The National Atomic Energy Agency (PAA) said in a statement that "there is currently no risk" to the Polish population.
It added that it was "constantly analyzing data from the national radiation monitoring system."
Its statement came after Ukrainian authorities said on Friday that Russian forces had seized the Zaporizhzhia Nuclear Power Plant in their country and that a building within the complex was set ablaze during intense fighting with Ukrainian defenders, according to a report by the Reuters news agency.
Fears of a potential nuclear disaster at the Zaporizhzhia plant, the largest nuclear power plant in Europe, had raised alarm across the region before authorities said the fire, in a building identified as a training centre, had been extinguished, Reuters reported.
It quoted US Energy Secretary Jennifer Granholm as saying that there was no indication of elevated radiation levels at the plant, which provides more than a fifth of total electricity generated in Ukraine.
