By the way, Trillium is a plant species, not a radioactive gas. Did you mean Tritium? Tritium is an Isotope of the element Hydrogen. H is the simplest element - a single Proton w/ a single Electron occupying a spherical ‘orbital’ space around it, Atomic Wt = 1. Tritium is a single Proton w/ 2 Neutrons in the nucleus & the single Electron, Atomic Wt = 3. It’s unstable & therefore radioactive.
But as I said, we need more elaboration as to what effect you think this is causing. It’s highly unlikely a radioactive gas like Tritium would cause any type of Urological symptoms - for one thing, it would be nearly impossible for someone to be exposed to it - it only exists in extremely minute quantities in nature & decays rapidly.
