The possibility of induction of cytogenetic damage in the bone marrow, changes in the cellularity of lymphoid organs and blood composition in mice irradiated with low-intensity femtosecond laser radiation at a power flux density of 5.1, 10.4, and 52 mJ/cm2 (0.5 mW for 5, 10, and 50 s) in vivo was shown. Using the radiation adaptive response test (0.1 Gy + 1.5 Gy), it was found that, when mice were exposed to femtosecond laser radiation in high doses, the body's natural defenses were activated in the same narrow range of energy flux density (2-16 mJ/cm2) as in the case of X-ray irradiation in a dose of 0.1 Gy (4 mJ/cm2). The data obtained suggest a similar mechanism of activation of the body's natural defense upon exposure to low doses of both ionizing and non-ionizing radiation.
