ABSTRACT=<p>Cross sections and rate coefficients for the formation of BeH<sup>+</sup> and BeD<sup>+</sup> molecules in Be<sup>+</sup> + H/D collisions through radiative association are calculated using quantum mechanical perturbation theory and Breit-Wigner theory. The local thermodynamic equilibrium limit of the molecule formation is also studied, since the process is also relevant in environments with high-density and/or strong radiation fields. The obtained rate coefficients may facilitate the kinetic modelling of BeH<sup>+</sup>/BeD<sup>+</sup> production in astrochemical environments as well as the corrosion chemistry of thermonuclear fusion reactors.</p>
