Abstract：Objective To provide a basis for equipment disinfection during the epidemic of coronavirus disease 2019 via analyzing and
comparing the feasibility and safety of three common disinfection methods for the disinfection of special CT machines for pneumonia
in radiology department. Methods The 0.05% chlorine-containing disinfectant (A group), 75% ethanol (B group) and double-chain
quaternary ammonium salt (C group) were used to sterilize the CT machine for pneumonia respectively in our department. ATP
bioluminescence was used to detect the disinfection effect, and the significance of three wiping methods was evaluated by Wilcoxtest. Results There were statistical differences before and after disinfection in A, B and C group, but the opposite was true between
the groups (P>0.05). In addition, the variance of ATP detection value after disinfection was the lowest in C group, but the disinfection
effect of C group was the most robust. Conclusion All three disinfectants can achieve good disinfection effect, but C group is
convenient to work and the disinfection effect is stable, which can improve the compliance of operators. In addition, its low corrosion
and low irritability can ensure the safety of personnel and equipment better, so it is worth popularizing during the COVID-19 epidemic.
