This project is a part of the radiological characterization of the Gamma hall and the Radiochemistry laboratory (RKL) at The Svedberg laboratory. Measurements of surface contamination in both premises have been done by taking wipe-test samples from the floors and walls in the two rooms. A 3D model of both premises has been designed in MATLAB. The model shows the distribution of the measurement points and their contamination values on the floors and walls in these premises. Measurements of the surface contamination were done with two different methods. The results of the measurements do not indicate any contamination in the Gamma hall. In the Radiochemistry laboratory small amount of the contamination has been detected mostly on the floor.
