This is only the first 24 hours of use so I will not comment on whether it works or not, but I do trust banggood and I doubt they would sell us something touted to perform and does not. I have seen this number on the very same item put before the Geiger counter test and it passed.The serial number etched in the back of the pendant does match the card that comes with it. There is loads of information on these on you tube, people are calling these fake because they aren't the sellers brand. :)Īlways funny to read the reviews who bought this to 'get energy' and 'good health' like in the middle ages, and not too long time ago when people put thorium and radium to water, food, toothpaste etc. Good choice and working if you want to increase the chance to get thyroid cancer. I also tested this radiation is contains beta and gamma rays too what is go through your skin. This one is not hot like you can find youtube but for example the background radiation where i live is 0.1uSv and this pedant is 1uSv.

I attached the picture these pedants are radioactive, i bought because i was interested in is this true.
