a mile or more below ground, all of these require air exchange to keep humans alive. Active
Why are we so afraid of the underground?
“The human mind is naturally predisposed to fear underground spaces, which it associates with dark, small, cavernous environments and a danger of being buried alive,” says Suarez.
