if so,
yes mineoro detects ions but not gold.
uranium generally fonuds with gold and silver ores.

Hi Okantex,
"what about the gold of old times.are they pure?
or can be uranium inside of it's mixture."
I'm not a geo-degree but try to answer with what I know.
BTW This post must be technical oriented. (no simple words to talk about complex things! I'll try to make
it easier as I can)
I have realized that Mineoro claims its units "can find gold", not "gold of old times" but anyway let's
talk about old-gold.
Well, I know that old time gold has, generally speaking, a lot of impurities inside the matrix. Yes, it's
true. That's becouse of the old extraction methods and artifacts manifacturing in the past. Gold is a perfect
recyclable element (like aluminium) and may be re-fused indefinitely. So contamination could appear also
outside the "mine/ore" way - just by fusion, tools and manifacturing e.g. , for coins, the coiniage process.
But talk about uranium or other radioactive materials (mainly radium, thorium) : yes they can be present in
the ore/mine. It happens sometimes like in some Syberian mines or in the US also where gold and radioactive
materials are often in the same ore (some old Colorado mines are examples). It's rare instead in Egiptian
ancient gold (as I know) becouse of the native nature of the gold ore inclused in quartz crystals.
Also it's not so frequent in south-africa and australian gold mines. Don't know in South and Central America.
Anyway, it's possible that gold ore can be contamained by radioactive elements. So ancient gold could be for
sure.
All depend on how much is contamination in the mass unit and what type of elements and intensity of ionizing
radiations are developed. There are a number of variables involved like the percentage of elements, isothopes,
decading factors etc so a unique model of radiating behaviour is impossible to make before excavation and
analisis.
Another issue is that Mineoro can't detect airborn ions (or any other ion outside the so called "ion chamber").
Then why trying to find gold using radiations ?
The total ammount of radiation in an ancient gold artifact or bar could be thousand times lower than radon gas
trapped in the ground around the object or than the minerals that are in the ground matrix
- making impossible to reveal the target emission from the background radiations emission.
Another issue, is "why use a ion chamber instead of a normal geiger counter" ? I mean...if one would find some
radiations out there the geiger tube will overcome any ion chamber in such a task. Modern geiger counter units
are cheapy (say 200$) an hi-reliable e.g. 100 or more times respect to any small ion chamber, and they identify
ONLY wanted radiations (beta, gamma, alpha) - no radio stations etc.
Anyway, no gamma-rays, no alpha particles, no beta-rays can be related to a specific kind of primary element
(contamained gold or other metal) , just becouse they are always the same for every source of them.
Decading elements (like cesium isothopes) can be identified only using a mass-spectrometer in a vacuum environment
or other kinds of heavy and non-portable technologies. So any radioactive-to-gold interaction is simply undetectable
in a search field environment.
So it's impossible, this way, to make any specific element (gold) detection or discrimination.
Best regards,
Max
