【貧鈾彈】世界最強滅絕性穿甲彈，3000米內一砲連穿兩輛T72，影響人類環境長達45億年，為何沒有被禁止

貧鈾彈是指以含有鈾238的硬質合金為主要原料製成的砲彈和槍彈。其作用原理跟普通穿甲彈相同，是利用貧鈾合金的高硬度、高比重和高熔點依靠動能來穿透目標，其多用來毀傷坦克等裝甲目標。
其主要成分是鈾238，具有一定的放射性，但由於其半衰期較長（4.468×10^9年），所以其放射性相對弱於鈾的其他同位素。美國原子能標準委員會（NRC）將鈾235低於0.711%的鈾定為貧鈾，美國國防部標準為鈾235含量在0.3%以下，而實際使用的標準是0.2%。 1943年8月，美國曼哈頓計劃的研究小組曾經給五角大樓寫過一個報告裡面提及了“使用貧鈾彈及鈾238廢料製成的彈藥，能沾染敵方土地，削弱敵方的戰爭潛能”。
Depleted uranium bullets refer to shells and bullets made of hard alloy containing uranium 238 as the main raw material. Its principle of action is the same as that of ordinary armor-piercing projectiles. It uses the high hardness, high specific gravity and high melting point of depleted uranium alloys to penetrate the target by relying on kinetic energy. It is mostly used to damage armored targets such as tanks.
Its main component is uranium 238, which is radioactive to a certain extent, but due to its long half-life (4.468×10^9 years), its radioactivity is relatively weaker than other isotopes of uranium. The U.S. Atomic Energy Standards Commission (NRC) defines uranium with less than 0.711% uranium-235 as depleted uranium, and the U.S. Department of Defense standard for uranium-235 content is less than 0.3%, while the actual standard is 0.2%. In August 1943, the research team of the Manhattan Project in the United States wrote a report to the Pentagon, which mentioned that "munitions made from depleted uranium bombs and uranium-238 waste can contaminate the enemy's land and weaken the enemy's war potential."
