Contamination from the Chernobyl fires has not penetrated the atmosphere above Slovakia.
"The level of radiation in the air is on the level of long-term natural background with no elevation at all stations," said Terézia Melicherová, specialist for the national monitoring of the Slovak Hydrometeorological Institute (SHMÚ) for the TASR newswire.
The SHMÚ is monitoring the situation cautiously in ten-minute measurements.
