Boron Rubber is effective for shielding thermal neutrons and to get over the restrictions on supply, BARC supported a project to develop neutron shielding material for the neutron beam guide and other instruments. The project was assigned to Prof. R.V. Mehta and Prof. R.V. Upadhyay and Dr. G.M. Sutaria of the Department of Physics, Bhavnagar University. Successful development led industrialist Deepak Doshi to start this venture.
