Product Description
Radioactive Ore Specimen.
The ore sample is Naturally Occurring Radioactive Materials (NORM). Uranium Ore samples are useful as check sources for testing Geiger Counters.
No analysis is performed on the ore sample. So the source of the ore's radioactivity may be any number of radioactive elements or decay products.
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 sensitive Geiger counter 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 an NRC certified Digital Geiger counter that has passed ANSI-STD N323A calibration using a NIST traceable source 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 any 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 are always in compliance 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.

Very disappointed in these, I suggest you buy elsewhere.
Also, no one else tells you, so let me say it here.
These are “NOT” returnable!
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.
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.
