  The type-II Dirac semimetal PdTe2 was recently reported to be a type-I
superconductor with a superconducting transition temperature Tc = 1.65 K.
However, the recent results from tunneling and point contact spectroscopy
suggested the unusual state of a mixture of type-I and type-II
superconductivity. These contradictory results mean that there is no clear
picture of the superconducting phase diagram and warrants a detailed
investigation of the superconducting phase. We report here the muon spin
rotation and relaxation ($\mu$SR) measurements on the superconducting state of
the topological Dirac semimetal PdTe2. From $\mu$SR measurements, we find that
PdTe2 exhibits mixed type-I/type-II superconductivity. Using these results a
phase diagram has been determined. In contrast to previous results where local
type-II superconductivity persists up to Hc2 = 600 G, we observed that bulk
superconductivity is destroyed above 225 G.
