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...
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...
I've taken some rainwater spectra, sometimes the sample was surprisingly hot (like 20-30CPS) and they did have the radon byproducts photopeaks - Bi-214 and Pb-214. Most of the time it was below 10CPS though. BTW I've heard some people that have those Brita filter jugs discovered that the newly repla...
Hello Gents, Im interested in the Vromos Bay radiation ropic. I can provide you with sand samples as many as needed as I live near by. What does that mean??? The sand sample that I have - or at least about 100g of it - shows just about 11 CPS (125 CPS being the normal background in the room and 25 ...

Fear and misconceptions made far more victims than radiation around here This is indeed true. I just remembered when I was a kid, early 90s, there was a comedy show on the national TV and one day they decided to make "The NPP did just explode" joke. I even found an archive video, it has English sub...

I'd recommend ESP32, it's very cheap (you can have it for less than $10), it happily runs arduino sketches plus it's much more powerful and it has wifi/bluetooth and a lightweight tcp/ip stack. And it's surprisingly....well, working without issues. Much cheaper than the Uno yet much more powerful.
