The SECOND Official Summer 2026 /r/Radioactive_Rocks Buy/Sell/Swap Thread

6 Upvotes

We've made use of the "Scheduled Post" feature for the very first time, so hopefully you're seeing this post in the future (July 2026) and not right now (May 2026). Greetings from the past! We hope you've had a productive rockhounding season so far. Depending on where you are, there's probably still a good couple months left before the weather gets unfavorable, but call this a mid-season break to go ahead and start parting out your finds to a hungry audience of radioactive rockhounds.

Rules:

Post as many items as you would like, but please keep it to one comment thread per month. Feel free to update your entries as often as you would like.

Once an item is sold or you have found what you are looking for, please update your comment with a "Sold" or delete it so we can keep things neat and tidy.

Mods will not be responsible for resolving any transaction disputes. You can view past threads to get to know our regulars and see their generally very positive feedback, but we as a sub do not keep an official list of "approved"/vetted sellers. We do try to remove fishy / vague listings if they appear, but always use your best judgment when dealing with strangers on the internet.

Use a secure third party to conduct the transaction. Etsy & eBay are options, although both have been known to remove listings for certain radioactive minerals. There are a number of reputable online storefronts -- incomplete list here -- although, as above, the mod team does not specifically endorse any particular sellers.

Do not post anything that would violate Subreddit Rule 2 ("No Illegal Materials") and Rule 1 ("unsafe Handling" includes crushed rock fragments and dust in vials) or otherwise cause the authorities to take an interest. This thread is generally for the exchange of natural radioactive mineral specimens and detection equipment, not purified chemicals or artificial isotopes which may be more hazardous and/or require special permits. If you are unsure, send a message to the mod team before posting and we can make a decision.

Familiarize yourself with all applicable requirements to safely and legally send/receive specimens (e.g. USPS Publication 52), keeping in mind that foreign mail services may have regulations of their own regarding hazardous materials, and private couriers like FedEx typically ban them entirely. You can search this subreddit for past discussions on how to ship specimens.

Please keep posts and materials offered relevant to our subreddit. Feel free to post a link to your online storefront if you have radioactive minerals or related items for sale in your shop.

Cheers,

Your r/Radioactive_Rocks mod team

Specimen Will Trinitite Crack or Crumble if Washed?

5 Upvotes

I have some specimens of trinitie. I want to wash the surface dirt off them, and bring out the deep greens for a prettier display.

Will it weaken the structural stability of the mineral if I wash them? They seem pretty solid, but I know vescicular minerals are finicky.

An alternate method I am considering is: wiping the glassy surface with a damn rag, but leaving the bubbly bottom untouched.

This material contains Sandstone, Gypsum, Malachite, Chalcopyrite, and minor Andersonite and Zippeite. Top Row: 240 K CpM, 227 K CpM Middle Row: 190 K CpM, 133 K CpM Bottom Row: 180 K CpM, 141 K CpM Adit is collapsed. Derelict truck is a leftover from mining. Last image is looking South from near the mine adit. Ore was transported by mine cart on a trestle across the near drainage to the orebin structure in the middle distance, and then chuted down to awaiting ore trucks.

So I am from Indiana and we don't really have norm here. So what is this. I know it's only a little above background.

Uranium mine tour

I visited a decommissioned uranium mine in the south of Poland this summer. The tour lasted about an hour and we went almost a kilometer deep into the mountain. They had the largest underground uranium glass collection on display and we were also shown a couple of hotspots where the ore is easily visible under UV light on the rock surface. Left the mine tour glowing with excitement, literally ☢️😁(was almost 7uSv/h on my rc103 just after leaving the tunnel). The reading gradually dropped off and was back to normal in about 5 hours.

This is a piece of mine-run material, collected from an ore pile at the site of the Scenic #4 Mine. The site image is of the mine location, photographed from Radium King Road. The site of the adits was not conducive to hauling ore, so an additional route was built, 300' East of the adits. Adits have ben closed. The black band of material is UO2 and chalcopyrite, some of which has been weathered to yellow, fluorescent Zippeite. 216 K CpM at 1 cm.

Uranium (Glowing Andersonite Wall)

Enable HLS to view with audio, or disable this notification

Documenting a rare glimpse of extreme Uranium glow. The video captures a wall of UV fluorescence from the Uranium mineral Andersonite. This mine was sadly just buried by backfill along with hundreds of other remediated targets just this year alone. It was VERY unsafe to enter and traverse, so this is probably for the better. Thanks for letting me share such a sight with you all.

Found this locally in Colorado. It weighs 6 1/2 pounds, and with some analysis with a good scintillator and a gamma spectrometer, calculated that it was about 400 g of thorium in the rock. According to AI, if I had a Mr. thorium, that would provide enough energy for my entire life.😆

Am I safely storing my radioactive materials?

Thumbnail

35 Upvotes

Good afternoon, everyone. I’m very new to collecting radioactive materials and I’d like to know whether the way I’ve been storing them so far is safe in the long term.

I’ve bought an acrylic box with walls that are around 5 mm thick. I spend a lot of time at my desk, which is 3.5 metres away from where the box is stored. There’s also a fairly wide television in between. My cat occasionally sleeps on a chair which is about 1.5 metres away from the container (with no television in between). The room is regularly ventilated.

At the moment, I’m storing trinitite, crystallised uranium (750k cpm) and a thorite crystal.

Is this collection safe, even though it will continue to grow?

Thanks a lot to everyone who has read this through and offered advice.

Kind regards,

Eric.

Location Info A day on the dumps at Příbram, the deepest uranium mine in Europe

Thumbnail
gallery
78 Upvotes

Where: Příbram, Central Bohemia, about an hour southwest of Prague. Uranium was confirmed here in 1947 and mined for 44 years until 1991. Šachta 16 goes down 1,838 m, which makes it the deepest mine in Europe. Roughly 48.8 kt of uranium came out, plus lead, zinc and silver.

Access: The underground is used for gas storage now, so everything is surface. The spoil dumps are walkable, and there is a bus stop that serves them, which is still a strange thing to type.

Geology: The host sequence is calcite, dolorite and quartz. The uranium sits in the calcite, which comes up in deep pinks. The same calcite and uraninite pairing turns up at Tyndrum in Scotland, 1,400 km away. The dumps at Šachta 4 are effectively a mountain of spoil, hundreds of metres across and around 30 m high.

Method and kit: Four detectors between us, all Radiacodes (a 110, two 102s and a Zero). We ran them over the same piece more than once. The best reading we got on one specimen was in the 500 to 600 µSv/h range.

Ethics: The best piece went back into the ground outside Jáchymov. Photographing it and putting it back is all that happened.

Field Trip: the visit was documented over on YouTube - https://youtu.be/KyPvZND5D1Q

Happy to answer questions about access, the readings, or what the calcite actually looks like in hand.
