ABSTRACT
Alpha and beta activities per unit volume of air, due to radon, thoron and their decay products 鈥巜ere measured in the outdoor atmosphere in Errachidia city, 鈥嶮orocco, by using both CR-39 and LR-115 type II solid-state nuclear track detectors (SSNTDs). Simultaneously, meteorological parameters such as air temperature, atmospheric pressure, and relative humidity were also measured in situ.. In addition, the outdoor radon activities show the highest value of the outdoor radon activity was determined in the early morning hours, and the lowest values were found in the afternoon, over a three month study period, between April-June 2006. The diurnal variations in the 鈥巓utdoor radon activity are found to exhibit correlation with relative humidity and negatively correlate with the air temperature. The annual effective dose in the present study for 鈥嶦rrachidia environment is found to be 0.29 mSv/y.
