A mobile type inspection apparatus for monitoring conditions in an environment or a facility containing radiation and a high temperature has a radiation dosage detector, a temperature detector, and a moisture detector disposed on a movable vehicle. Signals representing the monitored conditions are transmitted to a remote receiver which is included in a control system for operating the inspection apparatus and which has monitors for monitoring the conditions. Signals representing radiation dosage are supplied to a monitor and also to a comparison circuit for comparing radiation resistance limit data for the detectors which is stored in a memory with the detected data so as to generate a device exchange request when the accumulated radiation dosage exceeds the limit of any one of the devices. In a second embodiment, signals representing temperature and moisture are used for monitoring and also to calculate reaction acceleration and using time of the detectors to determine degree of deterioration thereof.
