英文摘要The china spallation neutron source (csns) is going to be located in dalang town, dongguan city in the guangdong province. in this paper we report the results of the parameters related with environment safety based on experiential calculations and monte carlo simulations. the main project of the accelerator is an under ground construction. on top there is a 0.5 m concrete and 5.0 m soil covering for shielding, which can reduce the dose out of the tunnel's top down to 0.2 mu sv/h. for the residents on the boundary of the csns; the dose produced by skyshine, which is caused by the penetrated radiation leaking from the top of the accelerator; is no more than 0.68 mu sv/a. when csns is operating normally, the maximal annual effective dose due to the emission of gas from the tunnel is 2.40 x 10(-3) msv/a to the public adult, arid 2.29 x 10(-3) msv/a to a child; both values are two orders of magnitude less than the limiting value for control and management. csns may give rise to an activation of the soil and groundwater in the nearest tunnels, where the main productions are (3)h, (7)be, (22)na, (54)mn, etc. but the specific activity is less than the exempt specific activity in the national standard gb13376-92. so it is safe to say that the environmental impact caused by the activation of soil and groundwater is insignificant. to sum up, for csns, as a powerful neutron source device, driven by a high-energy high-current proton accelerator, a lot of potential factors affecting the environment exist. however, as long as effective shieldings for protection are adopted and strict rules are drafted, the environmental impact can be kept under control within the limits of the national standard.
