ヨルダン：ディーシーの水は放射能汚染されていない
ヨルダン政府は、南部の大規模な地下水源（化石水？）をくみ上げ、飲用水として活用するプロジェクトを推進している。ところが、Wikipediaなどでは放射能を帯びていると指摘されており、それについて「地下にある状態ではラドンを含んでいるが、地上にくみ上げたときに気化して水からは無くなるので、問題ない」と説明している。
'Disi water uncontaminated'

AMMAN - The water of the Disi basin is not polluted and is potable, Jordanian Geologists Association President Bahjat Al Adwan said on Tuesday, dismissing a report on a news website claiming otherwise.
Adwan, speaking to The Jordan Times over the phone, denied claims that the basin water is radioactively contaminated.
Adwan said the water does have radon, but the gas disappears as soon as the water is pumped from the underground and reaches the surface.
"As soon as the water is pumped out, a chemical reaction occurs between the air and the gas, causing it to fade away," said Adwan, adding that water is safe for human consumption and that such reports are damaging.
Any deep-seated underground water has some sort of radioactivity, said Elias Salameh, a University of Jordan professor of hydrogeology and hydrochemistry.
Once the water is pumped out, it is checked for radioactivity, he said, noting that if any high concentration is found, the water is treated.
University of Jordan mineralogy Professor Hani Khouri confirmed that the water is uncontaminated and that radioactivity is a natural occurrence.
"In the case of any remaining radiation, it is easily removed through aeration and filtration processes," Khouri said.
The Disi water conveyance project, slated for completion in 2013, entails the construction of a pipeline to convey water from the ancient Disi aquifer in southern Jordan to Amman.
The project is expected to provide the capital with 110 million cubic metres of water through the pipeline that will pass through several water stations in Maan, Tafileh, Karak and Madaba.
Ten per cent of the Disi basin is in the south of Jordan and 90 per cent in Saudi Arabia, which uses it for agricultural and drinking purposes.
