SUMMARY

Studying and developing programs to calculate spread of Radon radioactive gas at mine areas.

A case study in the Nậm Xe - Lai Châu rare earth mine

Nguyễn Thái Sơn

This paper presents the research methods theoretical model and building program to calculated the spread radioactive gas radon from the mining areas to the neighboring residential area. Based on theoretical modeling algorithm, the authors have used the Gaussian model to calculate the spread of radon concentration for the areas source format. From the theory of Gaussian models, the author has developed the program calculates the spread of radioactive gas radon taking into factors affect the spread and apply thc program to calculates the radioactive emissions radon in rare earth mining areas Nậm Xe - Lai Châu, 2015. The calculated data matches thc documents had collected 111 this area.
