Underground Uranium
The UK Health Protection Agency estimates the typical Briton receives about 2,200 microsieverts of radiation per year frombackground radiation, or about 0.251 microsieverts per hour ‐‐ more than double the levels registered in Tokyo.
“Half of the average annual radiation to people in the UK comes from radon ‐‐ an invisible, colorless, radioactive gas present
in all soils,” John Harrison, deputy director of the agency's radiation center, said in an e‐mail. “It's a byproduct of the decayof uranium which is found in all soils around the world, and the amount that seeps out is dependent on the local geology.”
Cornwall, a popular tourist destination in southwest England , has four times the level of radon as other parts of the country,
he said.

London 0.251 uSv/h (typical )Natural Radiation
Natural radiation makes up about 85 percent of the global total, according to the World Nuclear Association. Manmade
contributors include medicine and buildings, as well as the nuclear industry, which accounts for 1 percent of the total, theassociation says. Foodstuffs also contain radiation, and a 135‐ gram (4.8‐ounce) bag of Brazil nuts has a dose of about 10
microsieverts, according to the U.K. agency.
ther activities that enhance naturally occurring radiation levels include mining, milling and processing of uranium ores andmineral sands, manufacturing and use of fertilizers and the burning of fossil fuels, according to a 2008 report by theInternational Atomic Energy Agency.
The highest level of background radiation is in the state of Kerala and city of Chennai in southern India, where people receive
average doses above 30 millisieverts per year, or 3.42 microsieverts an hour, according to the World Nuclear Association.
India has vast amounts of thorium in its soil. A millisievert is 1,000 microsieverts.
In Brazil and Sudan, exposure can reach 40 millisieverts a year or 4.57 microsieverts an hour, the Association says.
