Abstract

In this study, fly ash and bottom ash which are generated in
Yatagan coal-fired thermal power plant in Mugla, Turkey and coal samples were
analyzed by Canberra HPGe (high-purity Germanium detector) gamma ray
spectrometry to determine the activity concentration of natural radionuclides
such as 238U, 226Ra, 232Th, 40K and
210Pb. Fly ash samples were collected at a total of 5 points along
the emission control system of the thermal power plant, namely: the water
pre-heater, (economizer), air preheater (LUVO) and the three rows of the
electrostatic precipitators (ESP). Triplicate samples were collected from the
same point, thus resulting in a total of 24 samples (coal, bottom ash and fly
ash). The amount of collected samples was around 1 kg from each sampling point.
The range of the activity concentrations obtained in this study were between
155±12 - 451±20 Bq kg-1 for 238U, 187±7 - 563±20 Bq kg-1
for 226Ra, 65±3 - 136±5 Bq kg-1 for 232Th,
305±18 - 831±29 Bq kg-1 for 40K and 186±20 - 1153±44 Bq
kg-1 for 210Pb. In this study, the activity index was
calculated and the lowest activity index was found in the ash sample taken from
water pre-heater point with a value of 2.37. If the building materials were to
be prepared from the ash samples which were taken in this study at a proportion
below 40%, the radiological issues can be ignored in terms of external gamma
radiation.

Abstract

Çalışmada, Yatağan kömür yakıtlı termik santralinden alınan
kömür ve çeşitli uçucu kül fraksiyonlarında
238U, 226Ra, 232Th,
40K ve 210Pb konsantrasyonları Canberra HPGe (yüksek
saflıklı Germanyum dedektörü) gama spektrometresi ile belirlenmiştir. Uçucu kül
örnekleri su ön ısıtıcı, hava ön ısıtıcı ve elektrostatik filtreler olmak üzere
termik santralin emisyon kontrol sistemi boyunca toplam 5 farklı noktadan
toplanmıştır. Aynı noktadan 3 örnek alınmış, böylece toplam 24 örnek (kömür,
dip külü ve uçucu kül) elde edilmiştir. Her örnekleme noktasından toplanan
örnek miktarı yaklaşık 1 kg’dır. Çalışma kapsamında elde edilen aktivite
konsantrasyonlarının
238U için 155±12 - 451±20 Bq kg-1, 226Ra
için 187±7 - 563±20 Bq kg
-1, 232Th için 65±3 - 136±5 Bq
kg
-1, 40K için 305±18 - 831±29 Bq kg-1 ve 210Pb
için 186±20 - 1153±44 Bq kg
-1 arasında değiştiği bulunmuştur.
Çalışmada aktivite indeksleri hesaplanmış olup, en düşük aktivite indeksi 2,37
değeri ile su ön ısıtıcı noktasından alınan kül örneklerinde bulunmuştur. Bina
materyali olarak bu çalışma kapsamında alınan uçucu kül örnekleri %40’ın
altında kullanılırsa, radyolojik sorunlar dış gama radyasyonu açısından göz
ardı edilebilir.

ayrı ayrı hesaplanmıştır. En düşük aktivite indeksi, su ön ısıtıcı noktasından
