Man, a bit frustrating on this end. That purchase for the ludlum 3 and a couple rocks off Bonanza stagnated and was just sitting there unappreciated. 14 and 11 days respectively, passed since payment. Meaning though the money cleared days ago, week(s) in the case of my first purchase... No one even logged into the site to see that there WAS a purchase made since the 2nd of april.

I sent a couple emails off. Sent another several days later, and ended up having to call the guy up to get his attention, on my lunch break. Luckily hes at UNM( university of new mexico) and the PayPal email address brought me to his school where his phone number was listed. I was about to have PayPal close down the payment. It won't be here immediately, but the wheels are turning = good enough he did say it's(P3 pancake probe) sensitive enough to find U bearing minerals a foot under the surface of the ground. That is inspiring.

Emailed the seller from GSTubes.com and he still does not know, it's perhaps waiting to load up enough to send off at the shipping yard. My research into russian shipping seems like one of them things where it's ya know, a week or maybe 2 plus months... he confirmed and said it's first in last out, untill the pile is big enough nothing is sent. So still hoping for the best. He gets back to you in 24 hr almost every time, which is reassuring.

Between those two, the wallet hurts and it would be nice to see merchandise show up on the porch. But life keeps on ticking, a bit boringly at times, though ya can't complain about still drawing breath. It's a gift. Rambling and tired, I take my leave.

Some samples

I got a big package the other day. Two specific rocks, one of which was included the other mia and no email communication so far. There was an appropriately sized replacement, just the larger side of the first purpose bought rock. You can see the reflected pattern in the first pic. Little guy was like 33$and spot on. Other was labeled tyuyamunite, Yeah I'm confused. The Ludlum 3 with P3 probe. 4# of rock what just came with the geiger counter because, awesome. an 8" fiesta ware plate, actual pictures of professor (*?) Steve Buggie on location all kinds of extra info. A bnc to ludlum c connection or something. I've had precious little time to inspect the nerd treasure chest. Some of the rocks are pretty, some are dull. Like 14 or so foil wrapped and activity labeled rocks. 8 or so left to unwrap. That's the Rockhound_Steve guy on Bonanza.com/ User ID buggie4vrlhe on ebay, has cheap lumps of rock pretty affordably priced ... 6# lot of rocks for 30$ +13something $shipping. I have a hard time getting his attention though, the partial refund for combined shipping difference was fast. The Ludlum works great, probe is rad, capable of reading stuff from several feet away. And somehow amazingly, the parcel from GSTubes, that spent most of March, all of April and some of May in Russian federation, just popped up on the usps radar in Queens NY. Well played, postal service, well played. Had me nervous since the order was placed end of Feb. When I get the rocks unpacked I'll try to figure be some good pics. Think I'm good buying samples for a while. My whole collection fits inside a smaller styrofoam ice chest for shipping a ham, so, not so bad. Edit (*?) I was unaware that PhD title has a stigma around it, being called Dr. So and so perhaps is an unwelcome idea. The gentleman in question, has a PhD and did -not- refer to himself as Dr. It was my idea to do so, I thought it respectful to reference an achievement I don't have. Guess that a debatable opinion, and could reflect on that person in ways they may not care for. Whoops. And after calling today, yes I had to, I'm not any more sure I'll see the rock I wanted . But what eves, [Edited on 7-5-2021 by violet sin] Mailinmypocket International Hazard Posts: 1351 Registered: 12-5-2011 Member Is Offline Mood: No Mood Nice haul! I’m very jealous of that counter of yours! Maybe one day Does anyone know of any Canadian sources of radioactive minerals? I’ve searched and searched but there doesn’t seem to be the options that there are in the US, it’s quite frustrating! I could buy some from the USA or overseas but it just adds an additional level of complexity to something that’s already complex. On the plus side I finally received my SBT-11A tube, fun times! Note to self: Tare the damned flask. violet sin International Hazard Posts: 1363 Registered: 2-9-2012 Location: Back yard staring at stars Member Is Offline Mood: Good I bought more Ore... And two special ones from the seller on bonanza, Steve. Hands down best price. 30$ for 6lbs and like 15$shipping. If you buy specific rocks at same time you save on shipping, almost 20$ this time. But... You spend over a hundo on hot rocks, like 150$. Prices included for those that plan to buy samples in the future. Elsewhere a single rock could cost you 45$ +s/h and be super underwhelming in activity. United nuclear has some, sold out last I checked, that are exactly as mentioned 3-7k CPM for 45$. And there is nothing wrong with what they are doing... This is just better price. I look forward to actually getting to spend some time with these samples and daylight. Eventually, there will be display boxes... I promise. Enjoy the pics for now. (1) - the 135k CPM rock hits about 12k CPM by my GMC 320+ standards. ( * Side note * now imagine paying 45$ for one that only hits 3-7k CPM by fancy probe,,, measure with the GMC 320+ = frustration)

(2) - festive tin makes it just plain look like Christmas

(3) - assortment of rocks shoved in there ^^^ tiny foil wrapped gifts to your inner scientist. Complete with labels of specific activity on every one.

