The Copper Mill Sevojno produces various copper and copper alloy products for utilization in different industry sectors. Technological process of copper rolling from blocks to strips consists of cold and hot rolling. For the control of copper strip thickness radio-isotope strip thickness gauges are installed. These gauges are widely used for contactless measurement of the metallic or non-metallic strip thickness. At the Copper Mill Sevojno, radio-isotope strip thickness gauges are with radio-isotope Sr-90. The gauges are placed on the machines for cold rolling of copper and brass strips, named rolling mills. The employees that operate on these rolling mills are exposed to gamma radiation and are under legislation dosimetric control. The results of dosimetric monitoring of rolling mills workers are presented here. The doses, in terms of personal dose equivalent, Hp(10), are reported quarterly, as those workers are categorized as B group workers occupationally exposed to ionizing radiati...on. Measurements are done with thermoluminescent system that consists of Harshaw 6600 Plus automatic reader and thermoluminescent dosimeters for whole body TLD-100 (LiF:Mg,Ti). Annual doses are given for all four groups of monitored twenty-one persons for three-year period. The results show that maximal measured personal annual dose is less than recommended annual dose limit of 20 mSv.
