Re: Fiestaware (Depleted Uranium)

I'm sorry but I din't checked that part of energies, because I didn't know about the Protactinium :-(
I could try again, maybe with the Uranium glass together the piece of Fiestaware, to have greater activity...

Re: Tuff (Volcanic Rock)

Honestly I don't remember, I only remember I recorded the spectrum outside the Lead shield because of the dimensions of the block.

Re: Tuff (Volcanic Rock)

As usual, excellent work Massimo!
This, https://ibb.co/cYgpLm, is an old attempt I made with a single block.

Re: Fukushima Soil Sample "Reloaded" with both Cs134 Peaks

Hi Massimo, I think you're right but I'm not sure what you mean about the ratio.
You have a PM :-) !

Re: Fukushima Soil Sample "Reloaded" with both Cs134 Peaks

I couldn't help to make a test too, in the same way Massimo did :-) . This is the first spectrum with my faint Cs137 source (a Spark Gap TG36), 37000s 01-Cs137, SparkGap TG36, 36000s Background.JPG And this is the Fukushima Soil's spectrum + background subtraction. 82000s (45000s net.) 03-Fukushima ...

Re: Autunite (Uranium Ore) Spectrum

Good work, Massimo!
A took a spectra of a Pitchblende sample few days ago, in my lead shield but It wasn't good as yours.
I have to try the PRA's background subtraction, it seems to work very well!
