How far can a mushroom cloud be seen from?
The flash could be seen from 1,000km (630 miles) away. The bomb’s mushroom cloud soared to 64km (40 miles) high, with its cap spreading outwards until it stretched nearly 100km (63 miles) from end to end. It must have been, from a very far distance perhaps, an awe-inspiring sight.
How far away can a nuke be seen?
combined with the observations of Major Charles Sweeney that the height of the flash, off the cirrus clouds over Nagasaki, was “at least 6 miles (or 31,000 feet) [above the explosion]” giving a refraction-free visibility for such a reflected flash as about 230 miles or 370 km.
How far away from a nuclear bomb is safe six feet?
Survive DURING This will help provide protection from the blast, heat, and radiation of the detonation. When you have reached a safe place, try to maintain a distance of at least six feet between yourself and people who are not part of your household.
How high do mushroom clouds go?
Mushroom clouds formed as a result of nuclear explosions can go thousands of meters in the sky, easily surpassing the height of Mt. Everest – the tallest mountain peak in the world. The strength of nuclear explosions is measured in Kilotons and Megatons of TNT.
What was the mushroom cloud from the atomic bomb?
Mushroom cloud from the atomic bombing of Nagasaki, Japan on August 9, 1945. A mushroom cloud is a distinctive pyrocumulus mushroom-shaped cloud of debris/smoke and usually condensed water vapor resulting from a large explosion.
How far away can we see a plume of nuclear radiation?
On the other hand, after doing some research, they state nuke explosions can be seen from 600 miles distance, but 600 miles gives a curve of 71km, I don’t think we can see a plume, unless the earth is flat. You have ignored the mirage and refraction effects that have commonly been noted in these examples.
What is the distribution of radiation in a mushroom cloud?
The distribution of radiation in the mushroom cloud varies with the yield of the explosion, type of weapon, fusion/fission ratio, burst altitude, terrain type, and weather. In general, lower-yield explosions have about 90\% of their radioactivity in the mushroom head and 10\% in the stem.
