The danger is that of a small particle (even very small) getting detached and ending up in your body, breathed in, or eaten, or... One would not want to run any risk of acquiring even a small amount of an alpha emitter than might become incorporated in your tissues. A low risk, possibly, but a low risk of a high risk event. I have a quantity of trinitite that I personally collected in 1949. At that time, it was capable of producing a good "buzz" in a primitive tube circuit Geiger-Mueller counter. In the late 1950's, it made only a mild buzz, and by the 1960's, no buzz. It was not as active as other samples I had, however, like a good lump of pitchblende, which was always noisier than the trinitite. By contrast, by the early Sixties, when the trinitite wouldn't raise a blip over background, the pitchblende activity was unchanged (as it will be for the next billion years or so). Nevertheless, I put the trinitite in a sealed but see-through container at that time (1960's) and there it stays. I did get rid of my radium samples, though, in an interval of sanity. The pitchblende and other ores are all in sealed jars. As for these exposures, anyone who was a child in the period of open-air nuclear bomb testing was exposed to a far greater hazard than that of owning (or handling) a piece of trinitite. See this testing: http://beckerexhibits.wustl.edu/dental/articles/babytooth.html and these results: http://www.physorg.com/news175368568.html Paradoxically, I handled the trinitite freely back when it was, well, a little "warm" and put it safely away about the time it had "cooled off." It's funny the way human logic works. The nothing-ever-happened-to-me argument is not a valid one in evaluating risks. When I was a school boy, I used to run into the show store at every chance and stick my feet into the fluoroscope they used to check the "fit" of a shoe, just so I could look at my skeletal toe bones wiggling. A public X-ray machine in a shoe store was a colossally stupid thing to have, but X-raying your feet as often as you could is pretty dumb, too. The fact that I seem to have had no harm as a result doesn't mean it was a harmless thing to do, but only that I was (am?) a lucky person. Trinitite is almost unique (and we hope it stays that way) since a combat nuclear weapon would never be (has never been) detonated at ground level. By all means, hold the trinitite in your open palm, then take a photo of it resting there, then put the trinitite away in a nice display box. Write on the back of the photo, "Here's me holding a piece of one of the paving bricks from downtown Hell." Sterling K.
