Radiation therapy is used as the primary treatment for lung cancer. In this study, radiation therapy for establish ionizing radiation-resistant lung cancer cell lines (A549-IR/H1299-IR) was supported by Medicilon. 

The A549 and H1299 cells in exponential growth phase were treated with a repeated IR dose of 2 Gy each at room temperature and then returned to the incubator.
