I have questions.

1. Is it true that Xenon 129 concentrations on Mars are higher than on Earth?
2. Is it true that, as far as we know, there is no natural process that produces this isotope in large amounts?

I want to say this is bullshit, because it seems like it implies some crazy schizo shit. I do not have the knowledge set necessary to discredit the claim. What do you guys know about it?

So, in summary, there are completely natural explanations for the much higher concentration of Xenon-129 isotopes on Mars vs Earth?

This is a question, not a statement.

NASA's cute website says that there are natural explanations...

What are they? Doesn't say.

> The chemistry begins when cosmic rays penetrate into the surface material. If the cosmic rays strike an atom of barium (Ba), the barium can lose one or more of its neutrons (n0). Atoms of xenon can pick up some of those neutrons – a process called neutron capture – to form the isotopes xenon-124 and xenon-126. In the same way, atoms of bromine (Br) can lose some of their neutrons to krypton, leading to the formation of krypton-80 and krypton-82 isotopes. These isotopes can enter the atmosphere when the regolith is disturbed by impacts and abrasion, allowing gas to escape.

There are more sources of radiation than nukes. It wasn't an ancient war, Mars just doesn't have a magnetic field or atmosphere like Earth's so it's been bombarded by cosmic and solar rays for potentially billions of years
