Abstract：
Some results have been introduced on China-Italy DAMA cooperation--100kg NaI(Tl) crystal set-up experiments. There are lots of background problems need to be studied carefully, which would affect the results of DAMA experiments. Here, the radiation backgrounds in 100kg NaI(Tl) set-up have been studied by Beijing Group, and the Monte-Carlo simulation results are in good coincidence with the measurement of DAMA experiments. In addition, the contribution coming from fast neutrons' or solar neutrinos' interactions have been obtained through the simulation, which made very small effects on the experiments.
