A sound output portion 7 , a power supply switch 4 , and a power supply portion 3 , which are provided at a detachable portion A of a manipulation grip 1 are configured to be detachable from a main body portion B of the manipulation grip 1 . Accordingly, upon sterilization using a sterilizing gas such as an EOG, the sound output portion 7 , the power supply switch 4 , and the power supply portion 3 can be removed on a detachable portion A basis. This in turn allows for using a sterilizing gas such as EOG to sterilize the radiation detector except the sound output portion 7 , the power supply switch 4 , and the power supply portion 3 , thereby preventing damage caused by a negative pressure in the sound output portion 7. |
