Outokumpu's melting furnace at Tornio was exposed to a source of radiation during the night between Thursday and Friday which was identified as americium.
The mill security system revealed the radiation source and standard security actions were carried out according to the company processes. Four meltshop employees were exposed to radiation as they entered the melting furnace during maintenance work.
The Finnish Radiation and Nuclear Safety Authority (STUK) said: "Preliminary measurements made by Finnish Radiation and Nuclear Safety Authority (STUK) indicate that one of the employees was potentially exposed to a dose of approximately ten millisieverts of radiation. The dose was limited and does not pose adverse health effects to the employee.
"According to the seven-step International Nuclear Event Scale (INES), such a dose is a level 2 incident - meaning that it is a material safety risk event. The first measurements of the three other employees observed no abnormal radioactivity. This incident didn't pose any hazard to employees outside the meltshop furnace area."
