How far do you need to be from a nulcear bomb in order not to be fried, sizzled, vaporized, burnt to a crisp, blown to china, totally destroyed---well, you get the picture--How far? Deep?

Nuclear bombs come in different sizes and types. They come all the way from the equivalent of a few tons of TNT (would you want to be next to a railroad car of TNT going off? Not me!) to thermonuclear bombs which are over 100 megatons of TNT ( 100,000,000tons!!!)
There are maps of "Zones of Lethality" for each size, telling what percentage of people will die in that area.
The sneaky thing is the radiation cloud, like Chernobyl, the Russian nuclear explosion. There are many hundreds of square miles of land, and cities, that are not safely habitable. Some radioactive isotopes last a very long time, and then decay into another radioactive isotope. These lands may not be safe for thousands of years!! These depend on prevailing wind conditions. Chernobyl's covered most of Europe. It was downplayed to avoid panic. Milk had strontium 90 for some time. It replaces calcium, is radioactive, and causes cancer.
There is not simple answer, except that thank God there has never been a nuclear war, because radioisotopes blown miles high by many thermonuclear bombs have long been calculated, along with debris, to be able to blot out the sun, and cause a "nuclear winter," possibly extinguishing most life on earth.
With nuclear bombs above ground, or at all, "safe" is a word that is very difficult to use.
Plus the EMP, electromagnetic pulse, of a large nuclear explosion will disable all electronics anywhere near by causing a massive power surge.
Massive induced currents. Some bombs and devices are designed expressly to do that.
Some conventional bombs are loaded with radioactive material that will scatter and kill and sicken, a dirty bomb.
Not fun to think about, huh? People that are cheering for the USA to use nukes in Iran had better think. They will kill us all.
See the movie: "On the Beach."

I bear in mind a Sgt had instructed me that the Marines would desire to run 3 miles in 18:00 to flee a nuclear explosion (he replaced into an fool) a million Mega Ton blast ~ you will would desire to be a minimum of seven a million/2 miles away to be "ok" as debris can nonetheless kill you. Any closer than which would be obliteration, the two from the explosion, fallout, each and all of the oxygen being sucked out of the section, and what somewhat kills you ~ shockwave. 25 Mega Ton blast ~ something exterior of 30 miles would be "ok" any closer and you're ineffective or dying.

10 or 11 feet to be safe...

depends on power or TNT(tri nitro tolvin)

If in doubt--keep running!

Far enough that you can say, "What was that?"
