Radioactive Uranium Ore
The majority of people who purchase these samples are going to use them to test Geiger counters. These machines need to be tested often to make sure that they are going to get proper results. You will be able to get a sample that you can store easily, and you will be able to keep it safely away from other people who should not be around it.
When you are purchasing these samples, you must make sure that you have a place to put them when you are receiving them. The samples can be sent in any quantity that you need, but you also must make sure that you are doing the things you need to store them safely.
When you purchase these samples, you can also use them for comparison experiments between more than one sample. You know that these Uranium ore samples are going to provide you with the radioactivity that you need for a baseline.
This is one of the best ways to get the samples for the lab experiments that you need. This is going to allow you to do the work you need to do without wondering what it would have been like to have the proper samples in the lab ready to go.
Apparently this stuff is legally radioactive uranium that can be shipped via snail mail. It probably will not power your submarine. It probably will not turn your turtles into ultra awesome and huge ninjas. It is probably not good to eat it. But, it is truly radioactive. Some people use it to test their radioactive detecting gear. Others are science teachers and use it in class as a cool object to show off. Others are terrorists. Just kidding.
