Curing process method for radioactive nuclide polluted sandy soil

The invention provides a curing process method for radioactive nuclide polluted sandy soil, which comprises the steps of thermite preparation and curing process. Aluminum powder, ferric oxide powder and auxiliaries 1 are weighed by mass ratio of 0.33-0.66:1.00-2.00:0.01-0.30 and sequentially placed in a blender mixer to be stirred for 30-60 minutes at the speed of 60-120 r/min under the normal temperature and the constant pressure till the mixing is even. The curing process comprises the steps of mixing, dumping and embedding, ignition and post-processing. The mixing step is that the sandy soil with grain size smaller than 1cm and with SiO2 as a main component, thermite, auxiliaries 2 and simulate radioactive nuclide are mixed by mass ratio of 1.0:1.6-3.0-0.01-0.35:0.01-0.20 and stirred for 90-120 minutes at the speed of 45-60 r/min under the normal temperature and the constant pressure till the mixing is even. The dumping and embedding step is that a mixture obtained in the mixing step are dumped and embedde
