Awesome! I've been following bionerd23's youtube channel for a while and really enjoy the videos she's done. Glad to see more folks being introduced to her too!
Genuine question from someone that doesn't understand. Is she exposing herself to more radiation than is safe? Is there a very high likelihood she's going to make herself sick? I watched this one https://www.youtube.com/watch?v=6kg4vVYKc90 and she seems to be pretty callous with that hot particle.
It certainly seems that she knows what she is doing, and isn't just jumping in for giggles when the meters start beeping. She even mentions the inverse square law in the video you linked.
