aThis confidence is also reflected in their development plans, particularly at the west coast facilities of Manzanillo and Lazaro Cardenas where additional container terminals are being built. 这信心在他们的发展计划也被反射,特别在Manzanillo和Lazaro Cardenas西海岸设施,另外的容器终端建造。[translate] ...
Plutonium and uranium contamination in soils from the former nuclearD ChildM Hotchkis
(Elements & Compounds) a highly toxic metallic transuranic element. It occurs in trace amounts in uranium ores and is produced in a nuclear reactor by neutron bombardment of uranium-238. The most stable and important isotope,plutonium-239, readily undergoes fission and is used as a reactor fuel...

Recent Examples on the Web An array of radioactive substances had been released during the disaster, including plutonium and uranium, but scientists were also on the lookout for harmful levels of radioactive cesium and iodine isotopes, which turned out to be the abundant and far-reaching contamina...
Berzelius 于1811年提议用现代拉丁语形成所有元素名称。由于一些最近发现的金属元素的名称已经是拉丁语形式(uranium, chromium, borium 等),因此保持了用 -ium 或-um 命名金属元素的模式(如 cadmium, lithium, plutonium 等; helium 是一个例外)。 广告
We present plutonium (Pu) and uranium (U) isotopic fingerprints (or signatures) in environmental samples collected at Bikar Atoll. Bikar is the second –most northern atoll of the Republic of the Marshall Islands, and therefore an important reference point to evaluate the extension of the regiona...
Plutonium (Pu), radioactive chemical element of the actinoid series of the periodic table, atomic number 94. It is the most important transuranium element because of its use as fuel in certain types of nuclear reactors and as an ingredient in nuclear wea

You see, the uranium or plutonium fission-bomb's been obsolete for over four hundred years. From Project Gutenberg Here was also a sacred cavern, styled by Strabo Plutonium, and Charonium; which sent up pestilential effluvia. From Project Gutenberg Rip went to it and examined the raw pluton...
