Many pseudoscientific sources claim that Harappa and Mohenjo-Daro were wiped out by some kind of nuclear weapons.
Massive walls are fused together,but there is no indication of a volcanic eruption. Radioactive skeletons have also been found.

A heavy layer of radioactive ash was discovered in Rajasthan. Scientists have unearthed an ancient city where evidence shows an atomic blast dating back thousands of years, from 8,000 to 12,000 years, destroyed most of the buildings and probably a half-million people. One researcher estimates that the nuclear bomb used was about the size of the ones dropped on Japan in 1945.

These stories always seemed strange to me. I suppose that in the light of the nuke hoax theory they may be viewed as an attempt to construct a sort of nuclear mythology. The blatant Hiroshima parallel speaks for itself. I wonder is it possible to measure the real radiation levels there.

I have heard some of these stories. It might be an attempt to explain away the melted glass rocks that are found in such places. After claiming that the sand in Alamogordo was melted in the Trinity test, forming Trininite, they had to have an explanation when others started pointing out that such rock could be found in other places, and in great abundance. Like the Libyan dessert.

It's another example of myths surrounding radiation. I think FirstClassSkeptic pointed out first that the radiation scare is a way to keep people away.

The point is that dangerous radiation has a short half-life. (Natural uranium has a half-life estimated in millions or billions of years; I forget the quoted figures.) Its radioactivity is barely detectable. Dangerous isotopes are supposed to have short half-lives, so the victims get zapped even if there isn't much of the stuff around.

Therefore there is a contradiction between these two things!

Something with a half-life of a week will decay in 10,000 years to 1/2^520,000 of its first week's intensity - too tiny to be output by Microsoft's scientific calculator. It has more than 100,000 zeroes after the decimal point!

There was supposed to be a natural uranium 235 explosion in Gabon in 1972; I've heard this attributed to slow build-up of (I assume) U235 by some biological action. Sounds like part of the French contribution to nuclear bullshit.

Modern India sure looks like it's been hit by a few. That is, if nuclear bombs were to exist.

Sounds like spin to me.
