Notes. Micronucleus frequencies were compared in bystander and sham bystander cultures, as well as in bystanders and sham bystanders that were challenged with 4 Gy γ radiation to test for adaptive bystander effects. Statistical significance is α = 0.05. Data sets marked with * are plotted in Fig. 3B.
