Abstract
Purpose: This paper presents indoor radon concentrations, impact factors
and
potential
sources
in
29
schools in
the
Eastern
part
of
Republic
of
Macedonia.
Argument: The radon concentrations were measured with nuclear track
detectors exposed in two ground floor rooms of each school in period
of one school year semester starting from January and to June in 2016.
The radon concentrations in 3 of 56 rooms exceed the National action
level. The geometric mean value of measured radon concentrations for
all rooms was 96 Bq/m3; GSD=2.47. There was no correlation between
radon and location altitude. Also, no effect of type of room and type of
windows on radon concentration was found. Ground floor buildings and
buildings with one floor had higher radon concentrations, than buildings
with two floors. The radon concentration in building without basement
was higher than that in buildings with basement, as well as higher in
stone buildings than brick buildings. Relation between radon concentration
and
lithostratigrafic
units
was
confirmed.
The
highest
radon
concentration
was obtained on locations with andesite and breccia bed rock.
Conclusion: The impact level of each of the examined factors on radon
variations were quantified by a determination factor (R2) The highest R2
value was related with factor: basement. Тhe individual factor effect
on radon variation as well as explanations of the obtained results are
discussed in this paper
