A
t the Institute for Medical Research and Occupational Health in Zagreb, Croatia, research on environmental radioactivity
has been carried out over a number of years. After the Fukushima accident in March of 2011, we have paid a special
attention to its possible impact on the radioactivity of soil and precipitation in Northwest Croatia (Zagreb region). Before and
after the accident, we determined the activity concentrations of
137
Cs (
A
) in soil samples taken from 3 adjacent surface layers
(depths of 0-5 cm, 5-10 cm and 10-15 cm) as well as in samples of milk. Before the accident,
A
in the soil was nearly uniform,
only slightly increasing with increasing depth. Shortly after the accident, we observed an increase of
A
in the topmost layer,
which was in agreement with the values of
A
measured in fallout. In subsequent years, we have detected both the penetration
of
137
Cs deeper into the soil and the overall decrease in
A
. In 2010, the values of
A
in milk were quite uniform over the months,
amounting to about 35 Bqm
-3
. In 2011, this increased to 199 Bqm
-3
in average, mainly due to the large values measured in
the summer months; we attribute this effect to the influx of the radioactive matter from Fukushima. In consequence of the
increased presence of
137
Cs, the estimated yearly effective dose due to the intake of
137
Cs via milk in 2011 was 200 nSv, which
can be compared with 73 nSv in the period of 2010-2015
.
