RF burns are a lot different than electrocution-style burns, though. But I'm not an expert on either topic, I'd defer to some people who know more about it.

- MisterTea 2y ago> electrocution-style burns Do you mean burning via resistive heat dissipation from current flow through flesh? There are also burns from plasma in arc discharge events. An arc discharge to the body can produce both.
- timr 2y agoDefinitely, but this video is not that.
- geerlingguy 2y agoSame disclaimer: I'm not an expert on this... but I have been talking a lot about RF burns and arcing with RF engineers, and I think there's more nuance to this. It would be interesting to see the difference grounding a hot dog through 7 kW AC (60 Hz) and seeing any difference in internal heating and arcing. Maybe a topic to explore in another video—especially if I can get access to a transmitter manufacturer's testing lab...
- timr 2y agoSure. I'm not trying to suggest that it isn't a factor at all, just that it's not what's ablating the hot hot dog/pickle in this example. I wouldn't want to sit next to a working AM tower and have lunch or anything.
- runjake 2y agoAnecdotal: I was cooked by some pretty powerful ECM [electronics countermeasures] gear, because an ECM officer was dumb and had his equipment turned on while on the tarmac. My abdomen was up against the area where the antenna was, about 6 inches away. No outward signs of injury, I just felt an internal burning sensation and severe nausea pretty quickly. I was feeling okay after about a day or two. I never did get checked out by medical, so no clue of what permanent damage was done.
