  We have investigated the effect that dissipation may have on the cavitation
process in normal liquid $^3$He. Our results indicate that a rather small
dissipation decreases sizeably the quantum-to-thermal crossover temperature
$T^*$ for cavitation in normal liquid $^3$He. This is a possible explanation
why recent experiments have not yet found clear evidence of quantum cavitation
at temperatures below the $T^*$ predicted by calculations which neglect
dissipation.
