I have already provided two reasons why the resistance might vary:- 1) Aluminium coating. 2) Hydrogen absorption. Here is a third:- In an environment where ionizing radiation with an energy in excess of about 10 eV is present, additional atoms in the metal can become ionized providing excess free electrons. This will increase the conductivity of the metal. This effect is more pronounced with metals that are not very good conductors to start with, such as those used in heating elements. If excess energy is being created, then there is an excellent chance that such radiation is present, particularly if nuclear reactions play a role.
