Abstract Objective To ensure safety of operations of 192Ir γ-ray defect detecting machine, surrounding dose rates during transportation, outdoors weld inspection and storage of this machine were monitored.Methods Based on external irradiation characteristics of this machine, and relevant standards, air kerma rate of the above three processes were monitored.Results The monitored air kerma rate of transportation ranged from 0.05μGy/h to 24.79μGy/h, outdoors weld inspection ranged from 0.05μGy/h to 0.27μGy/h, and the maximum of storage was 0.99μGy/h.Conclusion All of the monitored data did not exceed the relevant national standards, but some suggestions on radiation protection measures are proposed.
