We assessed the antimicrobial effect of low-concentration chlorine dioxide(ClO_2) gas against air bone bacteria in an indoor environment(a medical office of Showa university(66.5 m^3, live space)). Firstly, we calculated the number of air bone bacteria using air sampler in a medical office(control)(temperature and humidity was not controlled.). And then, safe low-concentration ClO_2 gas was generated in the medical office. Coming in and out at the door were not restricted. The concentration of ClO2 gas was stable at 0.01 ppm. 0.02 ppm approximately. When low-concentration ClO_2 gas was generated in a room, indoor airborne bacteria were reduced compared with the control level. This antimicrobial effect of low concentration ClO_2 gas was continued during the period that ClO_2 gas was generated. Low concentration ClO2 gas is effective for reducing the number of air bone bacteria in a live space.

我们在室内环境中评估了低浓度二氧化氯（CLO_2）气体对空气骨细菌的抗菌作用（Showa University的医学办公室（66.5 M^3，Live Space））。首先，我们在医疗办公室（对照）中使用空气采样器计算了空气骨细菌的数量（温度和湿度不受控制。）。然后，医疗办公室生成了安全的低浓度CLO_2气体。进出门的进出不受限制。 ClO2气体的浓度在0.01 ppm处稳定。大约0.02 ppm。当在房间中产生低浓度的CLO_2气体时，与对照水平相比，室内空气寄生细菌降低。在产生CLO_2气体的过程中，低浓度CLO_2气体的这种抗菌作用继续进行。低浓度CLO2气体可有效减少活空间中空气骨细菌的数量。
