@petergleick No problem, eh. Canadians were key to developing the first nuclear weapons at Los Alamos and other secret sites of the #ManhattanProject , one of which was *in* #Canada (Chalk River, Ontario). torontosun.com/news/national/t

Btw, a Canadian is the *current* Director of Los Alamos National Laboratory.

torontosunThe life and tragic death of the Canadian who built The BombRichard Feynman called it “tickling the dragon’s tail.”

#Pioneering female #Chinese #American physicist Chien-Shiung Wu, who worked with Robert #Oppenheimer on the #ManhattanProject, was also the first to confirm #QuantumEntanglement – just 14 years after Albert #Einstein questioned the phenomenon. The largely forgotten achievement was included in a profile of Wu, one of the most influential experimental physicists of the 20th century, published in the December 2024 issue of Physics Today.

Wu is also believed to have been the only Chinese scientist involved in the Manhattan Project, the World War II initiative to develop an #AtomicBomb led by Oppenheimer, who affectionately referred to her as Jiejie, which means elder sister, the article said.

Wu’s experiment – detailed in a paper published in 1950 – was conducted before the #scientific community had fully grasped the significance of quantum entanglement, the article noted.

Today’s #TMYK (3/365) is also a #PSA: The guidelines for visiting the Trinity test site (location of the first nuclear weapon detonation) have been revised.

Visitors are now permitted only one day per year (used to be two) and the Alamogordo Caravan has been indefinitely canceled. 😭

There is good news, though. Signups are no longer required and it doesn’t seem there’s a cap on attendance.

I know where I plan to be on October 18!

The #US #DOE plans to build a 1 GW #solarfarm on a former top-secret #ManhattanProject #nuclear site in Washington State.
The DOE’s plan is to work with Hecate Energy to repurpose the Hanford Site, an 8,000-acre federal land site, as part of the #CleanupToCleanEnergy initiative launched in July 2023. The program aims to repurpose parts of DOE-owned lands – parts of which were previously used in the US’s nuclear weapons program – for #cleanenergy generation. electrek.co/2024/07/31/the-us-

#Navajo #uranium miners, people #downwind of atom bomb tests demand justice as Congress lets aid program lapse

WASHINGTON – "A federal program to compensate people exposed to fallout from U.S. nuclear testing expired June 10.

"The #Radiation Exposure Compensation Act has paid out $2.6 billion to over 41,000 people since 1992. In March, the U.S. Justice Department projected that another 1,070 claims would be approved by the end of September.

“'Why do we have to beg to pass #RECA?' said #MaggieBilliman, whose father, a #NavajoCodeTalker during World War II, died of stomach cancer she attributes to exposure to #fallout that affected their hometown in #Arizona. 'You don’t put a price tag on human life.'

"Starting with the #ManhattanProject’s Trinity test on July 16, 1945, weeks before bombs destroyed #Hiroshima and #Nagasaki, the U.S. government conducted 94 tests that produced radioactive mushroom clouds in remote areas of the West. Most were over #Nevada. One was over #NewMexico.

"People #downwind – including many in #Arizona – were exposed to dangerous #fallout, typically without warning.

"The Billimans’ hometown, #SawmillArizona, on #NavajoLand, is part of the large affected area where Congress made residents eligible for compensation.

"#Radioactive particles fell throughout Arizona, according to research from Princeton University’s Program on Science and Global Security. The state’s population grew from about half a million just before World War II to over 1.3 million in the early 1960s.

"Congress adopted RECA in 1992 to address claims from downwinders and uranium miners.

"The program offers an apology, and lump sum compensation ranging from $50,000 to $100,000 to those who developed certain illnesses linked with radiation exposure, and who either lived in the #FalloutZones or worked at #UraniumMines and #UraniumMills.

"The law came in response to lawsuits from uranium workers who accused the government of failing to warn them about radiation hazards.

From 1944 to 1986, nearly 30 million tons of uranium ore was extracted from Navajo lands. The Manhattan Project itself, led by physicist #RobertOppenheimer, was disbanded in 1947, two years after Japan surrendered to end World War II.

"An estimated 3,000 to 5,000 Navajo people worked in the mines. They and their families lived nearby.

“'The closer you live to mine waste, the higher your risk of chronic #metabolic disease,' said Chris Shuey, director of the Uranium Impact Assessment Program at the Southwest Research and Information Center, a nonprofit research and advocacy group. 'People who live in these communities next to these wastes, they’re exposed through all of the pathways: air, water, land.'

"Claims from Arizona, New Mexico, Utah and #Colorado account for $1.8 billion of the payouts under RECA.

"Most of the #NavajoNation was covered due to potential fallout. About one in seven approved claims – 5,480 through the end of 2023 – have come from #NativeAmericans, 86% of them Navajo, totalling $372.6 million.

"The Environmental Protection Agency counts 523 abandoned uranium mines on or near the Navajo reservation that spans Arizona, New Mexico and Utah, an area bigger than Massachusetts, New Hampshire and Vermont combined.

"The Senate voted 69-31 in March to extend the RECA filing period for five more years, with 46 Democrats and 20 Republicans in favor, along with Sen. #KrystenSinema of Arizona and two other independents. Sen. #MarkKelly, D-Ariz., also supported the bill.

The bill has stalled in the House, with no explanation from Speaker Mike Johnson or Majority Leader Steve Scalise, both Republicans from Louisiana.

"Their aides did not respond to multiple requests for comment."

💥🍄 Today, 79 years ago to the near minute, 5:29 a.m. MWT (12:29:21 BST) on July 16, 1945, #Trinity the code name of the first detonation of a #nuclear weapon, was conducted by the 🇺🇸 #Army as part of the #ManhattanProject.

The test was of an implosion-design #plutonium bomb, nicknamed "the gadget", of the same design as the Fat Man bomb later detonated over #Nagasaki, #Japan on August 9, 1945.
