An Alkali metal may be simple, but they are surely hazardous. Rb can be
extremely hazardous, as are the other Alkali metals, i.e. Lithium,
Sodium, Potassium and Cesium (and Francium, but that is one of the
rarest elements, due to its highly unstable nature, with its most stable
isotope having a half life of 22 minutes). They can react violently with
water, releasing hydrogen gas that may explode depending on the
conditions. Some of them will ignite with exposure to air. Note that
the small amount of Rb in a Rb lamp probably mitigates most of danger.

Rb is not even mentioned in the "The National Institute for Occupational
Safety and Health (NIOSH)" tables as a hazardous substance. Even if
shipped, Rb is listed as a simple Alkali metal.

Why are so many people radiophobic?
In my opinion, the answere isn't hard to find. Those people don't have
any experience with it and don't know, which information is correct.
Radiation can be dangerous, there's no doubt about it, is it? The
question is: is this paticular situation dangerous. So there's no sense
in mocking someone or making fun of him. We just need enough information
to estimate the risk. It would be better to inform someone who's scared
with precise information.
Rant off,
Since I'm no native speaker, I'm not sure, what exactly you are meaning
- declamatory, elevated, fray, excited?
Thanks
