Bazı tütün örneklerinde doğal radyonüklitlerin aktivite konsantrasyonları ve yıllık etkin doz değerleri üzerine bir çalışma

Öz

Tütün örnekleri farklı tütün satış yerlerinden temin edilmiştir. Doğal radyonüklitlerin aktivite konsantrasyonlarını belirlemek için her bir numune 86400 s yüksek saflıkta germanyum (HPGe) dedektörü kullanılarak sayılmıştır. Tütün örnekleri için 226Ra, 232Th ve 40K aktivite konsantrasyonları MDA'dan daha yüksek bulunmuştur. Herhangi bir numunede 137Cs dedekte edilmedi. 226Ra, 232Th and 40K için aktivite konsantrasyonları sırasıyla; 83±15 Bqkg-1ile 325±45 Bqkg-1, 29±5 Bqkg-1 ile 207±37 Bqkg-1 ve (2.09±0.38)x103 Bqkg-1 ile (5.07±0.90) x103 Bqkg-1 aralığındadır. Ek olarak, yıllık etkin doz değerleri hesaplandı. Yetişkinler için soluyarak içine çekmeden dolayı yıllık etkin doz değerleri 214Pb için 2.76 ile 9.91 µSvy-1 aralığında, 214Bi için 5.69 ile 27.69 µSvy-1 aralığında, 228Ac için 5.72 ile 40.41 µSvy-1 aralığında, 40K için 42.23 ile 102.37 µSvy-1 aralığında değişmektedir. Toplam yıllık etkin doz değerleri 0.05 ile 0.16 mSvy-1 aralığında değişmektedir.

A study on the activity concentrations of natural radionuclides and annual effective dose values in some tobacco samples

Abstract

Tobacco samples were collected from different tobacco markets from Antalya in Turkey. To calculate natural radionuclides activity concentration, samples were counted for 86400 seconds by using high purity germanium (HPGe) detector. Activity concentrations of 226Ra, 232Th and 40K for tobacco samples found higher than minimum detectable activity (MDA). 137Cs was not detected in any sample. Activity concentration of 226Ra, 232Th and 40K range from 83±15 Bqkg-1 to 325±45 Bqkg-1, 29±5 Bqkg-1 to 207±37 Bqkg-1 and (2.09±0.28)x103 Bqkg-1 to (5.07±0.90) x103 Bqkg-1, respectively. In addition, annual effective dose value was calculated. The annual effective dose values owing to inhalation for adults change from 2.76 to 9.91 µSvy-1 for 214Pb, from 5.69 to 27.69 µSvy-1 for 214Bi, from 5.72 to 40.41 µSvy-1 for 228Ac, from 42.23 to 102.37 µSvy-1 for 40K. The total annual effective dose values change from 0.05 to 0.16 mSvy-1.
