I am currently running few S2 Antminer and taking it apart and seeing what is inside indeed make me wonder is it really toxic. I had purchase a meter from ebay to test the radioactive reading. Each S2 cards resembles a graphic card and nothing more. I wonder how toxic can it be. BTW i believe 80% of electronics from the world are from China so lets not stereotype.
Thanks
I don't think its radioactive, but the air that come out from S2 antminer should have metal smell which isn't really good for human body..
