A well proven Iodide detector with high sensitivity Caesium and a compact PMT used, the Nemo by Southern Scientific for its discreet size gives a very rapid response, making it an invaluable tool for finding (or avoiding) Gamma radiation sources.

The Nemo's simplicity makes it ideal for use even by non-technical personnel's. Gamma radiation when detected, Nemo displays from 1 to 9 a number and gives a vibration and a loud audible alarm. The nine preset are represented by the numbers 1 to 9 as alarm levels. Locating or avoiding a source by responding to the changes in the alarm and the response in the number displayed as the distance to the source decreases.

Unlike other instruments the Nemo continuously self-checks, detector voltage, count data integrity and monitoring battery level, for a reliable trouble free use. Low power consumption and the long battery life achieved from the non-volatile memory and the standard AA cells assures no loss in data logged while batteries are changed. Although Nemo is a standalone device, for viewing alarm events, as a standard an infra-red PC communication port comes is designed to meet IAEA recommendations monitoring at borders for Gamma radiation.
