关于铀、钚和铀核裂变产物的若干问题——兼谈2011年福岛核事故泄露的放射性物质

A Number of Issues about Nuclear Fission Products of Uranium, Plutonium and Uranium——Co-discussion of the Radioactive Substance in the Nuclear Leaking Accident in Fukushima in 2011

文章以日本福岛核电站7级核事故两周年为契机和切入口,主要涉及:常用的核裂变材料———铀;铀原子核裂变("两分裂")产物;另一种核裂变材料———钚;福岛核电站核事故后外泄的放射性物质等。文章还以福岛核电站7级核事故为例,立足于传播基础核知识、核能知识及有关新信息,文章以铀、钚及其裂变为中心,对核事故与核污染等做了些介绍、说明,意在让更多的人科学地认知相关事件与现象。

The article starts from the 2nd anniversary of the 7th level nuclear leaking accident in Fukushima.It covers nuclear uranium,a product of uranium nuclear fission（＂splitting＂） and plutonium-another nuclear fissile material and other radioactive substances given off from Japan＇s Fukushima nuclear power plant.This paper takes the example of the 7th level nuclear accident of the Fukushima nuclear power plant,and bases on the spread of basic nuclear knowledge,nuclear knowledge and new information.It centers around uranium,plutonium and its fission,and illustrates the nuclear accident and nuclear pollution,which is intended to allow more people to understand the events and phenomena scientifically and cognitively.
