PM1208 incorporates a sensitive Geiger-Muller based gamma detector and a stylish wristwatch, combining a leading edge dosimeter technology with Swiss tradition of the watch making. An audible alarm alerts the user when a potential radiation hazard exceeds adjustable radiation threshold levels. The instrument contains non-volatile memory to keep the measured data until they are downloaded to a PC by means of built-in IR interface. As radiation background increases greatly at high-altitudes, Polimaster recommends the PM1208M Wrist Gamma Dosimeter to frequent airplane travellers for monitoring of their radiation exposure.
