FIELD: physics, atomic power.
SUBSTANCE: danger detector for operation in nuclear field, having heating system for heating typically non-radiation hardened semiconductor components to increase functional service life. The invention relates to a danger detector (1), particularly a smoke detector for operation in an area (NUC) having a high radioactive radiation disposition. The danger detector (1) has at least one detector unit (3) for detecting at least one danger characteristic, a semiconductor component (5) and other electrical components (6), at least for outputting an alarm signal (SIG). According to the invention, the danger detector (1) has a temperature control circuit (20). The temperature control circuit (20) is configured to control the temperature of the at least one semiconductor component (5). The invention also relates to a danger detector (1) which can be designed as a linear smoke detector (200).
EFFECT: high reliability and longer service life.
