Personal radiation dose has decreased as years pass by. This requires a personal dosemeter with higher sensitivity. Recently new dosemeters have been developed, such as the Luxel badge that is composed of Aluminum Oxide (Al2O3:C) as a detector element with an optically stimulated luminescence process for a measuring method, and the DIS dosemeter containing an MOSFET type analogue EEPROM. These dosemeters have 10 to 100 times lower detection limit than the old film badge.
Then some trials have been conducted to use these dosemeters for measuring environmental doses. Here I will present the technical specifications like detection principles of these dosemeters and some examples of data obtained from application to the environmental dose measurement.
