“…In this research indoor radon concentration in 45% of the basements, 35% of the ground *loors and 5% (only one sample) of the *irst *loors was above the WHO reference level (100 Bq m -3 ) and all of the samples from second and upper *loors were lower than 100 Bq m -3 . Higher concentration of indoor radon in lower *loors has been reported by other researchers as well (27,41,42) Direct contact with soil, plays an important role in increasing indoor radon concentration, because of the exhalation rate of radon from the *loors, which depends on subsoil characteristics (43) .…”

Background: Inhala on of radon and its short-lived decay products is one of the most significant sources of exposure to natural radia on. Radon is the second cause of lung cancer in the popula ons. The present study was carried out under the projects of na onal radon, with the aim of determining the concentra on of indoor in the city of Qom located in the central semi-arid region of Iran. Materials and Methods: Radon measurements were carried out in 123 dwellings using passive sampling with CR-39 detectors for 90 days. The map of radon concentra on distribu on was prepared using Arc GIS so+ware and the sta s cal analysis was performed with SPSS version 20. , respec vely. Conclusion: A correla on was found between the distances from fault zones and measured indoor radon concentra on. In most of cases, radon values were lower in well-ven lated dwellings in comparison with poorly-ven lated ones. Moreover, high radon concentra on levels were observed in basements. The results indicated that in 30 places (24.3% of cases), the radon concentra ons were higher than the reference levels recommended by the World Health Organiza on (100 Bq m -3 ).

“…The CR-39 detectors were placed in a plastic container which permits radon to diffuse in (27) . Detectors were numbered and placed in the selected dwellings according to the U.S. EPA protocol, for 90 days to prevent monitoring from being affected by seasonal changes in the area.…”

“…It was expected, since earlier studies about impact of floor level on radon concentration confirmed that radon concentrations in mult i-story building were higher in basement, i.e. ground level (Chao et al, 1997;Kurnaz et al, 2011;Popovic & Todorovic, 2006 Bq/ m 3 in bedroom of prefabricated ground-floor house built 10 years ago. This is very rarely type of house in Kosovo and Metohija, and because of that it was very interesting for su rvey.…”

“…Major contribution to public exposure relate to inhalation of radon and thoron (UNSCEA R, 2008). Th is is because people spend more time indoors in homes or workplaces (about 80%); that's the way to radon inhalation, and hence increasing the potential risk to lung cancer (UNSCEA R, 1993;ICRP, 1993;Darby et al, 2005;WHO, 2009) (Kurnaz et al, 2011;Alghamdi & Aleis sa, 2014). Seasonal variation of radon indoors affects several parameters: the object, the source of radon, household habits, air ventilation and heating.…”

This paper presents an analysis of indoor radon measurements carried out in municipality of Zubin Potok, northwestern part of Kosovo and Metohija. Annual measurements in two rooms of each house were performed by solid state nuclear track detectors commercially known as Gammadata. Average indoor ra don concentration in di fferent type of houses varied from 29-326 Bq/ m 3 . A di fferent year of house's constructi on i ncluding vari ous types of buil ding materials were selected for survey. A detail analysis showed that the di fferences in radon concentration occur between various buildi ng materi als used for construction, flooring level, type of room and behavior of inhabi tants. It was found that buil ding materials in some houses contri bute addi tionally to indoor radon.

“…Trabzon'da ise evlerde ve okullarda radon gazı seviyesi ölçümleri pasif radon dedektörü kullanılarak yapılmıştır [21][22] Radon, uranyum serisinin bozunma zincirinde bulunduğundan dolayı binanın altındaki toprağın uranyum miktarı, binalarda radon gazı seviyesinin değeri ile ilişkilidir. Radon gazının binaya girişinin temel nedeni, binanın temelinin altındaki toprak ile bina arasında oluşan sıcaklık ve basınç farkından dolayı oluşan gaz akışıdır.…”

Öz Bu çalışmada KTÜ Kanuni Kampüsü'nde ofislerde radon gazı seviyesi ölçülmüş ve çalışanlar için radondan kaynaklanan doz eşdeğerleri tahmin edilmiştir. Radon gazı ölçümleri 30 ofiste yapılmıştır. Ölçümler üçer katlı on binanın her bir katında yapılmış ve katlara göre radon gazı değerleri karşılaştırılmıştır. Çalışanlar zamanının çoğunu ofislerinde geçirdikleri için ofislerde radon gazı ölçümü önemlidir. Radon gazı ölçümleri ALPHAGUARD PQ 2000 radon monitörü ile ölçülmüş, sonuçlar uluslararası değerler ile karşılaştırılmıştır. KTÜ Kanuni Kampüsünde ölçülen radon gazı değerleri izin verilen limit değerlerin altındadır. Ayrıca seçilen bu 10 binanın etrafından alınan toprak örneklerinde radyonüklid analizi yapılmış ve değerler uluslararası kuruluşların izin verdiği limit seviyelerle karşılaştırılmıştır.
