Re: Cs137 Italy

I've made a second bush airplane trip to collect soil on the Alps, the first sample was taken on a small flat,probably this accumulated and concentrated the rainfall during the Chernobyl fallout , causing an hot spot for 137Cs. The second sample wa staken 30meters away from the first place but on th...

Re: Lutetium ?

Hi Fer,
nice spectra!!
Yes my 3x3 is really outstanding in low end energy resolution, especially considering it is a big 3"x3" , something special happened under magical Luuk hand!

Re: Mirion PDS 100G, Spectrometric Personal Radiation Detector

Hi,
this are my settings, mine was checked with several energy compensated GM dosimeters i own ( Canberra ADM300,Thermo Eberline ESM FH40F2,Automess 6150AD2) and give all pretty the same results in a uniform radiation field (high radiation background in an Uranium ore mine).

Re: Cs137 Italy

Hi Massimo, pickup position : 45.747855, 8.042464 ,detector Luuk 3"x3", time 65ks, this long only to smoothen out NORM peaks, Cs137 will rise almost immediately! My goal is to use this soil to make exact efficiency calibration standard after a pro lab quantitative analysis, sadly in Italy is too muc...

Cs137 Italy

Hi, i've taken a soil sample in NW italian Alps at 1600Mt height , this place is known to be an hot spot for Cs137 Chernobyl NPP fallout , after only 1 minute the main photopeak is shown! Soil dried and sieved, total weight472Gr in Marinelli with Lead shield. Rough estimation of Cs137 activity is 29...

Re: Cs-137 contamination in Austria

Hi Milos, Eurostandard in your's country is one of the biggest supplier of isotopes calibration sources! According to a map of my soil pick up place, the surface activity was >25kBq/m2 in 2013, i will try to estimate the Cs137 activity based on calculated K40 efficiency of my detector with same geom...

Re: Cs-137 contamination in Austria

Hi,
nice report, can you give an estimated activity in Bq/kg ?
I've also taken a soil sample in a hotspot here in Italy (Valsesia) today, after only 1 minute integration time 137Cs peak is shown, it's like a calibration source!!!
I will post the spectra .
