Rb87 has a halflife north of the age of the planet as far
as I recall, and the result is a beta which goes nowhere
far and Sr87 which is stable.
He got a lot more ionizing radiation from his cigaretess than he
ever got from the Rb87.
Just for the heck of it, I'd go laser instead of the old UHF lamp.
With respect to precision machining, that space has changed a lot
over the last five years, with precision CNC machines, factory
or home-built, dropping dramatically in price.
