Abstract
In this work, the Compton cross section of some materials such as aluminum, iron, copper, C45 steels and CT3 steels was calculated by Mathematica and Fortran 95 codes. Besides, the MCNP5 code and experiment using the gamma transmission techniqne to determine linear attenuation coefficients, were used to calculate the Compton cross section. The maximum deviation of about 6 % showed that our codes was good agreement with NIST data, MCNP code and experiment.

Summary
Tiết diện tán xạ gamma truyền qua để xác định hệ số suy Compton đối với một số vật liệu như nhôm, giảm tuyến tính từ đó tính toán tiết diện sắt, đồng, thép C45 và CT3 đã được tính Compton. Độ sai biệt lớn nhất 6 % cho thấy toán bằng chương trình Mathematica và chương trình tính toán phù hợp tốt với cơ sở Fortran 95 cho vùng năng lượng từ 250 keV dữ liệu NIST, chương trình MCNP5 và thực đến 2600 keV. MCNP5 và thực nghiệm đã sử dụng kỹ thuật Từ khóa: Tiết diện Compton, MCNP5, gamma truyền qua
