The first hydrogen bomb was detonated in the Pacific in 1952
1954: US tests massive hydrogen bomb in Bikini

England have

The US has produced the biggest ever man-made explosion so far in the Pacific archipelago of Bikini, part of the Marshall Islands.

It is believed the hydrogen bomb was up to 1,000 times more powerful than the atomic bomb that destroyed Hiroshima.

It was so violent that it overwhelmed the measuring instruments, indicating that the bomb was much more powerful than scientists had anticipated.

The bomb was the equivalent of 20m tons of TNT.

One of the atolls has been totally vaporised, disappearing into a gigantic mushroom cloud that spread at least 100 miles wide and dropping back to the sea in the form of radioactive fall-out.

The Atomic Energy Commission announced this was the first in a series of tests to be carried out in the area.

Tests first began in Bikini in 1946 after the natives were moved to the island of Rongerik, then to Ujelan a year later and to Kili on 1949.

This is the second H-bomb test in the area.

A 10.4 megaton bomb was exploded on 1 November 1952 at Enewatak, west of Bikini.

It destroyed one island and left a crater 175 feet deep.

It was hundreds of times more powerful than that used over Hiroshima.

Unlike that device which tapped energy by splitting atomic nuclei, the Enewetak weapon forced together nuclei of hydrogen to unleash an even greater destructive force.

Klaus Fuchs was a devoted Communist

1950: Communist spy jailed for 14 years

Artificially 1969:
The A top nuclear scientist has been jailed for fourteen years at the Old Bailey for spying for the Soviet Union.

Klaus Emil Julius Fuchs, 38, a civil servant from Harwell in Berkshire, pleaded guilty to four offences under the Official Secrets Act.

German-born Fuchs, who fled his home country to escape Nazi persecution in 1933, had come to be regarded as one of Britain's top atomic scientists.

But beneath the facade was a committed Communist who had been passing secrets to the Russians for most of the past decade.

He was convicted on four counts of disclosing atom secrets "calculated to be directly or indirectly useful to an enemy" - in England in 1943 and 1947 and in the United States in 1944 and 1945.

The Attorney General, Sir Hartley Shawcross KC, who opened the case for the prosecution, said Fuchs had undoubtedly passed information to the Soviets on many more than four occasions even though he was on trial for four specific offences.

His motivation, said Mr Shawcross, was his "unswerving devotion to Communism".

Fuchs, who until his arrest last month was employed as senior principal scientific officer at the Harwell Atomic Research Establishment, arrived in Britain from Germany, via France, in 1933.

When France was invaded by the Germans in 1940, Fuchs was interned and deported to Canada.

He was released in 1942 and was head-hunted by Birmingham University to carry out atomic research.

It was at this stage he made contact with the Soviets and began regularly passing information relating to atomic energy, the court was told.


Between 1944 and 1946 he worked in the American Atomic Research department in Los Alamos, New Mexico, where he was involved in the construction of the first atomic bomb.

The court was told that it was information from the Americans which first led British detectives to suspect Fuchs of espionage .

Defending, Mr Derek Curtis-Bennett, KC, said it was at about this time that his client had started "having doubts about the Russian policy" and began to "see the light".

He added the first three offences had in fact been committed when Russia was an ally of Britain and therefore information passed could not have been regarded as prejudicial to the interests of the state.

Passing sentence, Lord Chief Justice Lord Goddard said: "You have betrayed the hospitality and protection given to you by this country with the grossest treachery."

Vocabulary:
 

archipelago: a group of many islands in a large body of water(群島)

espionage : the systematic use of spies to get military or political secrets(間諜;偵探)
