A study shows that the US nuclear test had effects as far away as Canada and Mexico.

A recent study found that the US military's first nuclear bomb, which was detonated in New Mexico without being seen, did a lot of damage and sent toxic particles as far as Canada and Mexico. The study, which came out last week before it was sent to a peer-reviewed magazine for review, shows that the plume and its rain went farther than anyone working on the Manhattan Project in 1945 thought they would. The study's writers used cutting-edge modelling software and newly found weather data from the past. They said that the nuclear fallout from the Trinity test reached 46 states, Canada, and Mexico within 10 days of the explosion. The study's lead author, Sébastien Philippe, a researcher and fellow in Princeton University's Science and Global Security Programme, said, "It's a big finding, but no one should be surprised by it."

The test, which took place in New Mexico on July 16, 1945, made a lot of people sick and polluted a lot of land. The Programme on Science and Global Security (SGS) at Princeton University was in charge of the study. Researchers used "high-resolution, reanalyzed historical weather fields, US government data, and complex atmospheric models" to figure out where radioactive fallout went in the days after the first nuclear test. Research shows that 10 days after the nuclear test, a mushroom cloud with a height of 50,000 to 70,000 feet appeared and sent toxic particles as far as Canada and Mexico. The study says that on July 20, 1945, plutonium from the Trinity test site made its way to Crawford Lake in Canada on the wind. Between 1944 and 1945, the number of babies who died in New Mexico rose by 56% because of the Trinity Test.

The Trinity test and the other nuclear tests that came after it were part of the secret Manhattan programme. This was an effort by the US government to make the atomic bomb. After Trinity, there were 93 more air tests in Nevada. During these tests, radioactive smoke clouds spread nuclear fallout across the United States. The story says that the US government has also done 45 "air blast tests," in which nuclear bombs were set off on rockets in the high atmosphere of the Earth. In a shocking fact, the US government is said to have made people stand under one of these air blasts to study what would happen to their health if they were directly exposed to dangerous nuclear radiation. From 1945 to 1962, which is the time frame that the experts looked at, the US military did 101 nuclear tests. A big part of the US's nuclear arsenal is the many hidden nuclear bombs that were not part of the study.

The Libertarian Institute said that between 1951 and 1998, the United States blew up more than 800 nuclear weapons that were hidden underground. Philippe said, "Our results show that Trinity's fallout has a big effect on the overall density of deposits in countries that border the U.S., and in New Mexico in particular." "It's hard to figure out how much of the Trinity fallout is still at the original sites across the country," said Susan Alzner, who helped write the study. Nearly half a million people lived within 150 miles of where the Trinity blast happened. Some families living 12 miles away or more. Still, the New York Times said that no people were told about the test ahead of time, and they were not moved before or after the test. The US government has told people in the area that the blast was caused by an accident at a munitions store nearby. The victims got sick, and some of them got cancer. They have been paying for it ever since. A US think tank called Responsible Statecraft said, "Once the original shock wore off, people went back to their normal lives.

They drank water from cisterns that were full of nuclear waste, ate beef from cows that had been eating the dust for weeks, and breathed air that was full of tiny plutonium particles. Only later would people understand what it really meant. The study also shows that there are important radioactive sources in Nevada, Utah, Wyoming, Colorado, Arizona, Idaho, and dozens of nationally recognised tribe areas. On August 9, 1945, the US dropped on Nagasaki a copy of the plutonium-239 detonation device that had been tried at Trinity.
