Dimensions: 8 cm | Very nice specimen with intense dark colour! Smoky quartz is one of my most favourite minerals (though my wife doesn't understand how one can love that brown/grey stuff ;-))

Hi Benj,
I see you keeping a strong radioactive mineral specimen in your bare hands.
May I advice you to protect your hands against direct contact with these specimens;
There will always be some molecules that will come loose and remain on your hands.
Then they may end up in your body through food contact with your hands.
You don't want that.
I'm just worried.
Also keep these minerals in a closed box as they may relase Radon.
Please read some literature about this.
Mathias

The topic of handling radioactive specimens has been covered many times before, but I will agree with MATHIAS.
When showing a specimen and including the owner's hand, the hand should include a covering. Otherwise don't include any uncovered body part in the photo.
When commonsense rules are followed, there should be no problems associated with collecting and handling most all radioactive minerals.
The rules include:
Have each specimen completely labeled, including a cautionary note.
Only occasional handing of the examples and then promptly washing the hands.
Never keep specimens in the bedroom or where food is kept or served.
Never keep specimens where children might play or might handle them.
Keep the specimens in adequate display cases or appropriately boxed up out of sight.
BOB

Hi Benjamin. Nice torbernite. I'd be proud to own it and/or fondle it.
All best wishes,
Ed in Kingman
