Dangers of BeO ceramics???

toxicology is a difficult area. Nobody was able to tell me for example
how dangerous beryllium-oxide ceramics really is. This kind of material is
often used in small to medium argon-lasers. Since these lasers are quite
common for lightshows etc. (I have got such a laser, too) there are often
people confronted with this kind of material.
The answers I got on my question about beryllium-oxide ceramics ranged
from "No problem, like asbestos" to "Only plutonium is more toxic". The
standard book here in Germany, the "GIFTLISTE", where all chemical
substances are listed says that there is the suspicion that BeO-ceramics
might cause cancer.
My question is: (1) Does anybody know about the dangers of BeO-ceramics?
(2) Exists there any literature about this theme?
I am especially interested in the kind the danger is of. Is perhaps the
dust of BeO-ceramics dangerous if inhaled? (I think all aircooled lasers
(most of the disco-lasers are aircooled) release extremely small quantities
of such dust since the air is directly blown onto the hot BeO parts!)
Every hint is welcome...
