Wake up call or tempest in teapot
the primary heat transport loop of the nuclear reactor and loaded it into a drink dispenser in the employee canteen.
Eight workers drank some of the contaminated water. He points out jeremy scott wings that in the 1980s a vast area in the BARC campus got contaminated by radioactive effluents accidentally discharged from the plutonium plant and the soil had to be decontaminated.
In another incident, scrap metal in Mumbai's adidas wings "chor" (thieves) bazaar that was found radioactive was traced to the plutonium plant at BARC. A worker had sold some discarded plant parts. Parthasarathy, former secretary of the Atomic Energy Regulatory Board told IANS he is aware of a case when a worker actually drank some heavy water containing tritium, in the hope he would isabel marant sale get a few days off from work. "He was crazy."
Tritium is the radioactive isotope of hydrogen but the beta radiation emitted by it is of such low energy it cannot even penetrate the human skin. In other words tritium can cause harm only if it enters the body through food or water but its intake must be in large amounts to pose a significant health risk.
Though tritium has a long a radiological half-life (12.3 years) its jeremy scott adidas biological half life -- time it takes for half of the activity to adidas jeremy scott be physically removed from the body air max shoes -- is about 10 days which can be shortened to 2-3 days by drinking a lot of fluid.
Some tritium is naturally formed in the upper atmosphere by cosmic rays. The air also contains tritium left behind air jordans for sale by atmospheric weapons testing between 1954 and 1962. But most tritium in the environment today is discharged from Kaiga-type adidas originals jeremy scott reactors that use heavy water as moderator and isabel marant coolant.
Heavy water is chemically the same as regular (light) water, but with the two hydrogen atoms replaced with atoms of deuterium -- another mulberry bags outlet isotope of hydrogen.
During reactor operation, deuterium jordan for sale in heavy water is activated by fission neutrons to form tritium. It is an important material in nuclear weapon design for boosted fission weapons and also has civilian applications - for instance in watch dials that glow in the dark. If not recovered from the used heavy water, tritium is discharged from reactors in its elemental form as a gas through stacks or in the form of tritiated water into the lakes celine bags online isabel marant sneakers and the sea.
Irrespective of how tritium entered the Kaiga water cooler, the incident highlights the need for vigilance in nuclear plants, says Parthasarathy. "Traditionally we have been thinking of securing nuclear plants from earthquakes and tsunami but the Kaiga incident has added another dimension to it."
A retired director of mulberry handbags uk one of the nuclear stations, who does not want to be named, agrees.
"Security today means checking handbags and inspecting vehicles and vigilance is all about who takes bribe," he said. "Our security at this level is good but nike air max is unprepared to deal with potential threats from scientific staff." A nuclear reactor has several hotspots and tampering with any of these can cause a radioactive accident a lot more severe than the trivial incident at the water cooler, he said.
"Scrutiny celine mini bag of staff is totally missing in our power stations," he warned, adding that this calls for urgent attention considering that hundreds of new jobs will be created in the coming years with the projected expansion of India's nuclear programme.
"At present our plants are guarded by persons supplied by the Central Industrial Security Force (CISF) and they take orders from their own boss in Hyderabad or Delhi and not from the station director," he said. "The nuclear plants should have their own security staff with some training in reactor operation."
