  We analyse the Dirac equation for slow fermions coupled to linearised massive
gravity above the Minkowski background and derive the effective low-energy
gravitational potential. The obtained results can be used in terrestrial
laboratories for the detection of gravitational waves and fluxes of massive
gravitons emitted by cosmological objects. We also calculate the neutron spin
precession within linearised massive gravity, which in principle can be
measured by neutron interferometers.
