Re: Liquid Scintillation Counting

Hello Steven, We are using clear glass vials with low content of potassium to lower the background, and 2 inches PMT for liquid scintillation counting. The method is most effected for beta and alpha radiation. Spectrometry is possible for both aforementioned types of radiation. The glass vial should...

Re: Radium vs Tritium

Nicely explained by WillemG! That is the reason, why drinking too much of heavy water (D2O) could cause serious problems in metabolism. But it does not mean that tritium in the GTLS (Gaseous Tritium Light Source) is dangerous. Tritium should not leak rapidly from GTLS, otherwise these sources can no...

Re: PRA 12.0.0 Out Now

Hello Steven,

I think it is good idea to include display of the pulse height resolution in percent within ROI!

Re: Martin M, Slovakia

Hi Martin, I am glad that here is someone from neighboring country, as I am from Czechia. Radionuclides which emit a beta and alpha radiation could be identified by liquid scintillation technique combined with spectrometric detection and alpha emitting radionuclides could be detected by alpha spectr...

Re: Does anyone have experience with PIPS detectors?

Hi Steven, I have not work experience, but we have one PIPS detector in the lab, unfortunately the company does not want to help us to complete old device and the new one is too much in cost. The PIPS needs any pre-amplifier and amplifier. I will searching any information for you, I will have a time...

I need an advice regarding PMT, voltage divider etc.

Hello guys, I have several questions which I am trying to solve. I hope that you can help me. I am trying to find datasheet for old PMT – RCA 4254/VI from sixties. This PMT with preamplifier is a part of scintillation probe with well-type NaI(Tl) detector. My search is still unsuccesfull. Do you hav...

Re: Chernobyl's Cesium-137 in Nature.

Hi Karl, thank you for informations. Sure, the fallout was quite heterogenous due to the weather during transition of contaminated air masses. For those who are interested in radiation monitoring I attach a link of "Radiation Situation Monitoring" webpage where are various data of radionuclides in m...

Re: Chernobyl's Cesium-137 in Nature.

Hi Karl, I know Sweden was contaminated much more than Czechoslovakia. I am interested in your measurements since I am interested in radioecology. I measured only one sample of soil from the most contaminated area in "Mosty u Jablunkova" village. But it was without shielding and I found mass activit...

Chernobyl's Cesium-137 in Nature.

Hello, I would like to present a selection of my measurements of Cs-137 in nature. I took the liberty to use my older presentation, which I wrote for an English exam. Since the presentation without words is useless, I slightly modified the original text and attach it (Comment) to read for those inte...
