Nuclear Hydrology Laboratory
The Nuclear Hydrology Laboratory was established in the year 1993 under the UNDP assisted project “Developing Capabilities for Hydrological Studies”. The laboratory is well equipped with the instruments for measurement of stable as well as radioisotopes.
In an international comparison exercise organized by International Atomic Energy Agency, Vienna during the year 2000 for measurement of Environmental Tritium, the laboratory results were excellent amongst 102 participated laboratories.
Performance of Isotope Laboratory was again found excellent amongst >175 laboratories participated in “Inter laboratory comparison exercise for δ2H and δ18O analysis of water samples”,an international comparison exercise organized by International Atomic Energy Agency, Vienna during the year 2011 & 2016.