What you get from the grab bag besides physical U samples : Contrast and compare probes and machines to know what future sales from other sellers will seem like. Build comparison charts against his Ludlum 2200(?)(something like that) rate meter scaler with 44-9 probe. Dial in your 44-9 probe if your lucky enough to own one. If I'm not mistaken he uses an eberline pulser to calibrate his machines and those sold. So the descriptions are accurate. He also marks the fast activity areas with whiteout. Should be repeatable for others.

Fun hobby if you ask me. Better if the rocks were found, not bought... He offers a guided tour if you make it to New Mexico. Too far away, like 17-19 hrs. One day though.

(1) - laid out and sorted pile
(2) - big but only 19K CPM pic of active side
(3) - less active side of 28K CPM rock, flat and thin
(4) - active side with dot for hot area.

I intend to take a measurement from each side (3)/(4) and see how quickly signal is attenuated in matrix. Some is just crusty secondaries, very thin layers. some is matrix bound primary (black flecks) in unassuming rock.

The 3k CPM rock I opened ( not pictured) was nil on the colorful red sandstone side and hot on the ubiquitous honey brown side. There wasn't color or dark bits there. (Maybe UV would show something, but another time. Forum already ate one attempted post when previewing). And it only measured 350-360cpm on my gmc 320+ despite being a large rock.

Only opened a couple, if others look interesting I'll try to add more photos less me.

Mineral pics,

Not the easiest to photograph for me. But I got out the old stereoscope and shoved my phone up to it. Some details of the last lot of stones purchased.

1) I spotted blue mineral coming out of a few stones in small crystal flakes.
2) detail of stone in last pic
3) primary dark flecks(?) In matrix with secondary layers penetrating.
4) zoom out of same area, in general
5) point of a rock showing numerous minerals
6) close up of some secondary and calcite? Looks like calcite to me.
7) pinkish mineral associated with dark minerals and bright secondaries.
8) the colors pop with low light. Kinda boring from a distance, but neat up close.

I want to make a test bed to orient odd shaped stones over the detector in a way so as to be able to read the display and have control of the orientation of detector to source. Dollar store selfie stick works ok. Pinch type grip works on the detector, not great for stones, leaves the display in odd positions. It's a process, I'll figure something out, half the fun.

I found this piece of blue apatite, which I bought at a hippy Crystals & Metaphysical Bumper Stickers store in the mountains. I wonder if they realized how spicy it is (10-20 cps by my geiger counter). So sometimes you don’t have to look for explicitly radioactive minerals like pitchblend, but those that happen to often contain traces of radioactive elements

These sort of count as minerals

The woods behind my house were grown over an old landfill, and there’s stuff not far below the ground that sometimes floats to the surface. There was one spot that had a lot of old bricks, which was pretty useful. Another had a bunch of broken glass and old bottles and jars half-buried and incubating mosquito larvae. I was poking through the detritus when I saw a piece of clear green glass with a distinctive textured design; I was certain, looking at it, that it was uranium glass. Sure enough, it fluoresced bright green and was slightly radioactive (a piece would typically measure ~10-50 cps). I went back at night with my UV flashlight and unearthed more than a pound total of uranium glass shards. I also met another person out digging in the glass pile for cool bottles, and we had a sort of pen pal correspondence through a jar that we’d leave notes in for one another.

I also found a couple of pieces of ceramic, which appears to have a radioactive glaze of some sort. It’s not the usual orange/red fiestaware, but looks green-tinted and is
fluorescent. The small piece is ~30-60 cps.

For reference, my smoke detector americium source is ~20-50 cps from within a prescription pill bottle, and a 1% thoriated rod is ~0.5-2 cps.

Along the way I also found these bits of glass, which fluoresce but with a yellow-green rather than apple green and they’re untinted except for solarization. Not radioactive, but kind of cool looking!
