Andersonite, Zippeite, minor Malachite, Chalcopyrite, Sandstone, Uranium dioxide, 102 K CpM. Second image is under 365 nm UV. Obvious difference in the visible emission spectra of the two minerals Zippeite and Andersonite. Third image is one of the adits of the Markey Mine before remediation.

Six specimens from the Blue Lizard, Each is composed of Sandstone, Chalcopyrite, Limonite, Pyrite, Uranium dioxide, and the vivid green Johannite. Top row: 137 K CpM, 167 K CpM Middle row: 189 K CpM, 182 K CpM Bottom Row: 107 K CpM, 143 K CpM. Site picture is of the mine building, sitting on the top of the mine waste. The adit is blocked and is not visible in this image. All collected prior to closure of the adit.

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.

The relatively common falafel variety.

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.

Found this clearing an old collection

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
