Figure 4. Comparison of the Expression levels of the RAD51 Gene in Human Peripheral Blood Lymphocytes at Doses of 0, 0.2, 0.5, 2, and 4 Gy With 6 and 18 MV Photon Beams by Absolute Quantification.

A non-significant increase in gene expression level was observed at different doses of X-ray (except 2 Gy) with 6 and 18 MV beam energies.
