...magnet affair goes beyond dollars and yuan. U.S. intelligence learned last year that a Chinese company had sold devices to Pakistan that are used to produce enriched uranium for nuclear warheads. The amount of money involved was small--less than $100,000--but the implications for the proliferation of nuclear weapons were very great. Although U.S. law called for sanctions against China, Secretary of State Warren Christopher ruled against them after receiving private pledges from his counterpart, Foreign Minister Qian Qichen. Qian told Christopher the top leaders had not known about the transaction and would make sure...
...waste to a medium-size city like New Orleans are two things. The first is an understanding of the technology involved, the easy availability of which has been demonstrated by innumerable high school science whiz kids. The second component is actual fissionable material--55 lbs. of enriched uranium, say, which would be enough to turn the heart of New Orleans into radioactive dust. With the increasing use of nuclear technology around the world and the destabilization of Russia, the once stringent global controls on uranium and plutonium are increasingly being subverted. U.S. intelligence officials admit that a terrorist would have...
Though NEST has yet to find a nuclear device, the team has unearthed conventional bombs. The only case involving nuclear material involved an employee at a Wilmington, North Carolina, nuclear fuel plant who stole a small amount of low-grade uranium and threatened to disperse it. The fbi quickly recovered the uranium, and NEST didn't have to be summoned...
Zircon dating, which calculates a fossil's age by measuring the relative amounts of uranium and lead within the crystals, had been whittling away at the Cambrian for some time. By 1990, for example, new dates obtained from early Cambrian sites around the world were telescoping the start of biology's Big Bang from 600 million years ago to less than 560 million years ago. Now, with information based on the lead content of zircons from Siberia, virtually everyone agrees that the Cambrian started almost exactly 543 million years ago and, even more startling, that...
...Nevertheless, I ask myself why Australia and New Zealand have not said a word about the Chinese nuclear tests that have continued to take place. Why don't they protest against the nuclear power plants still working in the former U.S.S.R.? Have the Australians forgotten that their country sells uranium to France? Chirac's government has decided to conduct the tests because of the French nuclear lobby, which represents companies that give thousands of people their jobs.
