International inter-comparison exercise on radon measuring devices completed at Mangalore University

This was the first such large-scale experiment organised in India involving several countries and it was conducted and organised in collaboration with the Radiological Physics and Advisory Division of Bhabha Atomic Research Centre (BARC)
The Centre for Advanced Research in Environmental Radioactivity (CARER), a national facility for radiation protection studies, at Mangalore University completed an international inter-comparison exercise on ‘radon measuring devices’ using the advanced calibration facility for radon measuring devices, recently.
This was the first such large-scale experiment organised in India involving several countries and it was conducted and organised in collaboration with the Radiological Physics and Advisory Division of Bhabha Atomic Research Centre (BARC), Mumbai. Ten laboratories from six countries — Japan, South Korea, China, Czech Republic, Vietnam and India — participated in these experiments, which were conducted over two months, according to the Head of CARER Karunakara Naregundi.
About 450 active and passive radon measuring devices were subjected to intercomparison measurements. These experiments involved accurately monitoring and controlling the environmental parameters and radon levels in the calibration facility and this was accomplished through innovative technology developed at the CARER. The intercomparison experiments are considered important to ensure the accuracy and precession of measuring devices/detectors, he said in a release.
Mr. Naregundi said that the state-of-the-art calibration facility was established at the CARER through financial support from the Board of Research in Nuclear Sciences (BARC).
“We are happy to inform that this is the largest walk-in type calibration facility in Asia (and the second largest in the world),” he added.

When fed into Latin, pusilla comes out denoting “very small”. The Baillon’s crake can be missed in the field, when it is at a distance, as the magnification of the human eye is woefully short of what it takes to pick up this tiny creature. The other factor is the Baillon’s crake’s predisposition to present less of itself: it moves about furtively and slides into the reeds at the slightest suspicion of being noticed. But if you are keen on observing the Baillon’s crake or the ruddy breasted crake in the field, in Chennai, this would be the best time to put in efforts towards that end. These birds live amidst reeds, the bulrushes, which are likely to lose their density now as they would shrivel and go brown, leaving wide gaps, thereby reducing the cover for these tiddly birds to stay inscrutable.
