Product Description
Radioactive Ore Specimen.
The ore sample is Naturally Occurring Radioactive Materials (NORM). Our Uranium Ore samples are perfect for Geiger counter testing and educational purposes. Each sample is an unprocessed natural source of diverse radioactive materials. These samples, varying in size and activity levels, are measured for radioactivity using a certified and calibrated Digital Geiger counter. Ideal for enthusiasts and professionals alike, our Radioactive Ore samples come in a securely labeled metal container, shipped in accordance with NRC and Postal Service regulations.
Our radioactive ore samples may contain one or more minerals such as:
Tyuyamunite (green/yellow)
Uraninite (Black, Crystalline)
Pitchblende (Black)
Carnotite (Green/Yellow, Lemon-Yellow)
Uranophane (Bright Yellow)
Gummite (Orange-Brown)
Counts Per Minute (CPM) activity rate listed on the label is the activity level that includes all radiation types: alpha, beta and gamma.
Since alpha radiation is the main form of radioactivity given off by the ore sample, if your Geiger counter can not detect alpha radiation, it will show a much lower Counts Per Minute (CPM).
When checking with an alpha-sensitivee Geiger counte,r it is important to set the Geiger counter to its CPM mode and to locate the hot spot on the ore sample.
Each ore sample is checked and measured for its radioactivity using a Digital Geiger counter that has passed ANSI-STD N323A calibration from an independent government-licensed lab conforming to NRC regulations 10-CFR-34, 10-CFR-35, making the Geiger counter suitable for regulatory inspections.
License exempt. Radioactive ore sample size and CPM activity will vary. Shipped in labeled metal container as shown.
Disposal:
US Federal Regulations do not require special requirements to dispose of NORM material, however local city and state regulations may differ from Federal Regulations. One needs to check with local regulators on how to dispose of NORM material.
Shipping Information: We comply with Section 13 from part 40 of the NRC Nuclear Regulatory Commission rules and regulations and Postal Service regulations specified in 49 CFR 173.421 for activity limits of low-level radioactive materials. The item is shipped in accordance with Postal Service activity limits specified in Publication 52.

Customer reviews
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.

My sample came verified at 1150 CPM. My Mazur GC reads it as high as 5K! Definitely got what I paid for. I also like that it comes verified for a Beta & Gamma (no Alpha) level as well. Most of the cheaper GC's do not read Alpha so if you have one of those it's nice to know what reading you should expect in that application.
To avoid contamination, I left the sample in its plastic bag while I tested it with my S.E International Ranger Alert and my GQ GMC-600Plus. Both the Ranger and the GMC-600+ have open windows with pancake detectors. Here are my results:
Ranger readings:
Direct contact with the plastic bag = 9,400 CPM
Separated by a piece of paper = 6,400 CPM
With plastic cap covering detector hole = 1,650
GQ GMC-600+
Direct contact with the plastic bag = 6,700
The Ranger has a fine grid over the detector opening. The GMC-600+ has a plastic mesh covering a screen. So the sample was about 5 mm further from the GM tube and partially covered by the plastic grid.
My conclusion is that both the GMC-600+ and the Ranger are much more sensitive than the GCA-07W. The Ranger is the most sensitive probably due to the fine mesh protector and the proximity of the grid to the GM tube.
Btw, Amazon provided a star rating for "flavor" for this product. I didn't evaluate that.
So, I paid $7 for the right to say I ordered uranium on the internet, I guess, not bad, better than $40.
One thing, on the white container the warning says that the "specimen emits alpha, beta and gamma rays", I'm not sure about the beta or gamma, but I definitely feel the alpha rays because immediately after opening the container I got this impulse to drink beer and watch sports.

As you can see from the picture I attached, with direct contact to the Uranium sample my GC indicated a high of 6.874 Milli-Roentgens/hour of Gamma decay, and 24,060 Counts Per Minute of Alpha decay! The label on the can and bag the sample comes in says 2697 CPM when it was tested, so the technician must have found the weakest part of the sample when testing. This sample is stronger than I expected, but is still perfectly safe.
