...yes, and don't use mobiles and so on.
Radioactivity is a concern, because I don't have any serious experience
with it. And I guess, many of us don't. And I totally lack a sense of
the amounts of radioactive radiation. I know well, what a Volt is or an
Amp and I know, where I have to put my fingers and where not on my lab
desk. Going down to my cellar may expose myself to some radiation, but I
don't work there for hours. Sitting at my lab bench for hours, daily, is
another thing, if there is a radioactive contamination of an unknown
radiation dose. Now, that we know, the amount is very little or zero,
we're all happy. That's all, not more, not less. I only wanted to be
cautious, and I guess, Hui, too.
The amount of Rb in a vapor cell is very little. You take in more radiocative
material by eating a banana. For the Rb to cause serious damage by burning, you
need to drop a couple
of gramms into water. Anything else will not cause a fast enough reaction.
Interesting.
Beside, you have only a couple of milligram, not enough to cause anythingm
major. Also, if the cell is broken it is most likely that the Rb is already
highly oxidized by the time you open it (and thus mostly harmless, beside
it's basic behaviour).
Yes. Broken glass is sharp and will cause serious cuts if not handled
carefully.
I think so. I only wanted to be careful with my advice, since I'm not a
physicist or a chemist. By the way: I don't eat bananas, but for some
other reason...
