 note = {We studied DSB induction and rejoining in the clamped and non-clamped transplanted tumors in mice leg after 80 keV/µm carbon ions and X-rays.  The yields of DSB in the tumors were analyzed by a static-field gel electrophoresis.  The OER of DSB after X-rays was 1.68 +/- 0.31, and this value was not changed by one hour rejoining time (1.40 +/- 0.26).  These damages in oxygenated conditions were rejoined 60 to 70% within one hour in situ.  On the other hand, no difference between X-rays and carbon ions was found for the induction and rejoining of DSB.  Thus, the values of OER and rejoined fraction after carbon ions were similar to that after X-rays, and the calculated RBEs of carbon ion were around 1 under both oxygen conditions.  The yields of DSB in vivo depend on exposure doses, oxygen conditions and rejoining time, but not the types of radiation quality.},
