Primordial non-Gaussianity is a unique feature of the CMBR, precise measurement of which can constrain the existing inflationary models very stringently. I will discuss in this presentation the effects of a pre-inflationary radiation era on primordial non-Gaussianities. We found in our work that presence of such a radiation era enhances the fNL & τNL (parameters to determine non-gaussianity) by a considerable amount and yields large enough primordial non-Gaussianities that can be measured by future experiments. I will also discuss the methodology to calculate non-Gaussianities in such a scenario and the results thus obtained.
