Variance analysis of lymphocyte results. Variance analysis was performed to determine which experimental factor(s) significantly affected the lymphocyte counts in irradiated animals 3 hours (A) or 48 hours (B) after exposure. Radiation type (γ-rays vs. protons) and dose rate did not significantly affect the overall lymphocyte count after radiation exposure, whereas the total dose contributed significantly to lymphocyte count changes in the irradiated animals. Note: the x-axes labels are included at the top of each panel, i.e., Radiation, Dose Rate, or Dose.
