Warm Up: NUCLEAR
CLUB: With your partner(s), talk about these nuclear (or
soon-to-be) powers. How dangerous is each one. Agree on a rank for them: 10 =
very dangerous; 1 = very safe. Change partners and tell each other your
rankings.

What exactly is a nuclear weapon?
There are different types of nuclear weapon – the atom bomb 原子彈, the hydrogen bomb 氫彈 and the neutron bomb 中子彈. All of them are designed to cause destruction 破壞 by releasing 釋放 huge amounts of energy at a specific time and place. The strength力量 of these weapons is measured測量 by comparing the force of the explosion 爆炸 to the weight重量 of TNT黃色炸藥 which would be needed to create the same effect影響力: for example, "25,000 tonnes".What exactly happens when a nuclear weapon explodes?
Generally, a nuclear explosion will release about 50% of its energy in the form of a blast炸毀. 30% of the force of the explosion will be in the form of heat and the remainder (20%) will be released as radiation. The blast will damage and destroy property, creating the problem of flying debris碎片, for example, bricks and broken glass.What happens after a nuclear explosion?
This depends on the amount of dust灰塵 and smoke released into the atmosphere大氣. Obviously, a nuclear explosion can cause immediate casualties傷亡– the blast, heat and radiation are deadly. In the longer term, radiation can continue to be dangerous when it falls back to us in the form of nuclear fallout 輻射落塵. It is alleged that after a nuclear war, there would be so much dust in the atmosphere that the sun would be blocked out and a nuclear winter would ensue接著發生, causing phenomenal damage to the planet's ecosystem生態系統 and jeopardizing危及 the survival存活 of all life forms, including humans.Who invented nuclear weapons?
In what ways are modern nuclear bombs different from past ones?
There are three types of nuclear weapon: "strategic" weapons which have a range of nearly 3,500 miles (5632 km), "intermediate" weapons which can hit targets between 600 (965 km) and 3,500 miles away, and "short-range" weapons which would be used for targets up to 620 miles (997 km) away.The neutron bomb, developed less than 30 years ago in the USA, is a special type of fission核裂變-fusion 核聚變 bomb and has been specifically enhanced提高 to injure or kill people with radiation, while leaving buildings largely intact完整無缺的.
