Ruggles Uranium Mine Trip! (Uranium Mine)

Filed under Radiation, Science
Tagged as , , , , , , , , , , , , , , , ,

I traveled to Ruggles Mine, New Hampshire to find uranium (and other minerals too!). The trip was fine until I learned I could not use my radiation detectors… which was terrible news! They did sell burgers and drinks and even had uranium for sale in the giftshop lol WARNING! There is uranium on-site, so keep control of the kids or don’t bring them. No need letting children get too close to uranium.

Pros:
Large area to mine.
Loads of minerals.
Wonderful giftshop.
Food on site

Cons:
Cannot use radiation detectors! 🙁

Beautiful Uranium

I love Uranium! What a wondrous, mysterious, powerful, and somewhat dangerous element. For thousands of years humans have used this element for colorant and more recently for energy. As amazing as Uranium is, did you know how beautiful it can be?

These pictures were taken under a digital light microscope, in my laboratory, at magnifications of 40x to 400x. The specimens used were tiny grains of uranium many times smaller than a grain of salt. As beautiful as these pieces are, breathing one into your lungs could be quite serious! I worse a dust mask, gloves, goggles, and took full laboratory safety measures when working with the Uranium. My Geiger counter and scintillation probes were on and in use the entire time. I estimate that my hands were exposed to as much as 2 uSv of gamma radiation at contact and that my entire body dose, aside from my hands, was about 0.1 uSv for the period of the work. This is only 2.5 times my normal background of 0.04 uSv/hr*

I found these marbles at my father’s house. Uranium has been added to lots of consumer products over the years, often because it makes the products very beautiful.

Also, be sure to see my other uranium\thorium videos:

Radiation and Uranium are amazing and powerful.

Like many of natures most powerful creations, Uranium is dangerous and must be treated with respect. Never expose children, pets, or your bare hands to Uranium. If you should ever touch a Uranium sample, always wash your hands carefully.

Remember, distance, time, and shielding, and hand washing are your friends.

As always, don’t try this at home

Autunite

Autunite - Uranium


Autunite is a very beautiful, many might say the most beautiful, uranium-bearing mineral. Autunite contains many amazing isotopes, including a few transuranic elements! I received a sample of the beautiful and deadly mineral from a friend at the cost of an analysis using my gamma spectrometer.

I have finally completed a calibration analysis of my spectrometer, to include a 17 KeV to 2MeV window with a +/- 3KeV tolerance. These are favorable conditions for analysis of uranium and uranium daughters.

Today, I tested my new Autunite sample in my gamma spectrometer to see what I might find within it’s calcium-encrusted innards. The primary natural uranium products are there, as expect: Lead 214 and Bismuth 214 being heavy gamma emitters, lead the way with large spikes at 351.92 KeV, 295 KeV, and 609.31KeV, 1764.49 KeV, respectively. I detected a tiny bit of Radium 226, Uranium 235, and Uranium 238.
