Radioactive Uranium Ore Pyramid for Science, Collecting, Safe Handling of Radioactive Material. Geiger Check, Cloud Chamber, Uranium Glass... (Large)

My GMC-800 light up and fired off its loud alarm when I got within a few inches. So both items work very well! This pyramid is the real deal. I got 16 microseiverts. Can't wait to freak out my friends when they see the geiger counter lose its mind. :)

Exactly as described

So worth looking 11 hours of my life for

Very cool little piece, I ordered one of the smaller (not smallest) sized pieces. Looks cool, sounds scary on the Geiger counter but is not Dangerous enough to worry about. The one I have reads as high as 14 usv/Hr Right on it, but merely 6 inches from it, you read nothing more than standard background. Great for being “scary” conversation piece. Don’t sleep with it under your pillow.. that’s about all :)

I got this expecting to be able to at least "tickle" my geiger counter. No such luck. I've tried situating the meter in a number of different positions around this thing but all I ever see is background. I get that ionizing radiation is bad, particularly in excess. I just wanted a small weak source. This is not it. Two stars.

Exactly as advertised, radioactive indeed.

Pretty cool, good size

I don’t have a meter to measure it’s radioactivity, but, it’s encased within lucite and glows under UV-A light!
