Figure 3From: In vitro characterization of cells derived from chordoma cell line U-CH1 following treatment with X-rays, heavy ions and chemotherapeutic drugsLET and RBE curves for three cell lines. RBE values were calculated from dose to get 10% survival fractions. LET 3 indicate 3 keV/μm for X-rays, 13 and 70 indicate 13 keV/μm or 70 keV/μm for carbon ions, and 200 indicates 200 keV/μm for iron-ions. Error bars indicate standard errors.Back to article page
