Thermoluminescence properties of unique Rosso Levanto marble.

This marble extracted from deposits in Elazığ in Turkey resembles red meat in appearance and is only found in Elazığ. This type of marble has been widely used in the most famous architectural structures and buildings. In this study, the thermoluminescence (TL) properties of a unique marble that originated from Turkey, named Rosso Levanto, were investigated. Two distinct TL peaks were observed at 160°C and around 375°C. Particle size experiments showed that best TL intensity was seen at 200 μm particle size and therefore dose-response, heating rate, cycle of measurement and fading experiments were carried out on powdered samples with a particle size of 200 μm. The findings revealed good linearity in dose-response, observed up to 0.5 kGy. The reproducibility experiment gave good results, but peak intensity decreased by about 40% in first 6 h of storage in a dark room.
