Re: PRA 17 Release

Very nice! As soon as I finish to calibrate my GS I'll surely try it.

Re: Old lead

I couldn't help trying to assembly a castle with the lead ingots, to make the test Max suggested. Castle_2jpg.jpg As you see the castle it's quite teetering and full of fissures, but it works respectably : with a 2"x2" NaI probe, it gives a background of 8.3 CPS against about 166.5 CPS on the outsid...

Re: Old lead

From bad to worse! :-(
Thank you Max for your detailed explanation.
I'll build it, by now it's a personal challenge :-).
I don't know when, but I will surely post the background spectrum once finished, hope within few months.

Thank you all again.

Re: Old lead

Hi Cicastol, thank you for the reply.
So you think this lead is quite useless...
By now I have it and I think I will continue with the project, but without great expectations ;-).

Re: Old lead

Hi Luuk,
thank you for your suggestion.
Maybe I can melt the lead seals into the same ingot to make the comparison you mean.
If I'll do it, I will sure post some other spectra.

Old lead

Hi all, a friend of mine provided me some old lead pipes, coming from an old house of the WWII times; so this lead has about 70 years and at least 3 half-life. I'm trying to build a lead castle with it, but the gross weight it's about 70/75 kg, not enough to make a "serious" shielding. So my aim is ...

Re: 210Pb in 67000s Lead shield background

Yes, very interesting, thank you Max!
These days I'm starting to collect as more informations as I can because I'm going to make my own lead castle, and I'd like to get off on the right foot.

Re: 210Pb in 67000s Lead shield background

Hi Cicastol, interesting spectra.
When you'll be ready, could you please post some spectra with the liner inside the castle?
It should be interesting compare the spectrum with and without copper, pewter, lucite (or PVC) ecc.

Thank you.
