Abstract

Radon is a tasteless, odorless,
colorless radioactive noble gas which is produced in the decay chain of
uranium existed in the rock layer. Since
radon is in the gas form, it is more mobile than its parent radionuclides
which namely are uranium and radium. Therefore, radon can easily
escape soil and rocks through the pores between the soil granules, and the
openings in the rock, cracks, and fractures. Because of these characteristics,
changes in radon concentration levels are commonly used for seismological
purposes. The aim of this study is to investigate the relationship between the
radon activity concentration in soil gas on Akşehir fault zone and the vertical
distance of the sampling points to the fault zone. For this purpose, radon
activity concentrations were monthly determined at 10 sampling points during
six-month period. Although no significant correlation can be seen for all
sampling points at all, a correlation coefficient of 0.96 was obtained when
only the six of sampling points taken into account.

Toprak Gazı Radon Konsantrasyon Seviyesi ile Örnekleme Noktasının Akşehir Fay Hattına Uzaklığı Arasındaki İlişki

Abstract

Radon, kaya tabakasında
bulunan uranyumun bozunum zinciri içinde oluşan tatsız, kokusuz, renksiz radyoaktif
bir soy gazdır. Radon gaz halinde olduğu için, uranyum ve radyum olan ana
radyonüklidlerinden daha hareketlidir. Bu yüzden, radon, toprak granülleri
arasındaki gözeneklerden, kayadaki açıklıklar, çatlaklar ve kırıklardan
kaçmasıyla toprağı ve kayaları kolayca terk edebilir. Bu özelliklerden dolayı,
radon konsantrasyon seviyelerindeki değişiklikler genellikle sismolojik amaçlar
için kullanılır. Bu çalışmanın amacı, Akşehir fay hattındaki toprak gazında
radon aktivite konsantrasyonuyla örnekleme noktalarının fay hattına olan dik
uzaklığı arasındaki ilişkiyi incelemektir. Bu amaçla, radon aktivite
konsantrasyonları altı aylık dönemde 10 örnekleme noktasında aylık olarak
belirlenmiştir. Tüm örnekleme noktaları için anlamlı bir korelasyon
görülmemesine rağmen, yalnızca altı örnekleme noktası dikkate alındığında 0.96'lık
bir korelasyon katsayısı elde edilmiştir.
