This paper reports the results obtained for outdoor gamma dose rates in Cahul town, Republic of Moldova, in the frame of the project MIS ETC 1676. 50 measurements were carried out in each of the 20 selected locations in April 2015. The obtained average value of ambiental gamma dose rate was 105.3 ± 16.2 nGy/h, with a minimum value of 66.9 nGy/h, and a maximum value of 142.6 nGy/h. The results were compared with the official reports for external gamma dose and with the respective annual average values in Moldova, our results being lower than the attention limit of 250 nGy/h and the average values registered in 2010 and 2011 in the South region of Moldova (130 nGy/h). In all locations, the dose rates values fall in the normal range of variation 52 – 163 nGy/h given in 2008 Report of United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR). The obtained results are an important statistical element for annual evaluation of radioactivity in Moldova and for national reports and will serve as a base in further investigations and preparation of maps of terrestrial gamma dose rates in the frame of the MIS ETC 1676 RO-UA-MD project.
