Radon problem has a special attention in many countries in the world and the most of them have established national radon programmes. The radon issues in Serbia have not been approached in a systematic and organized way. Currently, there are many research groups and institutions working in radon field, and it is a good basis to integrate all these activities into a comprehensive national programme to define the strategic objectives and action plan for the next few years. Also, Serbia as a candidate for membership in the EU is obliged to harmonize its legislation, including the field of radiation protection in which the radon issues has an important role. In this report, a brief history of radon research, present status and plans for the future activity on radon issues in Serbia are presented. Regarding the long-term plans, the establishment and implementation of the Radon Action Plan with the primary goal of raising awareness about the harmful effects of public exposure to radon and implementing a set of measures for its reduction. In that sense, the synergy between the national, regional and local organizations responsible for public health and radiation protection must be achieved.

The concentration of total alpha and radon activities in soil was measured by collecting soil samples at different locations in Jazan. In this study the passive dosimeters which were based on solid state nuclear track detectors SSNTD are reviewed. The principle of passive dosimetry and the factors affecting their performance are discussed. The concentrations of radon and alpha emitters in different locations in Jazan were evaluated using CR-39 detector. The method is based on the proxy equilibrium factor K. The alpha emission distributions in volume and radon concentrations at the top of the shelf of a 9.0 cm height diffusion chamber were determined. The radon concentrations are ranging from 55 to 151 Bq/m 3 with an average of 88 Bq/m 3. The highest dose was measured to be 1.7mSv/y on Cady Mall and the average annual effective dose was 1.42 mSv/y. These values were in the range of allowed international value according to the values of (ICRP 2009). 

This study pres ents the re sults of a sur vey of ra don con cen tra tions in schools (kin der gar tens, pri mary schools, sec ond ary schools, high schools, col leges, and one fac ulty) lo cated in the prov ince of Nevsehir which is the cen ter of the Cappadocia re gion. Ra don mea sure ments covered two con sec u tive 6-month pe ri ods in the ground floor class rooms in side the school buildings and they were per formed us ing a con tin u ous ac tive ra don de tec tor (AlphaGUARD PQ2000 PRO). Data dis tri bu tion is well fit ted by a log-nor mal curve. The arith me tic av er age value of the ra don con cen tra tions mea sured in sum mer and win ter was found as 75 ± 12 Bqm-3 and 67 ± 10 Bqm-3 , re spec tively. From the mea sured re sults, the ef fec tive doses from ra don ex po sures in sum mer and win ter were es ti mated as 0.27 and 0.40 mSv and 0.24 and 0.36 mSv for stu dents and teach ers, re spec tively. The re sults showed that ra don concen tra tion mea sured in schools does not pose sig nif i cant health haz ards for stu dents and teach ers.
