bruh, imagine flashlight malfunctioning. Nice video!

Reaches the end of the cave, and the light goes out….😳

one of a lot of dangers is that you could be breathing small amounts of radon gas, because uranium decays into radon gas

And radon decays into polonium, neither of which you want to inhale.

Would it help to wear a mask? At least you can avoid breathing the decay products like polonium and lead-210.

That's awesome, you're going through the caves scary I wonder what would happen if you turn the flashlight off very spooky thank you

I always carry 3 light sources with me. I had i happen that a light turned off, it's so damn pitch black it's scary. And better have the other flashlight easily accessible, since even getting ath out of e.g. a backpack is a major task when all you can do is feel inside the backpack and hopefully find the light and the on switch... Wasn't THAT neccessary in this mine, but there are others that go in way deeper, have shafts or deep water sections, or places where you have to crawl (see my Gustav-Jakob-Cave video e.g.)... you're basically doomed when the light dies in the middle of this one..

There's uranium ore in the stone. In the 18th and 19th century they mined cobalt, nickel and bismuth, in the 1970s when the atomic power hype started they were prospecting for uranium ore, again in the 90s, but the locals were against the mining of uranium then.

If you're detecting radiation on a geiger counter or dosimeter, you're basically not in any danger unless sticking around for long lengths of time. Uranium is used in vintage glassware, for example, which people eat and drink out of and are fine. Radium was also used on vintage objects, like watches and clocks. These items are very radioactive, but technically not very deadly. However, the people who painted those watches and clocks and compasses, they received significant doses of radiation, enough to cause illness and many deaths. But that was chronic exposure over years of daily ... ingestion ... yes, unfortunately, the 'radium girls' were told to use their mouths to point the tips of their paint brushes, which were of course filled with radium paint. Despite ingesting it dozens of times daily, it still took quite some time for them to fall ill. On the higher end of readings for geiger counters and dosimeters, typically months-to years of constant dose and on the lower end of readings, several hundred years or more of constant exposure is needed to incur a high enough dose to become sick. So unless you're maxing out your geiger counter or dosimeter, I wouldn't worry too much, although it is worth noting that you can breathe in radon gas, so if you're on the high end of a reading, I wouldn't spend more than an hour there at a time. Thing is though, geigers and dosimeters don't detect radon gas. But they can detect radium, which decays into radon. If there's a lot of radium or uranium (uranium decays into radium) in a confined space, such as a cave, radon will accumulate. So if you're getting very high readings and you know the mine is radium or uranium, you can bet that there is going to be a good amount of radon too. I'd personally not stay for more than an hour, but you'd probably be fine if you stayed longer. Radon is a problem for houses, because soils often contain radium and uranium and off-gas radon which can seep through floors into your home and accumulate with poor ventilation. Chronic exposure, like over several decades can be very bad and lead to lung cancer. Now if you're detecting ANY amount of radiation on a survey meter, something designed to detect only high amounts of radiation (like from a nuclear disaster), then run away, far away, as quickly as possible until it's not being triggered.

cool place. I would be far, FAR, FAAARRRR more terrified of becoming trapped in there by a collapse, or lost, or my flashlight dying than of a little radon though. What was that 1 -1.5 microSeivert per hour? Very very tiny dose for what couldn't have been more than an hour inside. I am regularly exposed to 10 to 100 times this level of gamma radiation working at an experimental fusion reactor facility. Not a big worry at all.

Good to hear that it wasn't that bad for my health :) Regarding light sources: always have at least three with you (main and backup flashlight - and cellphone).

@@F16_viper_pilot yeah, it's a fine low light source, just enough light to find the way back out and not fall into a shaft, even with low battery the camera flash LED holds long enough... and also to take photos while the gopro is headmounted. hope i won't need the last will function :):)
