Hidayet Karakurt
Independent Researcher, Soil and Ecology Department of Poplar Research Institute, Chairman of Department
His present institution is Poplar and Fast Growing Tree Species Research Institute in Izmit, Kocaeli, Turkey. He is working here as Head of Department of Soils and Ecology Studies.
He is interested in mainly forest ecology, silviculture, degraded ecosystems by mining and restoration ecology, forest health and ecosystem monitoring. He has recently participated a research project on determination artificial radioactivity in the forest ecosystems as a coworker. He wants to begin new projects on various subjects like ecosystem studies and rehabilitation of mined sites.

and 232Th isotopes in forest soils was investigated by
using gamma-ray spectrometry. An extensive
radioecological study was carried out between 2010
and 2013 in Mount IDA/Kazdagi, located in Edremit
region in Turkey. A total of 341 soil samples were
collected from the surface and organic horizons (OL,
OF+OH, and A) in 118 soil profiles. The distributions of
natural radioactivity levels in these horizons and corresponding
absorbed dose rates from outdoors terrestrial
gamma radiation throughout the region were mapped in
detail. Mean 40K activity values over the combined horizons
varied between 43 and 1,008 Bq kg−1; whereas,
mean 226Ra and 232Th concentrations over the combined
horizons ranged between 5–152 and 6–275 Bq kg−1,
respectively. Our data indicate that the radioactivity
values of the study sites were within the universal normal
range. The significant variation among the 232Th, 226Ra,
and 40K activities and gamma dose rate might be due to
the geological variation in the study sites.
Mount IDA (Kazdagi)/Edremit, Turkey. For 118 soil profiles, the depth distribution of 137Cs activity was
established by fitting the experimental points to an exponential, a gaussian or a log-normal function. The
relaxation lengths were in the range of 1.09e16.7 cm with a mean of 5.73 cm, showing a slow transport
and a strong retention capacity of 137Cs even after the 26-y period of Chernobyl accident. From the data
for the vertical distribution of 137Cs in soil profiles, the mean annual migration velocity of 137Cs was in the
range of 0.11e0.62 cm year1 with a mean of 0.30 cm year1. Statistically significant correlations between
the thickness of the humus layer and the mean annual velocity of 137Cs were found for both coniferous
and mixed forest sites. The mean annual velocity of 137Cs in the forests sites with Pinus nigra var pallasiana
was significantly higher than sites with Pinus brutia. External dose-rates from the 137Cs in forest
soils were estimated using a conversion factor used in many studies and comprised with the external
dose-rates determined according to the vertical distribution of 137Cs within the soil depth profiles. It is
clearly seen that both levels and spatial distribution patterns of the external dose-rates from 137Cs were
influenced considerably with the vertical migration rate and the vertical distribution of 137Cs.
