Ok - so, if there is Radio Activity in Texas - and there is. And this Radio Activity can infect things such as Gold Bars and Related. Then can things like the entire United States Reserve of Gold Bars Stored in Texas become infected with Radio Activity? Yes.
The entire reserve has been sitting in a Texas place called Fort Knocks for about 38 Years. I would not put that in my pocket.
There is only one way to check the Radio Activity Level of Gold Bars. Litmus paper is no good because the testing sample can become infected due to Level of Radiation in the State of Texas alone. The proper way to check the Radio Activity Level of a Gold Bar is to bring it to Neutral area and check it with a clean Geiger Counter. (This is a Geiger Counter that has not been exposed to more than Level 6 parts per Million of Radio Active Particles in the environment. Also the Geiger Counter should have a field test done in a Hospital X-Ray Department)
Have a nice Day!
