This paper attempts to integrate RF technology into Nuclear Radiation detector circuitry. In the proposed system, a Nuclear Radiation sensor upon senses Radiation, activates its alarm, sends a low voltage signal to all the other Radiation detectors in the vicinity. This low voltage signal activates the individual relays in the other Radiation detectors causing to emit a tone that alerts residents, that one of the Radiation detectors senses Radiation. In this system the transmitter and the receiver are installed in a unit and the need for the base is eliminated. The individual Radiation detectors are equipped with all the electronics required to both send and receive signals. They are battery operated and therefore they require no external connections. They can be installed by a layman just on a watch tower. The proposed design is aiming to have cost efficient system, compact design, easily expandable, simple to install, replaceable components. The system was tested indoor with a normal test bench with the presence of artificial source.
