Prime Minister Ahbisit Vejjajiva said Tuesday that the controversial GT200 bomb detectors have been able to detect only four out of 20 explosives in scientific tests conducted by Science Ministry. "We won't buy any more GT200 bomb detectors as they do not work. It would be very risky to use them as, of the 20 tests conducted, results were achieved with only four, or just 25 per cent," the prime minister said.The Science Ministry conducted the tests on the devices over the weekend. The prime objective of the test was to ascertain the device's efficacy with results reported to the Cabinet meeting on Tuesday. The GT200 devices tested were those used by police and military units in the South.
Earlier, senior military ordnance officers and bomb-disposal personnel briefed the Cabinet and insisted that the GT200 was "sufficiently efficient". They said it had detected explosives, weapons and narcotics in 173 out of 236 incidences. "The success rate is higher than 80 per cent - beyond the minimum efficiency rate required," they said.
