1950's rain drops in kerala when dried showed white powder from hydrogen bomb blasts; nobody knew it will cause cancer [From a high of 65,000 active weapons in 1985, there are now about 8,000 active nuclear warheads and about 23,300 total nuclear warheads in the world in 2009]

THERE WAS OPEN COMPETITION BETWEEN USA AND SOVIET RUSSIA TO BLAST NUCLEAR WEAPONS;ATOM BOMBS ;HYDROGEN BOMB ;NEUTRON BOMBS - BIGGER AND STRONGER IN OPEN AIR FOR A LONG TIME FROM 1950 TO 1970 CAUSING ATMOSPHERIC POLLUTION WITH DEADLY RADIATION CLOUDS WHICH TRAVELLED THOUSANDS OF KILOMETERS HIGH IN STRATOSPHERE AND TO SPREAD THE RADIATION .NOBODY KNEW IN THE BEGINNING THAT RADIATION WILL CAUSE CANCER

WHITE POWDER USED TO BE SEEN IN 1950'S WHEN RAIN DROPS DRIED ;DURING MONSOON RAINS ,FROM SUCH RADATION POLLUTED CLOUDS

NOW CANCER HAS INCREASED AS A RESULT


Bikini island open atomic blasts by usa:-
The B-29 designated to drop Able was named "Dave's Dream," and on July 1, 1946, at about 8:45 AM, the first peacetime detonation of a nuclear ordnance occurred. In the coming years, some twenty additional bomb tests would be conducted before the United States government officially returned control of the islands over to their natives in 1969. The largest test, Castle Bravo, also proved to be a large radiation fallout disaster: ashes from the explosion flew miles into inhabited islands, putting nuclear fallout into the public minds of many.
The Aftermath
Shortly after the announcement that the islands were safe, a group of the native people left their makeshift home to return to Bikini. Upon arriving at the island, the natives found rusting equipment, concrete, and unused naval machinery instead of palm trees and coral reefs. Nonetheless, a few determined men and women set about rebuilding the islands. They successfully cleared away tons of leftover eyesores and began life anew, but were evacuated ten years later after developing radiation poisoning from Cesium-137, (some sources also state Strontium-90), a remnant of the radioactive fallout. As of 2009, the islands remain uninhabitable
