Abstract：
The shielding for secondary neutrons has been estimated with the method presented by R.Madey et al.for the reactions of 0.6 and 1.2GeV/u 12C-ion on thick Cu target.The concrete shielding thickness of forward and lateral direction are 9.8,4.8m and 11.5,6.9m respectively when beam current of 0.6 and 1.2GeV/u ¹²C-ion are 1×10¹³ ions/s.
