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

Polimaster 1703MO-1A/B Gamma Spectrum Background Remover
Tagged as 1703, 1703MO-1A, 1703MO-1B, gamma spectroscopy, polimaster, software
Background photons can cloud your gamma spectrum and make life a little harder and so it becomes important to remove them. In order to remove them, I have written a small program in Java which does this. This program comes with no warranties and should be used AT YOUR OWN RISK. If it causes you problems, I apologize but you use the program at your own risk. I am working on a better version with a nice graphical user interface and additional features.
Installation Instruction:
Download zip file and extract to some desired location, perhaps c:\polihelper\.
Ensure Java Runtime Environment is at least Version 6 Update 30 or later (see how to check at http://ww2.valdosta.edu/vista/java_checkversion.shtml)
Take a background spectrum (without sample) for a period of time, perhaps 30 minutes.
Take a spectrum of the sample for the same period of time.
Use place the spectrum files in the same place as the program and run the program
Example: polihelper sample-spectrum.spe background-spectrum.spe cleaned-sample-spectrum.spe
Now, merely open the new file using Poli Identify and enjoy your cleaned spectrum!

Finding Uranium in Nature
Tagged as alpha, beta, electron, gamma, nuclear, pancake, particle, Radiation, radioactive, science, spectroscopy, uranium, x-ray
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
