Having had a party in Swedens first reactor R1, now de-commissioned
research and educational reactor, I kind of should have worried before.
Fact is... radiation wise it is one of the safer places to be, as they
have measured every square meter separately to ensure that it is only
background radiation left. They now use that reactor hall for dance and
music performances. Quite central in Stocholm actually...
We are straying too far away I fear. End story is that the small amounts
of Rubidium we play with isn't very dangerous radiation-wise. I worry
more about the fact that it would not be too nice to have direct contact
with it as it reacts hefty with water and the result of that isn't all
that nice. There is a thad of toxity too, but not very severly. I worry
more about the fumes from the PCBs I solder and the lead in the
solder... but usually not much at all.
It seems like suitable lasers for pumping Rubidium can be found cheap...
on ebay. Nice reference:
Points to Sharp GH0781JA2C, datasheet
2,80 USD each on ebay... well, why not get some and play a little?
