From: Survival of tumor cells after proton irradiation with ultra-high dose rates
Induction of apoptosis after irradiation. Cells were irradiated with protons (3 Gy) in pulsed mode (P) or continuous mode (C). Data are from 5 independent experiments except for data at 10 h (4 experiments) and irradiated samples at 0 h (2 experiments). Indicated are means and standard errors of the mean (SEM).
