Radon in Tap Water

[Persistency]

I may be moving to a new city in a few months, and their water apparently has slight traces of Radon. I was wondering if anyone knew what this would do to my fish, if anything.

Radon is an naturally occurring gas that comes from the ground in most cases. If from the ground its from uranium in the earth. In the air it causes lung cancer and in the water it causes organ and stomach cancers in people. I am not sure how it affects fish but, I would be more concerned about it evaporating out of the water from the fish tank and into your lungs as it is radioactive.
Thats all I know about.
