Correction. A more current one. Wasn't the Godzilla premise something from nuclear testing?
I think you might be correct. The following taken from :

The "Second Atomic Bombing of Mankind"
Other events beyond the confines of the film industry also shaped the making of
Gojira and
Gojira no Gyakushu. In March of 1954, Japan suffered from another nuclear disaster, though far smaller in scale than the 1945 bombings of Hiroshima and Nagasaki. In the early morning hours on March 1, the twenty-three-man crew of the fishing ship,
Fukuryu Maru (Lucky Dragon) inadvertently sailed into the range of an American hydrogen bomb test site. The "Bravo" hydrogen bomb test at Bikini Atoll was about 85 miles away from the
Fukuryu Maru. The blast, equivalent to about twelve million tons of TNT, was 750 to 1,000 times more powerful than the atomic bomb dropped on Hiroshima. It was also twice as powerful as U.S. scientists had led the world to expect. “The sky in the west suddenly lit up and the sea became brighter than day,”
Fukuryu Maru crew member Yoshio Misaki recalled. “We watched the dazzling light, which felt heavy. Seven or eight minutes later there was a terrific sound; like an avalanche. Then a visible multi-colored ball of fire appeared on the horizon.” For several hours after the test, white ash began falling onto the decks of the
Fukuryu Maru and crew members began collecting bags of it as souvenirs. Before nightfall that day, everyone on board the fishing boat was ill.
The crew of the
Fukuryu Maru is believed to be among the first civilians ever confirmed to have been accidentally exposed to fallout from a nuclear weapon. All twenty-three people on board the boat were hospitalized after returning to Japan, and one of them, radio operator Aikichi Kuboyama, died seven months later of kidney failure reported to be caused by radiation (although it was later revealed that he had in fact died of an unrelated case of hepatitis). Several hundred inhabitants of the Marshall Islands in the Pacific, as well as nearly thirty U.S. personnel connected with the tests, also became ill from the nuclear fallout. The
Fukuryu Maru incident triggered a crisis in relations between the United States and Japan, in part because of Washington’s attempted to maintain secrecy over its nuclear tests. The debate centered on whether the ship’s crew was at fault or whether the radius affected by the test far exceeded the estimated range and had in fact caught the ship in supposedly safe waters. The incident was dubbed “The Second Atomic Bombing of Mankind” by the Japanese press. Eventually the U.S. government issued an apology and paid $2 million in compensation to the Japanese Government, but the incident continued to generate controversy. Fearing nuclear contamination, the Japanese destroyed tons of fish caught in the affected area of the Pacific. As a nation, the Japanese avoided fish for months after the
Fukuryu Maru incident, resulting in millions of dollars in losses for the country's fishing industry and related businesses.
It was this situation that inspired the Toho Company to make its first movie monster a radiation-mutated sea creature terrorizing mankind, and planted the seed in Tanaka’s mind as to how to replace his aborted war film,
In The Shadow of Glory. Tanaka had impressed Mori with his idea to replace
In The Shadow of Glory with his idea about “a monster that invades Tokyo the way King Kong attacked New York,” and without Mori’s support it is doubtful that the project would have ever have gotten off the ground. But Mori liked the project and the go ahead was given. Now the task of producing Tanaka's "radiation monster" film (which would be
Gojira) was in the hands of director Ishiro Honda and special effects supervisor Eiji Tsuburaya.
