Note to my beloved customers..... Before we talk about the item, I need to tear eBay a new garbage chute, the item listing is immediately below the rant. Thanks! Note to ebay: This is not a hazardous material. These are pebbles, small rocks, not unlike those pesky ones that get stuck in your shoe and bug you for like five hours until you finally give in and go through the ordeal of removing it. This item is shipped in compliance with USPS Publication 52, and is a natural mineral specimen, as it is clearly defined in 49 CFR 173.426. I have thoroughly examined dozens of listings for granite items without notification to customers that radiation being emitted by a single granite countertop or slab is exponentially higher than any rock or mineral I sell. That means by thousands of times, not a few times. In fact, if eBay wants to utilize my consulting services, I will gladly go to any shipping center and make sure that all items which are or could potentially be radioactive (the latter of which means literally everything and the former of which includes but is by no means limited to: fiestaware red, cream and black plates from nearly a dozen manufacturers (of which you carry perhaps 43,000 of those items at any given time?) which all contain an average 200x more radioactive material than the average specimen I sell. AND, unlike a properly handled mineral, can present a risk to health, albeit extremely minor, because collegiate studies have been done on the matter. a pretty tight group, even though it was probably another one of them who reported it. Who knows, though. There is a socioeconomic issue in these practices just waiting to come out. THE ITEM: This is an extremely dense uraninite specimen with pitchblende visible in many areas.nit is 22.8Gm, and gives off a whopping 300,000 CPM IN THE LOW ENERGY GAMMA RANGE, PLUS HIGH BETA AND SOME ALPHA ON THE SIDE, WHICH HAVE BEEN FILTERED OUT. I had to use the single channel analyzer on this specimen because I have a scintillation probe which mimics the 44-9 AND HP-270 probes with a quick calculation, and this just shot off scale.mremember, it is my problem to ship it, not yours. It will all be shipped within every pertinent regulation. Trust me... When you sell uranium,myou sort of need to know these things. I don't know how to price this offer. People at the office want to buy it. I will do 500 and entertain any offers. Scint probes were exactly at 801.25 volts loaded. I hope this goes to one of my coworkers, because I'm going to screw with you endlessly if I get bad feedback! This is a rare treat from Kern County, California. It was picked up more than a decade ago in several chunks during a joint EPA/department of energy venture (odd couple, right?) to clean up uranium mill tailings that amusingly enough contained more extractable uranium than most ores that were actually in the mines. That was my first job as an HP tech; and the constant 12-20 mR/hour field scared the living hell out out of me because it seemed so high. That was before I had ever set foot in a power plant, and way before I could consciously remember that time of exposure was equally significant to distance and shielding. This, as well as all the ore I sell, has been in a shielded part of an attic since 2000, and the stuff I keep finding gets more and more interesting as I go through it. Those of us who were mineral enthusiasts were able to grab a bunch of good stuff. I forgot about it until about a year ago. These It contains 44-60% uranium oxide (the pitchblende chunks in the sample make it difficult to assay) and a higher level of radium due to the pitchblende makes assay more reliant on imprecise spectrometry. Due to my own super conservative interpretation of milling laws, I don't break this stuff apart unless the ore itself is a host rock. It's not hard to justify doing, as the gamma level is strong enough to suggest at least a tad of a pitchblende deposit. When you sell uranium, you kind of have to be careful with the regulations! It's a really oddly-composed rock. The pictures depict it well. It looks almost like a dark granite in pattern, but it's speckled with black oxides. The alpha; which is the vast majority of radiation coming from uranium, is self-shielded because only the radiation from the very surface is measurable. Chunks and pebbles have a higher count rate because more of the surface area is exposed and detectable. Alpha and low energy beta are ridiculously high even with the self shielding; to a point where I'm not about to examine each and every detail with it held a few centimeters from my eyes for hours at a time. I would not dare to crush or grind unless you're in a lab. The heat is within, my children! I don't normally get to sell rocks that are the size, of, well, rocks! Most are too hot to fly. This one is sizzling, but with a bit of shielding and an abnormally large box, it will all be within regulations. Pancake probe: 102,500 CPM CDV 700: 8,000-12,000 CPM My continuous photon monitor: like twenty damn time in an hour while I worked with that specimen! Enjoy!
