Actually, this is not the first time this kind of radioactive snake oil appeared in Thailand.
A couple years ago, there was this "scalar energy" amulet thing which is also radioactive. The sales pitch include showing numbers on a detector that the salesmen claims detects "scalar energy"
By the way, yesterday there's a news article (on our mainstream media even) about a hand cranked generator that claimed that only 15 minutes of cranking will give 8 hours of 500W power.
So basically the majority of my country fails at science.
