“…These gases originate from primordial radionuclides ( 238 U and 232 Th), which are present in most terrestrial material and can attain very high concentrations in certain igneous and sedimentary rock. In areas with higher natural background radiation there is thus an additional risk of exposure to radioactive gases (Aliyu and Ramli, 2015;Sohrabi, 2013). Mining activities in such bedrock are associated with radiological issues.…”

“…The dilemma faced by public, governments and international radiation protection community on radiation health effects and risk of low doses has lead to the studies in the high background natural radiation area. Since the low level exposures may bring a stochastic effects to the public, the study of background radiation is extremely vital [1].…”

Abstract. Monitoring terrestial gamma radiation is crucial to prepare a baseline data for environmental radiological protection. Radiological research was carried out in Lahad Datu, Sabah to obtain the radioactivity status and terrestrial gamma radiation level in the area. We measure the terrestrial gamma radiation dose rates and analyse the radioactivity concentration of primordial radionuclides for radiological risk assessment. We identified that the annual estimation of dose effective for public is below the public dose limit, 1 mSv per year. Public and environment safety and health are remain secure. The obtained data and results can be used as reference for environmental radiology protection.

Gama ortam doz eşdeğeri, Gama doz hızı, Yıllık etkin doz eşdeğeri Özet: Çevresel radyasyon düzeylerinin saptanmasına yönelik araştırmalar, halk sağlığı açısından oldukça önemlidir. Bu çalışmada, Eylül 2013 ile Ağustos 2014 tarihleri arasında Isparta şehir merkezinde bulunan 12 okulda gerçekleştirilmiş bina içi ve bina dışı gama ortam doz eşdeğeri ölçümlerine ait sonuçlar sunulmaktadır. Ölçümler için seyyar bir Geiger-Müller dedektörü kullanılmıştır. Genel olarak, 200 nSv/saat civarında seyreden bina içi ve bina dışı gama doz eşdeğeri düzeylerinin birbirine yakın sonuçlar verdiği gözlemlenmiştir. Gama ortam doz eşdeğeri ortalamaları kullanılarak havada soğurulan gama doz hızları hesaplanmış ve gama radyasyonu nedeniyle il halkının maruz kalacağı etkin doz eşdeğeri ise 1,11 mSv/yıl olarak bulunmuştur. Çalışma sonuçları, ülke ve dünya ortalamalarıyla karşılaştırılarak tartışılmıştır. Gamma Ambient Dose Equivalent Measurements for Schools in Isparta City CenterKeywords Isparta, School, Gamma ambient dose equivalent, Gamma dose rate, Annual effective dose equivalent Abstract: Studies conducted on determining the environmental radiation levels are very important in terms of public health. In this work, the results of indoor and outdoor gamma ambient dose equivalent measurements, which were performed between the dates September 2013 and August 2014, have been presented for 12 schools located in Isparta city center. A portable Geiger-Muller detector was used for the measurements. In general, it has been observed that indoor and outdoor gamma dose equivalent levels displayed close results to each other with a value around 200 nSv/h. The absorbed gamma dose rate levels in air have been calculated by means of gamma ambient dose equivalent averages, and then the effective dose equivalent received by the inhabitants due to gamma radiation exposure has been found as 1.11 mSv/year. The results of the study have been discussed in a comparison with the country and the world averages.
