In
Turkey , a
series of
researches
have been done since the Çernobil accident.This subject is very
important not
only in Turkey, but also in European countries.It was a very bad
experience
for the world.We believe that these kind of studies are very important
for our
safety.
In
soil
samples taken
from the
plantation areas in Tirebolu , Araklı, Sürmene, salarha and
Kirazlık total
radioactivity levels of 134 Cs and 137 Cs were found to be 216, 106,
118, 283
and 415 Bq/kg respectively. At the same plantation areas, in the stems
of the
tea plants, radioactivity levels of cesium were found to be 208,
139 ,
268, 461 and 425 Bq/kg respectively.The least radioactivity levels were
found
in Araklı and the most radioactiviy levels were found in Salaha And
Kirazlık
plantation areas . There is an important correlation between soil and
plant
radio –activity levels of the same plants.The radioactivity levels of
cesium
have been counted to be 132, 248 , 143, 314 ve 369 Bq/kg ,
respectively, in the
old leaves is less than the level in the plant stems.The
radioactivity of
cesium was measured with the old tea leaves that were taken from the
pruned tea
bushes.These results showed that the radioactivity of cesium rates
decreased a
little but this is not important statistically.
In
this study , the tea
leaves were
taken from pruned and unpruned tea bushes.The radioactivity levels of
cesium
were compared between pruned and unpruned tea bushes during the first,
second
and third flush periods.
