It is presented to estimate yields of neutron and radioactive nucleus (7Be, 12B, 10C, 11C, 14C, 13N) per one p11B fusion reaction by the following 15 reactions : 11B (p, n) 11C, 11B (α, n) 14N, 11B (α, p) 14C, (α, n) of the structure material (SUS316) bombarded by α-particles, (γ, n) of the same and 11B (γ, n) 10B by 16MeV γ -ray of 11B (p, γ) 12C, 10B (p, n) 10C, 10B (α, n) 13N, 10B (p, γ) nc, 10B (p, α) 7Be, 11B (d, n) 12C, 11B (d, 2n) 11C, 11B (d, p) 12B, 10B (d, n) 11 10B (d, n) C and D (d, n) 3He, in the p11B fusion plasma with impurities of 10B and D. Result shows that the neutron yields by the other 7 reactions than11B (p, n) 11C, 11B (α, n) 14N, SUS316 (γ, n) and 11B (d, n) 12C can be neglected (< 10-7). Neutron yield and averaged energy by the above 4 main reactions are 2.27×10-3 and 2.49 MeV, and, 9.62×10-5 and 3.93 MeV from the plasma of Ti=300keV and Ti/Te=1, and Ti/Te=200, respectively.
