Analogous to the well-known proton charge radius puzzle, a similar puzzleexists for the deuteron charge radius, $r_{d}$. There are discrepanciesobserved in the results of $r_{d}$, measured from electron-deuteron ($e-d$)scattering experiments, as well as from atomic spectroscopy. In order to helpresolve the charge radius puzzle of the deuteron, the PRad collaboration atJefferson Lab has proposed an experiment for measuring $r_{d}$, named DRad.This experiment is designed to measure the unpolarized elastic $e-d$ scatteringcross section in a low-$Q^{2}$ region. To extract the cross section with a highprecision, having reliable knowledge of QED radiative corrections is important.In this paper, we present complete numerical calculations of the lowest-orderradiative corrections in $e-d$ scattering for the DRad kinematics. Thecalculations have been performed within a covariant formalism and beyond theultra-relativistic approximation ($m_{e}^{2} \ll Q^{2}$). Besides, we present asystematic uncertainty on $r_{d}$ arising from higher-order radiativecorrections, estimated based on our cross-section results.
