Spectrum Techniques Universal Computer Spectrometer UCS30 – A Review and Overview

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

A nice little unit, the UCS30 comes with 512, 1024, 2048, or 4096 channels. The unit has a built-in high voltage source and a pre-amplifier.

There are many great and wonderful scientific devices which we can obtain and use to understand our world. The most important things we can do in our lives are to learn all that we can and teach as much as possible to all who will listen.

The unit can be seen at http://spectrumtechniques.com/

Oh… and no, they didn’t ask or pay me to show off their unit. Unfortunately, I had to buy the unit myself 🙂

7 Days Later – My Radiation Dose for Seven Days

Tagged as , , , , , , , , , , , , , ,

And so it came to pass…

I wore my Polimaster 1703MO-1B gamma spectroscopic dosimeter for seven days to find out what my dose was. Of course, I only detected photon radiation from 40 keV to 3.5 MeV, and only external sources.

My total dose was 14.52 uSv

Which wokrs out to:
2.07 uSv / day

0.0864 uSv/hr

757.11 uSv/year

I estimate that my actual dose is much greater, at perhaps 2.523 mSv, but that is based on supposition and no actual hard evidence. 🙂

Equations (simplified for quick and dirty use!!!)

  2 * (E keV)^2
___________________ = Compton Edge
  511 keV + 2(E keV)

                  2 * (E keV)^2
E keV – ________________ = Back Scatter peak
                  511 keV + 2(E keV)

(Tom’s opinion)
Best source for calibration: Cs137
Best detecttor type: NaI(Tl) 1″ or greater!
Best free MCA software: PRA 8

Finding Uranium in Nature

A few weekends ago I went for a hike in my local city park (the park is actually part of a large chunk of woods) to look for radioactive rocks. Well… I found them. After only a short time, I found a vein of Uranium!

The video is long, but well worth it.

WOW! I got published again in Microbe Hunter magazine!

Autunite Uranium under long wave UV light

My samples of Uranium taken under a microscope were recently published in the September 2012 edition of Microbe Hunter magazine! Don’t forget to check out my previous published work in the same magazine, Microscopy Meets Gamma Spectroscopy – Modern Day Alchemy
