Abstract:The aim of this paper is to identify potential exposure of the workers in the coal mine Tusnica. The results of the investigation showed increased activity of brown coal up to 106088 Bq kg1 for 238U, 97630 Bq kg1 for 226Ra and 11831 Bq kg1 for 232Th. Dose rate measurements ranged from 0.07 to 0.25 Sv h1. The annual effective dose, taking into account external exposure to ambient gamma radiation and internal exposure due to inhalation of the resuspended dust, would be 1.6 mSv a1. The results presented lead to the conclusion that Tusnica coal mine contains brown coal with significant radioactivity, indicating that the working hours in the area should be regulated and the use of respiratory protective equipment is obligatory.
