Re: Boltwoodit

Hello, I got a small piece of mineral from namibia. It is Boltwoodit which is slightly radioactive. The fine yellow needles are easily recognizable. The spectrum shows very nicely the products of the decay series of uranium. Peter Boltwoodit-6.jpg Boltwoodit-7.jpg Boltwoodit-Spek.jpg Nice one Peter...

Re: Refurbishing project of a large 5”x3” NaI(Tl) detector.

Great work Luuk, the improvement is impressive, I can imagine the amount of time and effort required to get there. Svilen will definitely be delighted with it. I'd be curious to test a 5''x2'' to see how much more you can get from such a large size. Anyway, I have a complaint, you should have used t...

Re: Unexpected Radioactivity at Munich Airport - Lutetium 177?

Yeah, When Lu177 became my best candidate I googled "Lutetium 177 Munich" and I found: https://www.eusupplements.europeanurology.com/article/S1569-9056(18)31442-8/pdf http://www.klinikum.uni-muenchen.de/Klinik-und-Poliklinik-fuer-Nuklearmedizin/en/Nuclear-Medicine-Therapy/Prostate-Cancer-Therapy/PSM...

Unexpected Radioactivity at Munich Airport - Lutetium 177?

Hi there, This is the last thread from my recent trip to Japan. Actually, this post wasn’t supposed to exist at all. When I landed at München (Munich) I thought I was done as far as radioactivity measurement was concerned for the day, but it turned out I was wrong. I went through all the security ch...

Re: A Day in Fukushima - Gamma Spectroscopy

Hi Massimo and thanks for the nice and interesting report! I was on a Japan round trip in May and also visited Fukushima area. I can confirm all the facts that you wrote. Since weeks I wanted to make a report here, but there was always so many other things to do... besides I'm a bit lazy writing re...

Re: A Day in Fukushima - Gamma Spectroscopy

Thanks for your comments guys, I think sooner or later I am going to go back, and hopefully I will find more people and less red stickers. Very nice reports Massimo, both of them! Thanks for taking the time to share this experience and the pictures too. "Fear and misconceptions made far more victims...

Re: A Day in Fukushima

I can barely imagine what it was like to have friends and relatives in the area at the time of the earthquake and tsunami. I've read and studied a lot about Fukushima over the years so I had been thinking for a long time that it'd be interesting to see with my own eyes and measure with my own instru...

Re: A Day in Fukushima

Part 2 Next stop was Ukedo. There was a small town here with about 2000 people living in it. Looking at it from the newly built seawall it’s actually hard to believe it, the tsunami washed it all away, killing hundreds. 01 - DSC09870FR.jpg The only building still standing is the elementary school, w...

A Day in Fukushima - Gamma Spectroscopy

Hello there, And so it’s time for the Fukushima Post. On Saturday November 9 I left from Tokyo at 8:00 AM heading north. I entered the Fukushima prefecture about two and a half hours later and around 11:00 AM I arrived at Namie Town. Before getting into details here’s an overview: In little more tha...

Re: Ra226 spectrum from Scionix 35B57

Is this tiny 11KeV peak just noise or is it the low energy Pb210 gamma showing? ( blank arrow) -- If it is indeed Pb210, why would Theremino MCA be mashing the spectrum together a the low end? Nice spectrum Conor! I am aware of an x-ray from Uranium at 13.442 keV, but you don't get that from a Radi...
