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.

我们评估了低浓度二氧化氯（ClO_2）气体对室内环境（昭和大学医疗室（66.5 m^3，居住空间））中空气骨细菌的抗菌效果。首先，我们使用空气采样器在医疗办公室（对照）（温度和湿度不受控制）计算空气骨细菌的数量。然后在医务室产生安全的低浓度ClO_2气体。在门口进出不受限制。ClO2气体的浓度稳定在0.01 ppm。0.02 ppm左右。当室内产生低浓度ClO_2气体时，室内空气中的细菌数量与对照水平相比有所减少。低浓度ClO_2气体的这种抑菌作用在产生ClO_2气体期间持续存在。低浓度的ClO2气体对于减少生活空间中的空气骨细菌的数量是有效的。
