i tested it with some mobile phones..depends on the camera, at first it needs about 10min calibration time but then works on my old sony Z3 with uranium ore
I have my one specimen in a steel cash box. Very inexpensive, and it has a lock on it so it is child-resistant. Make sure to label anything you get that is radioactive with 1) what it is and 2) warning of radioactivity.
You can get a detector for under $50 on Amazon. Amazon also carries the "Better Geiger" detector (scintillation detector) for a bit over $200 with test source. It's not a bad idea to take a detector with you into the field if you plan on looking for radioactive rocks.
I'm surprised at how inexpensive used pigs are on eBay. I had assumed that they would be more expensive.
I wouldn't personally keep them indoors.
I'd invest in an Airthings Corentium or similar to get an accurate measurement.
There was a video, since deleted, on YouTube of a guy who had a collection of 40 or so in his living room. He had to put them in a cabinet that was actively ventilated outdoors to keep the radon levels reasonable.
I've flown in an airplane with radium dials. Even though they give off a few hundred times background, short exposure isn't a concern.
I leave radium in the antique stores mainly for the radon concern.

I got this one, arrived in a few days. It is among the best I think. I hear the radiacode 101 has a more accurate spectrometer, it’s a similar product, but radiacode is based in Russia and I didn’t want to risk it, although they emailed me and said they ship from Cyprus so you may want to consider it.

If you're willing to put in the cash, which I assume you are... I'd recommend a steel lockbox instead, such as the one in the attached link. They work great for storing low grade samples of radioactive rocks. Slightly more radiation gets through, however this can be mitigated by a foot of distance as I assume your samples aren't all that "hot". With lead, I'd be worried about the toxicity as lead can get into bones and the bloodstream, causing brain damage and other types of illnesses. Not really something I'd want around my children. Plus, with this option, you can easily lock them away and stash the box in the garage. Lead containers provide diminishing return for their worth here as the radiation level is so low. I've had great success in the past with these types of containers as they store well even in harsh conditions and are easy to transport.
[Small lockbox on amazon, much easier to get.](https://www.amazon.com/dp/B07W6ZMTQ9?pd\_rd\_i=B07W6ZMTQ9&pd\_rd\_w=RZep7&pf\_rd\_p=7672bfb7-93b0-4322-b745-2104db09c4df&pd\_rd\_wg=Id5ok&pf\_rd\_r=JV8AA3WEMWC437BQV7XM&pd\_rd\_r=abc3c834-22c3-454a-9425-0f572ffdf141)
At the first view i had said its UO , many have this quarz lines inside but at the left side two botryoids are split in half, thats uncommon, normaly they brake away as one
If you have no counter but a smartphone get the app https://play.google.com/store/apps/details?id=com.rdklein.radioactivity
And follow instructions (tape camera with black tape, calibrate 10..15min...measure)
Uv light will show nothing on pure UO
If you want something fairly accurate, the GQ GMC 300e Plus would be good. From what I've heard, I don't think this Geiger counter is very good (although I haven't tried it myself, so I may be wrong).
Try looking on the Italian version of eBay (like others have said) or on Amazon.
(By the way, the nuclear reactor in Ukraine will probably not be dangerous to you if you live in Italy. It is built much better than Chernobyl was.)
you can use something like this too - bell jar
juts put a little silicone grease on the edge of the bell to improve the seal.
They aren't really bright enough and the "extra" bulbs I got did not work while the old ones that were already in there did. I found 1.5V bulbs that fit. I wonder if that would cause problems?
Sorry lol. This would be my recommendation if it’s in your price range since it detects gamma, beta and alpha which is good for seeing alpha emitters and it’s just a nice little handheld. Probably look into it more though for your specific needs and whatnot.
The Airthings one I mentioned isn't real time: it takes 24 hours to give you an averaged reading from the day. It does some kind of rolling average, and it will go up and down throughout a day. It's a good thing to have at home, too: I found out the air seeping into my basement is over 50 times what's safe.

These are made by Earth Archives. The list is not comprehensive too - a lot of important minerals are missing.
There is an excellent book called "Mineralogy of Uranium and Thorium" which I think is a "must have" for anyone serious about Radioactive Minerals.
The other one by the same author - "Introduction to radioactive minerals" is more or less a sub-set of the first book and it is somewhat redundant if you get "Mineralogy of Uranium and Thorium"
