Animals were treated in accordance with the Guidelines for the Care and Use of Laboratory Animals established by NIRS. TBI was performed at a dose ranging from 0.1 to 3.0 Gy for Fe particles (500 MeV/nucleon, 200 keV/μm), or from 0.1 to 5.0 Gy for X-rays (200 kVp, 0.5 mm Al + 0.5 mm Cu filter). The RBE of Fe particles to X-rays for induction of acute genotoxicity and late residual damage in the hematopoietic system was determined respectively at one and two months after TBI using the frequency of micronuclei in bone marrow erythrocytes as the endpoint. The health condition (body weight gain and the hemogram of the peripheral blood) was also investigated.\nResults and Conclusions: Reduction in a similar way of the body weight gain was observed in the groups exposed to TBI at high doses from Fe particles or X-rays. X-rays caused more efficiently hematological abnormality than Fe particles. Fe particles and X-rays reduced the ratio of polychromatic erythrocytes (PCEs) to PCEs plus normochromatic erythrocytes (NCEs), an indicator for bone marrow proliferation, in a similar way, while Fe particles resulted in more efficiently micronucleated PCEs and NCEs at low doses than X-rays. The relative effectiveness of Fe particles to X-rays for induction of genotoxicity in erythrocytes was higher at a low dose (0.5 Gy) than that at a high dose (3.0 Gy).\nAcknowledgments: This work was partially supported by both the Ministry of Education, Culture, Sports, and Science Culture Grant-in-Aid for Scientific Research on Innovative Areas, Grant Number 15H05935 “Living in Space” and two HIMAC Research Project Grants (22B258 and 14J286).
