 note = {Irradiating hind legs of C3H female mice with single doses of carbon ions induced tumors at 200-1000 days. The frequency of tumor induction increased with dose for carbon ions and gamma rays.   A dose-response curve for 75 keV/um
carbon ions was steeper than that for gamma rays, while a dose-response curve for 15 keV/um carbon ions was rather shallower than that for gamma rays.   When isoeffect doses to induce 20 % tumor induction were used, resulting RBE values of carbon ions with15, 45 and 75 keV/um were 0.6, 1.0 and 1.4, respectively.
   Radiosensitivities of a tumor artificially composed of heterogeneous populations were studied. Tumors #6107 and #9037 are originally obtained by irradiating legs of C3H female mice with 
carbon ions and gamma rays, respectively.  Cells 
from 5th generations of each tumor were mixed
with ratios of 1 to 9 and 9 to1,  and transplanted into hind legs.  Dose-tumor growth delay time relationship of the heterogeneous tumors shifted toward that of radioresistant #9037 tumor after gamma-ray radiation.   Contrarily, the dose-response relationship of heterogeneous tumors after 74 keV /um carbon ions shifted rather toward that of radiosensitive #6107 tumors.},
