| Zusammenfassung |
| Our laboratory measured the radionuclide presence in Transylvania region both after
Chernobyl and Fukushima accidents. The paper presents old and new data connected
with these disasters obtained not only by us but also by others laboratories from
Romania. It is an attempt to mark the mainly aspects regarding the radioactive
contamination in our country connected with these catastrophes. After the Chernobyl
accident the radioactive cloud passage over Romania on NE - SW direction brought
relatively intesive radionuclide deposition. On this direction the highest deposition
were found in the areas where this passage during April 30-st and May 1-st were
accompanied by rainfalls. In the rain water and fresh sediment colected at May
1-st, 1986 and measured the next days, all radionuclide species from Chernobyl
could be identified [1]. Additional measurements of 90Sr and 239/240Pu have been
made several years later in different environmental samples (roof sediment, soil,
pollen, sand, roof-water, street dust) collected in 1986 from Cluj-Napoca, Romania
[2].
In the case of Fukushima disaster the air transport from west and north-west
brought small quantities of radionuclides over the Romanian teritorry. Even if in this
case the radioactive cloud was very dilluted, 131I could be clearly identified and
measured in air, rain water and other products as: milk, vegetables, grass, fresh
meat from the NW of Romania [3]. Measurements have been also conducted in
Bucharest and Pitesti. During the last 5 years suplimentary 137Cs measurements were
made in different areas as an attempt to use this radionuclide as soil and sediment
tracer.
