I was also interested in taking spectrums from wood ash, but the low density is a real problem (considering my setup has rather limited volume for samples). Found out I can compress it much better if I pour in some water and then after pressing, I let it dry. Much better than what I can get by just ...

Most of the radon produced from the granite block will never escape it and would remain trapped until it decays though. Another thing is it might actually contain thorium rather than uranium which decays to a different radon isotope that has much shorter half-life. E.g my floor and bathroom tiles an...

I guess the biggest concern with tritium would be if you burn it to produce tritiated water, then drink or inhale the water vapor.

Hello Massimo, Yes, "dietary salt" gives a nice K40 peak. Keep in mind that it's not 100% KCl but usually somewhere in between 1/2 and 2/3, the rest is sodium chloride, magnesium carbonates and other stuff. Thus, potassium content is from 25% to 35% by weight. Pure laboratory KCl in contra...

Unfortunately, I rarely go to the Bulgarian seaside those days too. I did visit for a few days this year though. I guess though it would be difficult to find a "surprise" like that one there for one reason - our seaside is predominantly made of sedimentary rocks - limestone and sandstones ...

I've read some time while ago that black sands are composed of the heavier mineral fractions of vulcanic and/or intrusive rock and may sometimes have elevated levels of radioactivity. And a specific place where I often encounter spots of black sands on the beach is on Sithonia peninsula, Greece (I f...

R0B0T, I recently went on a short vacation near Sozopol, so I drove by that beach...unfortunately I didn't have time to stop by. Apparently though there is a huge camping site between Chernomorets and Atia. There were quite a lot of campers in tents. They were set up right on the beach. Is it like t...

Natural gamma background in some places (say the town of Samokov) measures higher than that. If you are interested, you can find some places where background is much higher (1 uSv/h and even more) right next to Sofia, those are the now-closed-but-poorly-recultivated uranium mines near Seslavtsi or G...

Good job!

Not quite into that, but I'd guess nothing, even fancy new methods can beat good old serological testing. On the other hand, I think cheap portable (well not necessarily USB) colorimetric or spectrophotometric device can be made that may automate/assist the personnel in the serological test procedur...
