NEW DELHI (APP) In a rebuttal to recently retired Atomic Energy Commission Chief Anil Kakodkars claims about success of Indias 1998 thermo-nuclear explosions, a former senior nuclear scientist K Santhanam said Kakodkars was ignoring facts and called him a liar. In an interview to a news channel on Sunday, Kakodkar had claimed that yield of thermo-nuclear explosions was more than 45 kilo tons and India had credible thermo-nuclear bombs in its arsenal. Santhanam, a senor nuclear scientist from Defence Research and Development Organisation (DRDO) was responsible for monitoring the 1998 Pokhran nuclear explosions. Figures dont lie, but liars will figure. He chose to ignore facts for his own reasons, Santhanam said in an interview to an Indian news agency PTI on Monday in reply to Kakodkars claims. There are several inaccuracies in his (Kakodkars) statement. The DRDO was a major partner in the 1998 tests and not what Kakodkar has claimed...that we only provided logistical support. That is very far away from truth, Santhanam said. He (Kakodkar) is motivated by institutional loyalties, he said. We (DRDO scientists) were there as those responsible for the explosive trigger and measuring chain reaction in the core. We were responsible for full-fledged high-end explosive development and production without which the atom bomb is naked, Santhanam said. Santhanam said the Centre had entrusted DRDO with the responsibility of site instrumentation to measure the yield of the (nuclear) devise tested. These instruments were of international class and standards. There can be no two opinion on the quality of the instruments, he said, on Kakodkars remarks that these had not worked during the nuclear tests. Obviously the work done by DRDO is way beyond just logistics support, Santhanam added. When asked on Kakodkars assurances to the armed forces on the quality of the arsenal, the former DRDO scientist said assurances were alright, but at a deeper scientific level, one should not toy with scientific data. Santhanam said 11 years ago, in 1998, soon after the yield of the tests were collated, he had raised the issue. I think much more work needs to be done by the Trombay boys, the scientist said. Demanding an examination of the tests data by an independent panel of experts, who could later recommend future course to the government, the former DRDO scientists said most scientific nations would have done it, adding only in religion, no questions or doubts could be raised against preachings. In science, you question all the time till truth prevails, he added.
