It stores dose information until heated to over 250 degrees centigrade when it gives out light, the amount of which is proportional to the dose received. It is environmentally robust and excellent for use in both temperate and warmer climates. Two, four, eight and thirteen weekly wear periods are available.
Calendar wear periods are also available where larger quantities of dosemeters are required.
