Farklı Çalışma Ortamlarında Gama Doz Hızı Ölçümleri ve Radyolojik Tehlikelerin Değerlendirmesi

Öz

İnsanlar zamanlarının çoğunu evlerinden sonra işyerlerinde ve okullarda geçirmektedirler. Çalışma alanları kapalı veya açık alanları kapsayabilir. Ege Üniversitesi yerleşkesinde akademik ve idari personel, öğrenciler, hastalar ve ziyaretçiler gün içerisinde uzun süreler boyunca çeşitli çalışma ortamlarında bulunmaktadırlar. Bu çalışmada, altı aylık süre boyunca Ege Üniversitesi yerleşkesinde 17'si açık ve 13'ü kapalı olmak üzere toplam 30 noktada taşınabilir radyasyon doz hızı ve doz ölçer cihazı ile gama doz hızları ölçülmüştür. Bu ölçümlerden soğurulan doz oranları, yıllık etkin eşdeğer doz oranları ve yaşam boyu kanser riski hesaplanmıştır. Sonuçlar dünyada ve Türkiye'de yapılan diğer çalışmaların sonuçları ve iş sağlığı ve güvenliği yönetmeliklerindeki sınır değerler ile karşılaştırılmıştır. Sonuçların iş sağlığı ve güvenliği açısından uygunluğu değerlendirilmiştir.

Anahtar Kelimeler

• Gama ışınları
• Kanser riski
• İş sağlığı ve güvenliği
• Gama doz hızı.

Measurements of Gamma Dose Rate in Various Working Environments and Assessment of Radiological Hazards

Öz

People spend most of their time in offices and schools after their homes. Workplaces can include both indoor and outdoor areas. On the Ege University campus, academic and administrative staff, students, patients and visitors occupy a variety of working environments for long periods throughout the day. In this study, gamma dose rates were measured using a portable radiation dose rate and dose meter device at a total of 30 locations (17 outdoors and 13 indoors) on the Ege University campus over a six-month period. The absorbed dose rates, the annual effective equivalent doses and the excess lifetime cancer risk were calculated from these measurements. The results were compared with the limit values established by global studies and other research conducted in Türkiye, and occupational health and safety regulations. The suitability of the findings in terms of occupational health and safety has been evaluated.

Anahtar Kelimeler

• Gamma rays
• Cancer risk
• Occupational health and safety
• Gamma dose rate.
