We did see what looked like black lights being used on the ballots, but I believe most thought they were looking for a watermark. Then we had Jovan post something about every printer printing a unique code on every page, one that's not visible to the human eye because it's a small number of colored pixels. This is the first time I'm hearing about a radioisotope. Not sure of the validity of the article referenced in this post.

The isotope could be what became a "watermark" in the rumors. It serves the same purpose. This validates those theories
I'm also questioning the validity of the article. But machine identification codes exist https://en.m.wikipedia.org/wiki/Machine_Identification_Code
