My planet is richer in uranium than usual, so from the fission of U-238 and Pu-244, the long-lived Xe-136 would form, which could be released by geochemical processes, leading to an atmosphere rich in xenon. (In a unique layer full of radioactive elements between my core and mantle, I started with ≈0.1% Pu-244 from supernovae, which releases about ≈6.90e+41 atoms of xenon and i started with 10% U-238, which releases a larger number - from calculations on this source) | |
