Abstract
It is proposed that the baryons in gamma ray burst (GRB) fireballs originate as "pick-up" neutrons that leak from a surrounding baryon rich wind into the baryon free fireball and convert to protons in a collision avalanche. Reasonable agreement is obtained with existing limits on the GRB baryonic component. The charged decay and collision products of the neutrons become ultrarelativistic immediately, and a TeV neutrino burst is produced with an efficiency that can exceed 0.5. Another signature may be lithium, beryllium and/or boron lines in the supernova remnants associated with GRB's.
