  1. Although substantial statistical uncertainty is present, repair can be seen in most cases, with similar kinetics. No repair is seen for alpha particles, so repair half-times cannot be defined. A shared fit using a single repair half-time across all irradiation conditions does not perform significantly worse than individual fits, suggesting no difference in repair for different conditions (F-test p values in final column).
