Monitoring of atmospheric radionuclides is an important part of avoiding or eliminating the risk of diseases to the general
public1 Gross α and gross β activities results should be important in understanding the trends of atmospheric radioactivity and for
the variation in time. Airborne particulate samples were collected monthly during the years 2003 and 2004. Radioactivities
were determined using WPC 9550 α/β counting system. The arithmetic means of gross α/β activities were 202·10−3 and 285·10−3 Bqm−3, respectively. The data obtained in this study provide a base line for evaluating possible future changes.
