Radiation measuring apparatus includes a sensor assembly (10) including a sensor (16) which includes a scintillating body (30, 30') that absorbs radiation to be sensed and converts it to light. A measuring device (38) measures the intensity of the light emitted by the scintillating body and thereby indicates the amount of radiation to which the body (30) has been exposed. The sensor assembly may also include an optical fiber (12) by which the light emitted by the scintillating body is conducted to the measuring device (38). A plug (14) located on an end of the optical fiber remote from the sensor (16) is adapted to be detachably inserted in a connecting socket (40) of the measuring device (38). In this way the sensor assembly (10) is readily exchangeable for a new assembly.
