Birçok uygulama ve disiplin alanında kullanılan radyoaktivite ölçümlerinin doğru ve güvenilir olması çok önemlidir. Kalite kontrol, cihaz kalibrasyonu ve geliştirilen radyokimyasal metotların doğruluğu radyoaktif standartlar ve referans malzemeler kullanılarak yapılmaktadır. Radyonüklit metrolojisinde sıvı sintilasyon sayım (SSS) sistemi, özellikle kısa ömürlü radyonüklitlerin standardizasyonuna olanak sağlayan hızlı ve kolay numune hazırlama adımlarına sahip olması nedeniyle sıklıkla tercih edilmektedir. SSS cihazındaki dedektörün sayım verimi TDCR gibi doğrudan ölçüm yöntemiyle veya CIEMAT/NIST yöntemi gibi bir izleyici tekniği kullanılarak hesaplanabilir. Bu nedenlerden dolayı SSS yöntemiyle standardizasyonu yapılan radyonüklitlerin sayısı her geçen gün artmaktadır. Bu çalışmada hazırlanan trityum standart çözeltileri SSS sisteminde sayılmış ve CIEMAT/NIST yöntemi kullanılarak belirsizlik değerleriyle birlikte aktivite konsantrasyonları hesaplanmıştır.

Radioactivity measurements used in many applications and disciplines must be accurate and reliable. Quality control parameters, instrument calibrations, and accuracy of the applied radiochemical methods are performed using traceable radioactive standards and reference materials. The liquid scintillation counting (LSC) system is highly preferred to standardize radionuclides in radionuclide metrology. It has quick and easy sample preparation steps that allow standardization of short-lived radionuclides. Besides, the counting efficiency of the detector in the LSC system can be calculated either by the direct measurement method such as TDCR or by using a tracer technique such as the CIEMAT/NIST method. For these reasons, the number of radionuclides standardized by the LSC method has increased over time. In this study, tritium standard solutions prepared from high activity tritium reference solution were counted in the LSC system. Activity concentration values with the uncertainty were calculated using the CIEMAT/NIST method.
