Summary: This paper shows the daily portion of forest cutters´ exposure to total dust or respirable fraction of oakwood during cutting and processing of fuelwood. The separators of non- respirable particle fraction (cyclons) operate in a way similar to the separation of respirable particles in the respiratory system of a healthy adult, with a medium efficiency (50 %) of 5 mm aerodynamic diameter. The mean value of mass concentration of total oak dust was 1.562 ± 0.163 mg/m3 and respirable fraction 0.618 ± 0.223 mg/m3. As the Rules, which classify oak dust as one of carcinogens, is soon to be passed in Croatia, the significance of the results lies in the fact that none of the measured values (N = 8) exceeds the Croatian limit values for mass concentration of hardwood dust recommended for the workplace. However, some dilemmas remain because of the claims of occupational medical experts that any limit value of any carcinogenic substance is not the guarantee against the illness but rather the guideline for providing an adequate level of protection.
