One out of every 11,170 atoms of Potassium is Radioactive Potassium-40
with a 1.28 billion year half-life.
~ 11% of these emit a 1.46 eV gamma and/or a Positron which annihilates
with an electron giving off two 0.511 Mev gammas.
Discharge of the K+ ions on the Ti can form a gamma-emitting Potassium Titanate,
Or you can get a radio-stable "Calcium Titanate" or Argon 40.
How much Carbon-14 in the CO2? Could it get/stay in/on the TI surface? Ed?
