Re: promotion film from BNC/Scionix

Hi Tom, I am not very good video or photo material so that must be the reason 😊 Hi Massimo, No we normally don’t give tours but now and then I did show a visitor(hobbyist) the company but I think I did it maybe 2-3 times only. The management is difficult to convince to let me do it, so I’m sorry! I ...

promotion film from BNC/Scionix

Hi guys,
You might be interested to see it, it is just a short promotion video made by BNC at Scionix.
Luckily I was free that day so I am not in the video.

Re: Hello everyone, nice to be part of your group

Hello Omar,
Welcome to the forum, I have got a question where did you work in Ecuador?
My wife used to work for the Atomic Energy Commission in Ecuador but that was about 27 years ago.

Re: Cs137 Italy

Hi Ciro,
Nice spectra still heavenly polluted by Chernobyl.
I still have a sample from north Italy with dried mushrooms, got it from a friend but up till now I never checked it, but seeing your results I must do a test with it for sure!

Re: Mirion PDS 100G, Spectrometric Personal Radiation Detector

Hi Ciro,
Yes it is a pity but the only way to detect neutrons can be done by replacing the standard detector by a CsI(Tl)/Lil(Eu) detector but that is expensive and
to get it to work properly it will need a new a factory callibration.
But still it is a nice detector as it is right now!

Re: Mirion PDS 100G, Spectrometric Personal Radiation Detector

Hi guys, As far as I know is the detection from neutrons based on PHD (Pulse Height Discrimation) and not on PSD (Pulse Shape Discrimination). That means that the detector considers every puls above a certain level to be a neutron. This principle is used in most portable detector systems, because go...

If your detector has a 22B28/0.75MCSTXN inside it can only detect gamma's

Re: Mirion PDS 100G, Spectrometric Personal Radiation Detector

Hi guys, Turning on the neutron option does not mean it can measure neutrons! There are two different detectors for these unit, the first one is just a CsI(Tl) crystals for gamma's, the second one is a combination from two crystals in one detector CsI(Tl/LiL(Eu) that is the only one that can also de...
