Abstract Natural radiation is a feature of the environment in which we live. One of the contributions of human exposure to ionizing radiation due to natural sources arises from gamma radiation. Therefore, present study was aimed to evaluate and map indoor gamma dose rate in Tehran. The corresponding annual effective dose (AED) and excess lifetime cancer risk (ELCR) were also calculated. All measurements were performed by a Geiger Muller detector in 43 dwellings in Tehran. The average indoor gamma dose rate in Tehran was appointed as 343.2 nGy/h. AED and ELCR were calculated as 2.4 mSv and 10.3 × 10−3, respectively. The evaluated indoor gamma dose rate and calculated AEDs and lifetime cancer risk were found higher than the world average value.

The annual arithmetic mean concentrations of benzene and 1, 3-butadiene were gradually decreasing tendency from the year 2008 2011 at every monitoring stations in Bangkok. Dramatically decreasing of these air toxics, measured in the road curbside areas were found in the year 2012 when the Thais government implemented the improvement of fuel quality from Euro 2 to Euro 4 standards. Calculated cancer risk of benzene and 1, 3-butadiene dramatically decreased at every monitoring stations. The results indicated that the population was estimated to receive an excess lifetime cancer risk greater than 1 x 10-5, which is proposed as the permissible maximum value for individual excess lifetime cancer risk by the Japan Environmental Agency (JEA). However, cancer risk from air toxic was found significantly decreased in the year 2012. These finding elucidated the effectiveness of changing of fuel quality to the reduction of airborne air toxic concentration in Bangkok environment.
