Danger detector for operation in nuclear field, having heating system for heating typically non-radiation hardened semiconductor components to increase functional service life

摘要

A smoke detector or, more generally, a danger detector, operates in an area with increased radioactive radiation disposition danger detector has at least one detector unit for detecting at least one danger characteristic, a semiconductor component and other electrical components, at least for outputting an alarm signal. The danger detector also has a temperature control circuit. The temperature control circuit is configured to control the temperature of the at least one semiconductor component. The danger detector may be embodied as a linear smoke detector.
