A Q-TRAK IAQ Meter... was used to detect the airflow velocity and CO2 concentration. The luminance was measured using a TES-1335 Digital Light Meter (TES Electrical Electronic Co., Taiwan). Afterward, the number of individuals in the room on each sampling occasion was counted and recorded.""By comparing these two studies, it was found that the efficiencies were very different because in the present study, the space was not closed during the disinfection and people can come in and out freely."

****!!!!****** "UVC irradiance could not be detected in all the cases. For analyzing the UV content at the short distance, the measurements were conducted at the distance of 10 cm. Negligible amounts of UVA and UVB were detected at 150 and 200 cm from all CFLs." "In order to compare UV irradiance in three angles (0, 45, and 90), one-way ANOVA indicated that difference between three angles was not significant statically"

The results show that:when the concentration of chlorine dioxide gas is 0.3mg/m3,the sterilization time is 60min,the sterilization time period is from 20∶ 00to 21∶00(under fluorescent lights),sterilization rate to the atmosphere can reach 99.8%,and the sterilization rate to the objects' surface can reach 93.9%.Under the premise of human activity,it is the optimal sterilization conditions for hospital wards.

Gaseous ClO2 is chemically dissociated by light with wavelengths between 350 nm and 475 nm. They reported that the dominant (96%) dissociation products were ClO and O (atomic oxygen). It is important to take into account whether these dissociation products are toxic to humans. Judging from the short lifetime of O (39 ns), the toxic effect of this chemical, if ever present, would be negligible... High air temperatures and light irradiation accelerated the decrease of ClO2 gas concentration; the latter had the greatest influence. A quicker decay of concentration and greater value of the reaction rate constant of ClO2 were found under irradiated conditions, especially when a UV lamp was used... ClO2 gas concentration was significantly reduced when an evaporative humidifier was employed due to adsorption and a chemical reaction between the gas and the filter in the humidifier. The results obtained from these experiments can be used to predict the indoor concentration of ClO2 gas" "it was concluded that indoor humidity does not affect the reaction of the ClO2 gas" "an aquarium... filled with 10 L(2.64 gal) water was set in the room" "indoor ClO2 gas levels were lower in the room where water was present because the gas dissolved in water" "Ogata and Shibata (2008) reported that ****!! ClO2 gas concentration in virus aerosols is theoretically 0.12 µM when the aerosols are in equilibrium with 0.03 ppm ClO2 gas !!****, based on their revealed Henry’s equilibrium gas constant k = 3.9 × 10−5 mol 1−1 Pa−1. The present experiment showed higher concentrations of ClO2 in the water"
