Threats from the past

at least 11,000 us citizens died from cancer after being exposed to radioactive fallout from nuclear testing done during the Cold War. This was revealed in the report of a recent study conducted by the us Department of Health and Human Services (dhhs). The report further mentions that virtually every …

Laxity to be probed

taking into account charges levelled against the French government, alleging that it had downplayed risks to public health after the 1986 Chernobyl nuclear disaster, a judge has ordered that official documents be seized as part of a probe to establish the truth. The accusations have been made by the Commission …

N plants face closure

taking a cue from Sweden and Germany, Belgium is going ahead with its plan to phase out the country's nuclear reactors by 2025. Belgian Prime Minister Guy Verhofstadt recently said that his cabinet would ask parliament to pass a controversial bill to this effect. "We are going to proceed with …

N plant weeded out

ON FEBRUARY 2, 2002, the Atomic Energy Regulatory Board (AERB) may have finally brought the curtain down on India's first pressurised heavy water nuclear reactor - Rajasthan Atomic Power Station's unit-I (RAPS-I). India's nodal regulatory body for its civil nuclear establishment took the decision to decommission RAPS-I by April 30, …

Data play

The Bhaba Atomic Research Centre (barc), Mumbai, used "wrong' data and "unacceptable' methods of analysis to arrive at erroneous results that were published in several journals and world conferences between 1989 and 1991. This has been stated in a paper published in the Indian scientific journal Current Science. The paper …

Super heavy elements

the first attempt to prepare a transuranic element (which is heavier than uranium) was made in 1934 in Rome, where a team of Italian physicists headed by the legendary Enrico Fermi bombarded uranium nuclei with free neutrons. The first such element produced was neptunium with an atomic number 93. (Atomic …

Thailand

Around 100 villagers in Thailand protested on August 27 against a decision of the House budget scrutiny panel to approve funds for a nuclear research project at Ongkharak district in Nakhon Nayok. The villagers also demanded that the government must revoke the contract which was signed between Atomic Energy for …

Fusion reactor

Scientists at the Lawrence Livermore Laboratory have made a thermonuclear fusion reactor that, they claim, can fit on a laboratory bench. The reactor consists of a femtosecond laser (femtosecond is a million-billionth of a second) that hits laser pulses at clusters of deuterium atoms. The cluster explodes because of the …

The aftermath

the testing of five nuclear devices on May 11 and May 13, 1998 - including a thermonuclear-boosted fusion bomb, a lighter but more powerful fission bomb of the type tested in May 1974, a low-yield nuclear device and two sub-critical tests - thrilled scientists and people alike. Heads of state …

Inside view

it is something that has always tempted physicists. What does the inside of a atomic bomb looks like a microsecond after it detonates? In fact, scientists at the Los Alamos National Laboratory, usa , stayed up nights thinking about it, and a group of them recently demonstrated a clever new …

Nuclear capacity

ACCORDING to a study published by the Institute for Defence Studies and Analysis (IDSA), New Delhi, India will have the capacity to produce up to 50 nuclear weapons by the year 2000. The study says that going at the present rate of plutonium (which is a fuel used in producing …

Target: neutrino mass

several experiments are being conducted by researchers to measure the mass of neutrinos

Nuke deal

with a view to curbing the spread of Russian nuclear technology to other countries, the us department of energy will be funding the development of a new nuclear reactor design at the Kurchatov Institute in Moscow. The us will provide a new technology that makes use of radioactive thorium instead …

Trail of danger

THE French are quitting the Mururoa and Fangataufa atolls in the South Pacific, but are leaving in their wake fears of possible nuclear contamination. After conducting at least 123 nuclear tests beneath the Mururoa rocks and eight under Fangataufa between 1975 and 1996, France finally announced to the world that …

Any after effects?

the Pacific atolls of Mururoa and Fantagaufa will once again become beehives of activity. This time, however, instead of the booming nuclear explosions, there will be scientific work carried out to study the radiological effects of the nuclear tests. International scientists will be collecting all types of terrestrial and marine …

In Focus

The world may finally bid good bye to all nuclear test explosions. But there are a few stumbling blocks to be crossed before leaders from 93 countries give their final approval to the Comprehensive Test Ban Treaty (CTBT), by the end of the current session of the Conference of Disarmament, …

Nukes no more

THE South Pacific region will now be out of bounds for countries wanting to conduct nuclear tests. At long last France, the UK and the us (with Russia and China) finally affixed their signatures, on March 25, to the I I -year old Treaty of Rarotongo, which seeks to ban …

PELINDABA ACCORD

The conflict-ridden continent can still hope for peace. In a concerted effort to ban nuclear weapons in the continent, government leaders and ministers from all 53 African countries are set to sign a treaty to this effect in this month. The treaty, drafted with the support of United Nations, aims …

In Focus

France, which had raised the ire of many nations by going ahead with its underground nuclear testing programme from September last, may have to face some more music. Reportedly, the atomic tests were not all that safe as the French had vociferously proclaimed. Radioactive elements -iodine 131, cesium and tritium …

All for the nuke

EVEN before the dust has settled after France's latest "nuclear outrage", the country is about to get embroiled in yet another nuke controversy. The French Academy of Sciences will officially publish a report later this month that will advise the French government to ignore an international recommendation to tighten radiation …
