GII PARTICIPATED IN RRU 2022

1. Bhabha Atomic research centre (BARC) has organised a two day theme meeting on Strategic Planning for Research Reactor Utilization (RRU-2022) during 6-7 May 2022 at Anushakti nagar Mumbai and Dharmendrakumar Chauhan, Nanddeep Keer and Dr. AVR Reddy of GII participated. A research contribution was poster presented (by Dharmendrakumar and Nanddeep) and an invited talk was delivered by Dr. Reddy.
2. GII has developed a quantitative method to estimate the low levels of cubic zirconia in diamond powder by using EDXRF and validated using Neutron Activation Analysis. It was poster presented in the conference. It was well received.
3. Dr. AVR Reddy was invited to give a talk on future work on Utilization of research reactors in coloured gemstones and diamonds, and he presented some of the earlier work and possible work that can be carried out using reactor neutrons.
4. One of the Trustees, Shri. Shripalkumar Desai spoke in a panel discussion on the status of Neutron irradiations for quality improvement.

 

 

 

 

 

 

Outcome: The results of estimation of CZ, obtained by EDXRF and NAA methods are in reasonable agreement, as the difference is insignificant. EDXRF method can be used to quantify CZ in the binary systems of diamond Powder and coating of Zirconia. Presentations by other scientists and discussions with them during these two days are very useful.


Gemmological Institute of India, Mumbai and National Gem Testing Center, China has entered an historical agreement between them for development and promotion of various technical and trade related aspects connected to Diamond Industry which will be of mutual benefit to both the countries.
