Luminescence measurement systems located at the laboratory can be used for both Thermoluminescence (TL), Optically Stimulated luminescence (OSL) and Radioluminescence (RL) measurements. Luminescence from natural and artificial materials can be read and characterised for personal dosimeter, geological and archaeological dating purposes. Furthermore, the systems can be used to study the defect structures and involving TL/OSL mechanism in solids by the investigating their luminescence emissions after UV, X-ray and beta irradiations.

Basic components of systems at the laboratory are;

• Bausch and Lomb monochrometer

• PM tubes with cooled housing

• Edwards rotary and diffusion pumps

• Harshaw 3500 TLD Reader

• Temperature controller unit

• Band pass, cut off and heat absorbent filters, light sources

• Various TL dosimeters (LiF, CaSO4, Al2O3 etc.)

• Memmert Oven

• Analytical balance

• Fume hood

• Various analytical sieves

      

 Natural and artificial radioactivity analyses are conducted in industrial, environmental and food samples. Radioactivity reports may be provided on request for the samples from Izmir and its vicinity.

Distributions of the natural and artificial radionuclides originating from the terrestrial and aquatic ecosystems are investigated by gamma and alpha spectrometers, and atmospheric fluxes of natural radionuclides are observed periodically in the laboratory. In addition, soil-erosion rate, dating sediments, monitoring environmental radioactivity using bio-indicators and developing nuclear spectroscopic techniques are the other study area of the laboratory.
