We report measurements of the in-plane London penetration depth. in single crystals of the alpha-PdBi2 superconductor-the alpha-phase counterpart of the putative topological superconductor beta-PdBi2, down to 0.35 K using a high-resolution tunnel-diode-based technique. Both lambda and superfluid density rho(s) exhibit an exponential behavior for T
