No compound or spectral analysis is done on the radioactive ore sample. Therefore the origin of the ore’s radioactivity isn’t determined and may be any of, or any variety of radioactive elements like uranium, thorium, and potassium as well as some of their decay products like radium and radon.
Counts Per Minute (CPM) action rate recorded on the tag is the action level that contains all radiation types: alpha, beta, and gamma.
Since alpha radiation is the most important type of radioactivity given off from the ore sample, not having the ability to detect alpha radiation will yield a much lesser Counts Per Minute (CPM). Inexpensive Geiger counters can’t detect alpha radiation.
When checking with an alpha Geiger counter it’s crucial place the Geiger counter to its CPM style and also to find the hot spot on the ore sample.
Each ore sample is assessed and measured for its radioactivity with an NRC accredited Digital Geiger counter which has passed ANSI-STD N323A calibration with a NIST traceable source from an independent government licensed laboratory adapting to NRC regulations 10-CFR-34, 10-CFR-35, making the Geiger counter acceptable for regulatory inspections.
License exempt. Radioactive ore sample size and CPM action will be different. Shipped in labeled metal container as shown.
Shipping Information: We’re always in compliance with Section 13 from part 40 of the NRC Nuclear Regulatory Commission regulations and rules and Postal Service regulations specified in 49 CFR 173.421 for action limits of low-level radioactive materials. The product is sent in accordance with Postal Service action limits specified in Publication 52. Radioactive minerals are for scientific and educational use only.
