    Boron has 2 isotopes,  ¹⁰B and  ¹¹B.  

     ¹⁰B, one of the naturally occurring isotopes of boron, is a good absorber of neutrons and is used in the control rods of nuclear reactors, as a radiation shield and as a neutron detector. Boron filaments are used in the aerospace industry because of their high-strength and lightweight.
