>>4323032>Wasn't cost?Not sure. I do believe there was some scare around it, but added cost is something the consoomers would slurp gladly in today's market anyways.
There is for sure a lot of scare surrounding it which has probably been nurtured from politics. I read about some dude that was into collecting thoriated glass had a package stopped because the USPS detected that it was above a certain threshold, so the system is for sure against it.
