| Based on the fireworks and firecrackers industry in Hunan, the main source of radionuclide contamination of fireworks and firecrackers was investigated and analyzed in this paper. The portable γradiation dose detector was used for rapid determining the total content of radionuclide in the main raw materials and all of the products from the factories in Liuyang, Liling, Changde, Chenzhou and Shaoyang of Hunan province. The results showed that compared with the local radiation environment, the fireworks and firecracker products and its raw materials were not polluted significantly by radionuclide contamination. |
