Researchers have measured the highest levels of ultraviolet radiation ever recorded on Earth. And it didn’t happen in Antarctica where there are holes in the ozone layer. The world record, a UV index of 43.3, occurred in South America at the top of Bolivia’s Licancabur volcano in 2003, Yahoo News reports. While a UV index of 12 is considered dangerous, numbers in the 30s or 40s are considered much worse. The find is described this week in Frontiers in Environmental Science.
