The influence of thermal shielding on the bremsstrahlung cross section and the Gaunt factor is investigated for the transition bremsstrahlung process, using the effective Debye--Hückel potential in the impact-parameter analysis. The results show that thermal shielding suppresses the bremsstrahlung radiation cross section. It is also found that the maximum position of the bremsstrahlung cross section approaches the collision center with increasing thermal energy. In addition, it is found that the magnitude of the oscillatory behavior of the bremsstrahlung cross section decreases with an increase in the radiation photon energy near the peak impact-parameter domain. The thermal shielding effect on the bremsstrahlung Gaunt factor is also discussed.
