[en] The safety of workers at nuclear plants is provided by many ways. One of them is by using a radiation monitoring system. The monitoring system continuously samples the output of numerous radiation detectors and compares the values to predefined thresholds. One of the tasks of the monitoring system is to activate a local alarm system whenever the radiation level exceeds the predefined threshold for a specific location, When activated, the local alarm system initiates a siren sound and a blinking light to alert the operator in the area. The operator can silent the siren and stop the blinking of the light by pushing an 'acknowledgment button' placed on the front of the local alarm system. A steady light will still be on, until the radiation levels will drop beneath threshold and an operator will clear the alarm. The local alarm system that is currently in use has a 'blind spot'. When the radiation level exceeds the first threshold and an operator pushes the 'acknowledgment button' the system remains in idle state. The siren is off, the warning light is steady and it waits for the drop of the radiation level. An increase of the radiation level above second threshold will not change the state of the system and the workers will not be alerted. In order to overcome the 'blind spot' and to enhance the safety of the workers, an improved methodology for a novel local alarm system was developed. Enhancing the safety is provided also by hardware modification. A small alpha numeric LCD display was added in the front panel of the system. The current level of the y radiation field is displayed to provide a continuous local reading of the radiation level
