Yeah, bionerd23 is rad. (pun intended)
She knows her stuff but she’s still a little crazy, but aren’t the best scientists always just a touch crazy?
If anyone here hasn’t seen her channel, go check it out. She’s been to Chernobyl on two separate occasions and encountered high level radiation sources on both trips. On one trip she found a tiny speck of reactor fuel buried about an inch below the ground. It was barely visible and reading upwards of 7 mSv/hr. She took it back to her hotel (do not try this at home kids) and ran gamma spectroscopy on it, sure enough: Cesium-137
