It was well known that inhalation of high levels of radon can lead to lung cancer. Indoor radon concentration measurements were carried out in randomly selected 18 dwellings of Yıldırım county in Bursa, Turkey using Makrofol-DE Solid State Nuclear Track Detectors. The results of the radon measurements ranged from 13 to 98 Bq m^{-3}, with as 42 Bq m^{-3} average value. The range of annual effective dose was between 0.33 and 2.47 mSv y^{-1}.

Usage of marble dust was investigated for soil stabilization in the scope of utilization of waste material. Geotechnical properties, such as compaction, Atterberg limits, unconfined compressive strength of the mixtures and changes of these properties with the marble dust ratio were determined. From the test results it is seen that marble dust increases the mechanical properties of soil and application of dust wastes for soil stabilization will be an efficient practice in terms of solid waste management.

Magnetic nanostructured materials have been found to be very efficient in wastewater decontamination. Among the various synthesis methods, co-precipitation is a rapid and cost-effective technique for the manufacturing of magnetic nanoparticles; moreover, using green chemistry for their stabilization with natural non-toxic capping agents in aqueous solution, such materials become potential candidates as nanocatalytic formulations for water remediation, topic which represents the aim of the present study. Thus, three types of environment-friendly magnetic fluids were synthesized using the chemical precipitation route, the resulted samples being further characterized by various analytical techniques, in order to assess their microstructural features. The results revealed excellent stability in suspension of all samples, the magnetite nanoparticles exhibiting sizes in the nanoscale range with a relatively spherical shape and suitable magnetic properties. Such nanoparticle based products could be the right choice for magnetic responsive and recyclable materials used in the degradation of emerging pollutants from wastewaters.
