I have an old Scitec MAP analyzer. It used a radioisotope as a source for XRF analysis of heavy metals in soils, etc. I had hoped to convert it to an XRF...
Henry, watch for Bicron scintillators with "X" in the nomenclature. Those *May* have a Be window. I have picked up a few for decent prices in the past, and...
BICRON 1XMP.040B-X NAI First digit is the crystal diameter 1= 1" XMP-X means X-ray M= "Monoline", which is the configuration where the tube is one piece-sealed...

Hi Henry, I have a LND 45432 Be windowed proportional counter tube. See http://www.lndinc.com/products/42/ for info. This has good sensitivity down to just...
Thanks for this information. I'll keep an eye out. Henry Henry Barwood Professor of Science, Earth Sciences Department of Math and Physics MSCX 312G Troy...
Hi Robert, I suspect your counter was used on a wavelength dispersive XRF rather than an energy dispersive unit. I have no idea what the resolution of a gas ...
Hi Henry, I don't know the exact details of the unit. It was and older model and the custom control console (computer) was missing. The 45432 data sheet says a...
Anyone happen to download a copy? Henry Barwood Professor of Science, Earth Sciences Department of Math and Physics MSCX 312G Troy University Troy, Alabama...
Hi Robert, I did some checking and the proportional counters have a lot better resolution than do the SiLi RT detectors, but the resolution differs with each...
Hallo friskey people. Does anyone have experience with infrared communication with victoreen 450?? I know that a module is required to be placed on the display...
<Id love a copy as well...i viewed it but didnt save it....crap > Me three. Although if you viewed it and it downloaded in its entirety, it almost assuredly...
... Thorium oxide has a molar mass of 264.04 g/mol. Thorium has a molar mass of 232.0381 g/mol. Oxigen has a molar mass of 15.9994 g/mol. (See wikipedia) So,...
... Hi George, using these atomic weights (and assuming they're correct): http://www.chem.qmul.ac.uk/iupac/AtWt/ You want to calcuate the ratio: Th/ThO2 =...
Perfect and thanks to all. I have a sample of ThO2, from this I will make a comparison ( gamma spectroscopy) with some mantles to determine the Th content in...

Don't forget to allow for the branching ratio.? Most of the gammas you will see come from either Ac-228 or Tl-208.? Th-232 decays to Pb-208. At Bi-212, there...
thanks for that link! I got it and it opened in Adobe ... but it opened in Internet Explorer and I can't figure out how to copy or lift any of the pages. (I...
I have hooked up this Bicron Scintillator600-2265 to a series 900 mini monitor and it beeped "wildly" went off scale.... My series 900 mini monitor have been...
Hello! What is the best (and safe) way to interface the output from a Geiger tube into a microcontroller? I'll start a new project soon and that part is the...
The pulse down from a geiger are hi voltage compared to a 3 or 5 volt microcontroller. You have to dscriminare them and reduce to a voltage to be counted by a...
Hi, What micro are you using? With Microchip pics you just need a DC blocking capacitor and a series resistor. The input protection diodes take care of the...
