r/caving

So just found out radon gas can accumulate in caves & had a quick google. Kind've shocked because one of the caves local to me (Giants Hole) is speculated as being one of the most radon-heavy caves in the world. It's also one of the most popular in the area with cavers (not a show cave, but was widened with explosives to attempt to make it into one)

Apparently levels of radon can exceed 155,000 bq m3 which is the equivalent of being exposed to about 0.73 mSv... idk if this would be considered dangerous? (Also, as mentioned, I got this from google so plz correct if wrong).

I've been into the cave 4 times (longest interval for maybe 3 or 4 hours) but didn't go too deep - actually prussik'd up into a chasm, rather than travelling deeper down. Idk if it's less likely to accumulate at higher altitudes?

I know people who have been on long & frequent trips through the cave, and it is frequently used for SRT practice. I'm very curious to know how much of a health risk this would pose, if anyone knows.

It has also put me off doing future "deep" trips into this system. Do you think this reaction is OTT?

Interested to hear your thoughts or more facts about this.

I spent five hours this past weekend learning how to do vertical rope work. Afterward I discovered that my left inner thigh is covered in bruises. My question is: does anyone know what I did wrong? Is it my harness? The way I am climbing? I want to go again but want to avoid the bruises in the future.

Been searching in my area for people to go caving with but can't seem to find any communities, I get told to just join a grotto. While I'm not opposed to the grotto idea, I don't have a lot of free time with work and other stuff I got going on so I don't think I'd be able to do that as much as people think. I'm planning on moving out of the area within the next year I'm just wanting to find one or two people I can explore with in my free time and not have to coordinate too much and take time off work. DM me if you're in the area, I have more questions than the post leads on. Not expecting much from this post but hoping I can get some useful information. Thanks in advance, safe spelunking!

I live in Kentucky and I'm looking for a cave where I can go explore with a buddy I'm experienced and just wanna find a non tourist cave to explore
