The only naturally occurring isotopes are 231 Pa, which occurs as an intermediate decay product of 235 U, 234 Pa and 234m Pa, both of which occur as intermediate decay products of 238 U. 231 Pa makes up nearly all natural protactinium.

The recovery of 234Pa can be followed in the aqueous layer if desired. About 95% of the protactinium is removed together with some uranium when the bottle is shaken. In nuclear science, the decay chain refers to a series of radioactive decays of different radioactive decay products as a sequential series of transformations. It is also known as a "radioactive cascade". Most radioisotopes do not decay directly to a stable state, but rather undergo a series of decays until eventually a stable isotope is reached.
