I love all this talk on O2 Toxicity and free radicals.  Boron is
neat stuff.  FYI, most commercial nuclear reactors use boron in
solution for reactivity control (PWR's that is). Boron added to
water to form B3HO3.  Boron-10 (about 19.7% in nature) is the
isotope with a 2E6 barn thermal neutron crosscection.  It is used
to hold down positive roe during new fuel load and is diluted about
3 ppm (natural boron, not enriched) per EFPD (Effective Full Power
Days).  When boron gets to zero, it's time to re-fuel (replace
about one thrid of the fuel assemblies.
Gosh!  I just love this talk.  Better diving through chemistry!
p.s. boric acid and alcohol makes great ear drops. 
p.p.s.  1% boric acid (1748 ppm) makes nice eye drops.
