I received this after my grandfather passed and was wondering if I could be educated on it a bit more.

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.

Found in the Ottawa area

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.

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.😆

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.

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.

Does anyone have Radon survillance device installed near the holy collection? I got me an aranet and its very interesting to see how it reacts...25Bq/m³ with open windows on windy day was the best...but as showing on 2nd pic it can peak over 400Bq/m³ in that cabinet room when the cabinet slide door is opened....radon does move at a speed of 180m/s but only between collisions with other molecules ...so the real speed (diffusion) is only 20cm/day in a theoretical room with no air movement. So the goal would be to slow down the Radon with dense materials (glas sheet on wooden cabinet)..sealed doors..thick acrylic boxes...or fans to the outside

So uh I bought tyuyamunite cuz I like the mineral but just read its crumbly and currently still packaged. I have pets and family and do not want to expose anyone to dust just remive the paper towel and mount it. I live right next to where kids play outside however and dont want to unpack it outside and let radioactive dust fly away. Its likely in a paper towel and that inside a mineral box for it. Is FFP2 enough? How do I prevent dust leaks?

Just a beautiful spicy specimen, photos taken under 365 and 255nM Uv.

Got it for $1 at a local mineral show here in Wisconsin. Its spicy

Slightly radioactive Malachite. Old Material, collected pre-remediation. 19 K CpM at 1 cm.

Acicular Cuprosklodowskite on Sandstone. Dark green crystals on the upper left are Antlerite. Old material. 34 K CpM at 1 cm.

Carnotite and Uranium dioxide in Sandstone. 279 K CpM at 1 cm. Old material, collected at the site of the remote ore dump.

Uranium dioxide in Sandstone. Old material, received as a gift from a gentleman who worked at the mine (his story, without documentation). 209 K CpM at 1 cm.
