Water is the most common chemical compound on the surface of the Earth, covering over two-thirds of the Earth's surface. People are also about two-thirds water. Water is a compound of hydrogen and oxygen.
According to a study in the Journal of Radioanalytical and Nuclear Chemistry, a group of scientists tested the amount of 239+240 Pu in soil levels in Nagasaki and the surrounding cities on the island. Their findings are shown in the Radiation Levels map shown above. The highest level of plutonium and radiation was found in the Nishiyama region, about 3 km east of the hypocenter. Likewise, there were amounts of plutonium found over 100 km away from the hypocenter in the Ohita region (Yoshida).
