Was Lot's wife zapped by cosmic rays?

From Wikipedia:

When the sins of the Sodomites and of the neighboring cities had called down the vengeance of God to punish and destroy them, two angels were sent to Sodom to forewarn Lot of the dreadful catastrophe about to happen. The angels took Lot, his wife, and his daughters by hand and drew them forcibly out of their house, saying, "Save yourselves with all haste. Look not behind you. Get as fast as you are able to the mountain, unless you be involved in the calamity of the city." Lot entreated the angels, who consented that he might retire to Zoar, which was one of the five doomed cities. His wife, looking back on Sodom, was turned into a pillar of salt.

Lot left Zoar and retired with his two daughters to a cave in an adjacent mountain. In Gen. 19:30-38, Lot's daughters incorrectly believed they were the only females to have survived the devastation. They assumed it was their responsibility to bear children and enable the continuation of the human race.

Sounds to me like another Noah story (according to the Qur'an Lot was a prophet) to me. And sounds like what might happen in 2012 - planet gets zapped by cosmic rays, smart folk like Lot are up a hill, in a cave... and his silly wife popped outside for a look and got fried.
