The latest is an email from a Russian reader, G.O.:
Beryllium oxide powder is extremely deadly.
The killer is beryllium oxide which causes berylliosis — a progressive chronic disease similar to asbestosis but with a very fast incubation period; it usually kills in few weeks. One inhale of beryllium oxide dust is a sure death sentence. No cure.
Before the danger of Be-oxide was recognized, workers involved in the fabrication of Be-ceramic died, also died their families and even pets. In the USSR communal apartments all the occupants of Be-contaminated apartments died. (People brought minute amounts of Be-oxide on their clothes).
Beryllium oxide is a superior ceramic; it has a very high temperature work range — over 3000 degrees Celsius. Most remarkable (and unique): Be-oxide is good a dielectric at very high temperature. Be-oxide is similar to aluminum oxide in mechanical properties and adhesion to the base metal. This is the reason why Be metal is relatively benign – unless it is ground into a powder. Fine Be oxide powder is indestructible and extremely deadly.
So… even though beryllium is not radioactive, it sounds like it might be dangerous in the hands of the terrorists.
