Abstract

İnsanlar genelde zamanlarının %90’dan daha büyük bir kısmını kapalı ortamlarda geçirmektedirler. Kapalı ortamlarda radona maruz kalma sağlık açısından önemli bir problem olabilmektedir. Bu çalışmada Afyon Kocatepe Üniversitesi Ahmet Necdet Sezer Kampüsü’nde 6 fakülte binasında, çalışanların ve öğrencilerin sağlık risklerini değerlendirmek ve yıllık etkin doz eşdeğerlerini hesaplamak için radon konsantrasyonları ölçülmüştür. Ölçümler aktif ölçüm metoduyla ölçüm yapan Genitron marka AlphaGUARD PQ2000 PRO Radon Detektör Sisteminde gerçekleştirilmiştir. Fakülte binalarının radon konsantrasyonu değerleri 4.48-82.00 Bqm-3; ortalama radon konsantrasyonları ise 20.64-30.91 Bqm-3 aralığında belirlenmiştir. Tüm binaların ortalama radon konsantrasyonu 24.79 Bqm-3 olarak hesaplanmıştır. 6 fakülte binasının yıllık etkin doz eşdeğerleri 0.16-0.24 mSvy-1 aralığında belirlenmiş, ortalama yıllık etkin doz eşdeğeri ise 0.20 mSvy-1 olarak hesaplanmıştır. Elde edilen sonuçlar, kapalı ortamlarda radon gazı konsantrasyonları için Uluslararası Radyolojik Koruma Komisyon (ICRP) ve Türkiye Atom Enerjisi Kurumu (TAEK) tarafından tavsiye edilen limit değerlerle karşılaştırılmıştır. ANS Kampüsü’ndeki 6 fakülte binasının radon konsantrasyonlarının ölçüm sonuçları ve yıllık etkin doz eşdeğerleri, kuruluşlar tarafından izin verilen limit değerlerinin altında belirlenmiştir.

Determination of Indoor Radon Concentrations and Annual Effective Dose Equivalents at Afyon Kocatepe University Ahmet Necdet Sezer Campus

Abstract

People generally spend more than 90% of their time indoors. Exposure to radon in indoor environments can be a significant health problem. In this study, radon concentrations were measured to evaluate the health risks of employees and students in 6 faculty buildings in Afyon Kocatepe University Ahmet Necdet Sezer Campus and to calculate annual effective dose equivalents. Measurements were carried out in the Genitron AlphaGUARD PQ2000 PRO Radon Detector System which measures with active measurement method. The radon concentration values of the faculty buildings are 4.48-82.00 Bqm-3; mean radon concentrations were determined in the range of 20.64-30.91 Bqm-3. The average radon concentration of all buildings was calculated as 24.79 Bqm-3. The annual effective dose equivalents of 6 faculty buildings were determined in the range of 0.16-0.24 mSvy-1, and the average annual effective dose equivalent was calculated as 0.20 mSvy-1. The results were compared with the limit values recommended by the International Commission on Radiological Protection (ICRP) and the Turkish Atomic Energy Authority (TAEK) for radon gas concentrations in indoor environments. The measurement results of the radon concentrations and annual effective dose equivalents of the 6 faculty buildings on the ANS Campus were determined below the limit values allowed by the institutions.
