Re: Fiestaware - Natural vs Depleted Uranium - Seriously This Time

Massimo, Thank you for the excellent report.. I noticed the Saucer has a little hump around 350 keV which seems to be missing in the cup, do you have any idea what it might be? Steven Yes, I noticed that too. I don't know what it can be. Not yet at least! I also would like to identify the small X-r...

Re: Fiestaware - Natural vs Depleted Uranium - Seriously This Time

So Massimo, how could I understand if my piece of Fiestaware has depleted or natural Uranium inside if I don't have any other information about it and if I don't have another sample that surely contains DU for a comparison? Reading your old thread I thought I understood that also the 77 keV xrf pea...

Re: Fiestaware - Natural vs Depleted Uranium - Seriously This Time

Part 2 And then it was time to take care of the cup. By the time I got there I started to think there was still a chance to find depleted Uranium in it, despite the saucer containing natural Uranium. The difference in the foot could be an indication the two pieces maybe belonged to two different set...

Fiestaware - Natural vs Depleted Uranium - Seriously This Time

Today’s post is about the world famous Fiestaware, a line of ceramic glazed dinnerware manufactured in the United States since 1936, with a hiatus between 1973 and 1985. According the New York Times “ Fiestaware is the most collected brand of china in the United States. It's also the No. 1 selection...

Re: Civita di Bagnoregio - Small, Beautiful and Radioactive Town

But gamma scouting in the presence of a group of people or family members can be a distraction. They tend to leave one behind when we are busy doing a count. Taray Yeah, that's the reason why I tend to go alone when the main goal of the visit is radiation measurement. But in the end being left behi...

Civita di Bagnoregio - Small, Beautiful and Radioactive Town

Hi folks, Last week I visited a small village in central Italy which is pretty popular with tourists, both locals and foreigners. The place’s name is Civita di Bagnoregio, not far from Orvieto. It’s a very small village first built some 2500 years ago by the Etruscans. According to official statisti...

Re: Chernobyl (Cs137) Contamination in Italian Soil - 6 Days Gamma Spectrum

I confirm what Steven says, calibration held very stable over the whole acquisition time (which, including the background acquisition, was a week). You can see it's a bit off when it gets to K40 but it was like that right from the start. Elsewhere it's pretty good, Cs137 peak is at 662 keV, right on...

Chernobyl (Cs137) Contamination in Italian Soil - 6 Days Gamma Spectrum

Hello there, happy new year everyone. As a Christmas present I bought myself a new laptop, so the old one went into retirement as far as work is concerned. That means he (sorry for not calling him “it”) can now stay at home doing gamma spectra when when I am in my office. That wasn’t the case before...

Re: A Day in Fukushima - Gamma Spectroscopy

And by the way, since I spent 9 nights in Tokyo I also took the chance to record a spectrum in my hotel room. Radioactivity in Tokyo is extremely low wherever you go, you rarely see a 0.10 μSv/h read, and when it happens it's usually a short-lived fluctuation. The spectrum shows usual background pea...

Re: Hottest Sample so far - Autunite Crystal from China

Since Radon is heavier than air, I think you should measure the levels near the floor where it's accumulating. A while ago I took part in a presentation about Radon in buildings and the observation was that highest levels were measured near pipes (gas, water, etc) entering the buildings. The fact a...
