Since a voice output section (7), a power supply switch (4) and a power supply section (3) arranged at the mount/demount part A of an operating grip (1) are arranged to be mounted removably on the body section B of the operating grip (1), a radiation detector can be sterilized with sterilization gas, e.g. EOG, except for the voice output section (7), the power supply switch (4) and the power supply section (3) by removing them together with the mount/demount part A at the time of sterilization treatment using sterilization gas, e.g. EOG, and thereby breakage due to negative pressure at the voice output section (7) can be prevented. |
