Abstract

Bu çalışmada, Türkiye'nin Doğu Anadolu
Bölgesi'nde yaygın olarak kullanılan altı farklı gübre çeşidindeki ²²⁶Ra,
²³²Th ve ⁴⁰K radyonüklidlerin spesifik aktiviteleri, NaI
(Tl) gama ışını spektrometre sistemi ile ölçülmüştür. Ölçüm sonuçları, çeşitli
gübre örneklerdeki ²²⁶Ra, ²³²Th ve ⁴⁰K için spesifik
aktivitelerin ortalamalarının (aralıklarının) sırasıyla 19.6 (3.9 - 32.9), 30.3
(11.4-39.9) ve 664.6 (42.6 - 3481.8) Bq kg^-1 olduğunu göstermiştir. Türkiye'de
kullanılan gübrelerde ölçülen doğal radyonüklidlerin ortalama değerleri, diğer
bazı ülkelerde bildirilen değerler arasındadır. Bu çalışma, kimyasal gübrelerin
düzenli tarımsal kullanımına bağlı olarak, halkın radyasyona maruz kalma
seviyesinin belirlenmesi için temel veriler olarak faydalı olabilir.

Determination of Natural Radioactivity Concentrations of Some Fertilizers Used in Eastern Anatolia of Turkey

Abstract

In the
present work, the specific activities of ²²⁶Ra, ²³²Th and
⁴⁰K radionuclides in six different kinds of commonly used
fertilizers in Eastern Anatolia of Turkey were measured by NaI(Tl) gamma-ray
spectrometry system. The results of measurements showed that the mean (ranges)
of specific activities for ²²⁶Ra, ²³²Th and ⁴⁰K
in several fertilizers samples are 19.6 (3.9 - 32.9), 30.3 (11.4- 39.9) and
664.6 (42.6 - 3481.8) Bq kg^-1, respectively. Average values of the
natural radionuclides measured in the fertilizers used in Turkey are within the
range of values reported in several other countries. This study may be useful
as basic data for determining the level of radiation exposure of the population
due to the regular agricultural use of chemical
fertilizers.
