First, the mice were exposed to γ- radiation (whole body irradiation), then after 2 h or 24 h they were irradiated with laser radiation. The results of these studies have shown that the use of laser irradiation to reduce radiation damage in mice is effective 24 h after the exposure to 5 Gy ionizing radiation which leads to the bone-marrow clinical form of the ARS (Acute radiation sickness). In case of the lethal dose of ionizing radiation 7 Gy (the transitional clinical form of the ARS), the increase in life expectancy of mice is observed using laser radiation both 2 and 24 h after the exposure to γ- radiation, but the effectiveness of the laser used 2 h after the ionizing radiation is significantly more efficient.展开更多
