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

Walmart has removed about 1,000 third-party items from its website in the wake of two mass shootings after determining the products violate company policy, a company spokesperson told CNN Tuesday.The retail giant regularly reviews its 75 million online offerings, looking for items that violate its ban on merchandise that glorifies violence, the company said. A recent review focused on gun-related items after 31 people were killed in mass shootings in El Paso, Texas, and Dayton, Ohio, earlier this month. The products were removed over the last week, the spokesperson said.The retailer has been facing pressure to remove firearms from its physical stores and criticized for selling pro-gun T-shirts on its e-commerce site.Last week, Walmart pulled displays of violent video games in its stores. But that policy change does not apply to the sale of controversial video games nor to the sale and display of firearms.At least 31 people were killed in separate shootings earlier this month in an El Paso Walmart and outside a strip of entertainment venues in Dayton. The Dayton shooter was killed by police within 30 seconds of opening fire.The 21-year-old suspect in the El Paso shooting surrendered to police on the day of the attack. He told police he was targeting Mexicans, according to an arrest affidavit.The El Paso shooting came a week after a disgruntled Walmart employee killed two co-workers and wounded an officer at a Southaven, Mississippi store. Walmart's CEO Doug McMillon said that the company will respond in a "thoughtful and deliberate" way to both shootings. 1592

When Beto O'Rourke opened the first Democratic debate by answering a question about tax rates in Spanish, he appeared to get some shade from Sen. Cory Booker.The New Jersey Democrat initially looked taken aback, impressed or jealous at the power move, which highlighted O'Rourke's ability to speak the language fluently and may have distracted from the fact that he could not or would not answer the specific question about whether he would support a 70% top tax rate.But maybe Booker was just frustrated that he didn't get to speak Spanish first. He pulled out his own language skills a short time later when the subject turned to immigration.One of the moderators, José Diaz-Balart, got in on the act as well, asking O'Rourke a question about the border in Spanish before repeating it in English.After the debate, Rep. Alexandria Ocasio-Cortez called the candidates' answers in Spanish "humorous, sometimes" but said they were "a good gesture to the fact that we are a diverse country.""I loved it, because I represent the Bronx. There was a lot of Spanglish in the building," the progressive congresswoman from New York told Stephen Colbert on "The Late Show." She also joked that because of the "content of the questions," she thought candidates may declare in Spanish, "I will not give you an answer to your question."If the importance of Latino voters to Democrats was in question (it wasn't), the translating Wednesday night was proof that Democrats want to appeal to Latino voters.According to census data collected in the American Community Survey, 21.3% of people in the United States speak a language other than English at home. Most of those, 13.2% of people in the United States, speak Spanish at home.It's larger percentages in some key Democratic states, such as California, which moved its primary to earlier in the process for 2020, and 28.7% of people speak Spanish at home.In Texas, home to both O'Rourke and former San Antonio Mayor Julián Castro, 29.5% of people speak Spanish at home.Castro, by the way, has admitted his Spanish skills are not top rate and he rarely spoke the language at home growing up even though his mother is a native speaker. At the end of the debate, he said one line: his name and that he's running for President. In English, he continued that that's the American dream since his grandmother emigrated from Mexico and now one of her grandsons is running for president and his twin brother is in Congress.O'Rourke learned the language growing up in El Paso, Texas, along the Mexico border. He and Castro tangled at the debate on immigration policy. Castro wants to decriminalize undocumented border crossings.Booker learned Spanish during a language immersion program in Ecuador. Bill de Blasio, the New York City mayor, did not speak Spanish at the debate, but he can.But neither O'Rourke's nor Booker's Spanish was flawless.When asked whether he supported a marginal tax rate of 70% on top earners making more than million a year, O'Rourke began his response in English."This economy has got to work for everyone and right now we know that it isn't, and it's going to take all of us coming together to make sure that it does," he said.He then switched to Spanish, saying, "We need to include each person in the success of this economy. But if we want to do that, we need to include each person in our democracy. Each voter, we need the representation, and each voice, we must listen to."He then reverted back to English for the rest of his remarks.O'Rourke made some notable errors, however. For example, he used masculine adjectives to describe "economy" and "democracy," which are feminine nouns in Spanish and he used the verb "to vote" before correcting himself and using the Spanish word for voter.When asked what he would do on Day One of his presidency if elected, Booker replied in Spanish, "The situation right now is unacceptable. This president has attacked, has demonized immigrants -- it's unacceptable and I will change this one."He then switched to English, saying, "On Day One, I will make sure that No. 1, we end the ICE policies and the customs and border policies that are violating the human rights. When people come to this country, they do not leave their human rights at the border."Booker's Spanish was also imperfect, as he said that he would change "this one" instead of "this."O'Rourke was also asked the Day One question, although in Spanish, by Diaz-Balart."We will treat each person with the respect and dignity that they deserve as humans," he said in Spanish.Marianne Williamson joked on Twitter that she needs to learn Spanish by Thursday night when the other 10 Democrats who have qualified for this first slate of debates square off.The-CNN-Wire? & ? 2019 Cable News Network, Inc., a Time Warner Company.
