Uranium ore stored at the Grand Canyon National Park museum may have exposed visitors and workers to elevated levels of radiation, according to the park's safety, health and wellness manager.Elston Stephenson told CNN that he began asking officials from the National Park Service and Department of the Interior last summer to warn workers and tourists they had possibly been exposed to unsafe levels of radiation. After his requests were ignored, he said he sent an email to all park staff at the Grand Canyon on February 4."If you were in the Museum Collections Building (bldg 2C) between the year 2000 and June 18, 2018, you were 'exposed' to uranium by OSHA's definition," said the email, which Stephenson provided to CNN."Please understand, this doesn't mean that you're somehow contaminated, or that you are going to have health issues. It merely means essentially that there was uranium on the site and you were in its presence. ... And by law we are supposed to tell you."The National Park Service is investigating what happened and working with the Occupational Safety and Health Administration and the Arizona Department of Health Services, according to the Department of the Interior, which oversees the park service."Uranium naturally occurs in the rocks of Grand Canyon National Park. A recent survey of the Grand Canyon National Park's museum collection facility found radiation levels at 'background' levels -- the amount always present in the environment -- and below levels of concern for public health and safety. There is no current risk to the public or Park employees," the department said in a statement provided to CNN. The National Park Service also said there is "no current risk" to the public or park employees."The museum collection facility is open and employee work routines have continued as normal," Emily Davis, spokeswoman for the Grand Canyon National Park, said in a statement. "The NPS takes public and employee safety and the response to allegations seriously. We will share additional information about this matter as the investigation continues."Stephenson told CNN that in early June he found out about three 5-gallon buckets of uranium ore that had been stored next to a taxidermy exhibit at the park's museum for nearly two decades. He said he immediately contacted a park service radiation specialist to report the danger.According to a report from a park service radiation safety officer who responded to Stephenson's request on June 14, 2018, testing results were positive for radioactivity above background levels near the buckets, but elsewhere the radiation levels were not elevated.Still, according to the report, the park service decided to remove the buckets on June 18 and dispose of the contents in the nearby Lost Orphan uranium mine, where the ore had come from.Stephenson told CNN that park service workers were inadequately prepared to handle the radioactive material, moving the buckets wearing gardening gloves purchased at a general store, and using mop handles to lift the buckets into pickups for transport.Stephenson said that after trying and failing for months to get National Park Service officials to inform employees and the public about the possible uranium exposure, he filed a complaint with OSHA in November.The next day, Stephenson said, OSHA sent inspectors in protective suits to check the museum and found that park service workers brought the buckets back to the park facility after dumping the uranium ore."OSHA has an open investigation on the issue that was initiated on November 28," OSHA spokesman Leo Kay said in statement to CNN, declining to comment further on an active investigation.Staff for US Rep. Tom O'Halleran, D-Arizona, met with Stephenson in December, according to Cody Uhing, the congressman's communications director."We flagged this to the Natural Resources Committee, which is responsible for oversight for that area. They and we have requested the Department of the Interior's Office of the Inspector General to look into it and provide us with a report," Uhing said.The Department of the Interior's Office of the Inspector General confirmed Tuesday that it had received a letter from O'Halleran and that it would review it.Anna Erickson, associate professor of nuclear and radiological engineering at Georgia Tech, said the uranium exposure at the museum is unlikely to have been hazardous to visitors."Uranium ore contains natural (unenriched) uranium which emits relatively low amounts of radiation," Erickson said. "Given the extremely low reading (zero above background) 5 feet away from the bucket, I'm skeptical there could be any health hazards associated with visiting the exhibit."Stephenson told CNN that tours of schoolchildren often walked by the buckets at the museum, but his larger concern was for park employees and high school interns working near the uranium every day."A safe workplace really is a human right," he said. 4984

WASHINGTON — The National Transportation Safety Board says the driver of a Tesla SUV who died in a Silicon Valley crash two years ago was playing a video game on his smartphone at the time. Chairman Robert Sumwalt said at the start of a hearing Tuesday that partially automated driving systems like Tesla's Autopilot cannot drive themselves. Yet he says drivers continue to use them without paying attention. He says the board made recommendations to six automakers to stop the problem and only Tesla has failed to respond. The board will determine a cause of the crash at the hearing and make recommendations to prevent it from happening again.According to 670

USA Swimming sent a letter to the United States Olympic & Paralympic Committee formally asking Team USA to request that this summer's Olympic Games be postponed due to the spread of coronavirus. Meanwhile, Japan and the International Olympic Committee pressed forward with the buildup to the Olympics. On Friday, the Olympic Flame landed in Japan as the 2020 torch relay began. Whether coronavirus still poses a major threat in July and August is still debatable, many athletes would have been set to undergo Olympic qualifying in the coming weeks. Nearly 43% of all spots are still up for grabs in this summer's Olympics. USA Swimming CEO Tim Hinchey said it is time for the IOC to put forward a concrete timeframe. "Everyone has experienced unimaginable disruptions, mere months before the Olympic Games, which calls into question the authenticity of a level playing field for all," Hinchey said. "Our athletes are under tremendous pressure, stress and anxiety, and their mental health and wellness should be among the highest priorities." 1057

US tennis star Mike Bryan has been fined ,000 for pretending to shoot an on-court line judge with his racket at the US Open Sunday.The doubles player was initially handed a code violation for unsportsmanlike conduct by chair umpire Mariana Alves during his second-round win with brother Bob against Federico Delbonis and Roberto Carballés Baena.Bryan had successfully challenged the line judge's decision after replays on the big screen showed the ball had landed narrowly behind the baseline.After the call was corrected, Bryan mimicked a rifle with his racket and aimed it at the line judge in question.'Meant to be playful'The incident came on the same day that a series of new firearm laws went into effect in Texas just hours after a shooting left seven people dead in the western part of the state.The new gun laws will further loosen gun restrictions in a state that's had four of the 10 deadliest mass shootings in modern US history, including the El Paso shooting last month, when a gunman stormed a Walmart and killed 22 people.The six-time US Open doubles champion later apologized for his actions, saying it was an honest mistake."We won the point and the gesture was meant to be playful," Bryan said in a statement given to the 1255

WASHINGTON, D.C. – President Donald Trump announced several new actions on Wednesday that his administration is taking to combat the ongoing coronavirus crisis. One of the big updates that Trump announced during his White House press briefing was that the Department of Housing and Urban Development (HUD) will be suspending all foreclosures and evictions until the end of April. HUD's move is meant to bring relief to renters and homeowners who will lose income as the country practices social distancing due to the COVID-19 outbreak.Trump also said that he is invoking the Defense Production Act to expand the U.S. response to the outbreak. The federal provision, “confers upon the president a broad set of authorities to influence domestic industry in the interest of national defense,” according to the 819
