Nope.  That's cadmium or boron.  Be is sometimes used in 
sources mixed with Am-241 (called "AmBes" )as a source of neutrons
during reactor startup.  AmBes, sometimes with Pu replacing the Am,
are also used in the lab as sources of neutrons.

Some compounds are.

Very light weight, very strong, transparent to X-rays down to very low
energies, good neutron moderator, excellent heat conductor, as an oxide, 
a very good electrical insulator while being a very good thermal 
conductor.  Be is the lightest metal with any structural use.
