This fool Craig in his video is talking bad about NETC when he is obviously clueless driving around with his DIY Mazur 9000 geiger counter. Just a little research on his part would have revealed to him that the TN radiation readings he cited in his video was actually an EPA RadNet gamma station (channel 5) and they use a scintillation counter, that is why the readings are so high.
Watch his video for a good laugh:
