“…In this study, ESD measurements were performed experimentally using TLD, while some studies have calculated the ESD value using simulation software due to restricted access to dosimeters (25,26) . Some studies have also calculated ESD with specicformulas from other radiation parameters such as X-ray Output Device (27)(28)(29)(30) . Therefore, one of the possible reasons for the difference in measured dose values can be the difference in the method of ESD determination.…”

The use of ionizing radiation is popular as the most essential human-made source for medical diagnosis in most countries (1) . Medical images should provide enough information to make medical decisions with appropriate accuracy. In many cases, higher quality images are obtained using a high rate of radiation, which increases the dose of radiation received by patients (2) .The potential risk of losing diagnostic information due to a low radiation dose should be balanced

“…Tehran is located at 51º 17' to 51º 33' E and 35º 49' N latitudes, with an area of 733 km 2 . According to the census of 2016 [19], this city is populated by 8693706 people (Figure 1). Tehran is situated in a zone between mountains and deserts, and the surface waters of the Alborz Mountains range are directed to the south.…”

Background: This study aimed to investigate the concentrations of heavy metals bound to airborne Particulate Matter (PM) in high-traffic districts of Tehran, Iran, and to determine the carcinogenic risk and Hazard Quotient (HQ) of these metals using a descriptive-applied method. Methods: Six indoor/outdoor stations were established in three high-traffic districts of Tehran. Each station was sampled with six replicates in winter 2018 (36 samples in total). After extracting the metals from fiberglass filters by acid digestion based on the ASTM (the American Society for Testing and Materials method), the concentrations of heavy metals were determined by an Inductively Coupled Plasma (ICP-OES) device. The human health risk was evaluated according to the US EPA (Environmental Protection Agency) standard method. The obtained data were analyzed by the Spearman correlation and Multivariate Analysis of Variance (MANOVA) in SPSS. Results: Districts 2, 3, and then 15 were the most high-traffic areas of Tehran in descending order. Average heavy metal concentrations were detected in order of Al>Fe>Pb>Mn>Cu>Zn>Cr>As>Ni>Cd. Also, the heavy metals concentrations were significantly different between indoor and outdoor environments. The correlations between heavy metal concentrations, carcinogenic risk, and HQ were significant in all three districts (P<0.05). Mean carcinogenic risk variables, HQ levels, and heavy metal concentrations in all three regions were in order of districts 15>2>3 and outdoors>indoors. Conclusion: Based on the results, serious measures are recommended to control traffic congestion in Tehran to prevent cancer risk and other health hazards caused by heavy metal bonded TSP (total suspended particulate matter).

The aim of the data was to measure the absorbed dose of gamma radiation in order to estimate the excessive risk of cancer-induced gamma radiation during the lifetime of Bojnurd residents. In this descriptive cross-sectional study, gamma radiations in 30 places was measured in Bojnurd City during four seasons in 2015. A dosimeter was stacked on a tripod at 1 m from the ground for 50 minutes, and then, the absorbed dose of gamma radiation was recorded in the checklist. Ultimately, the effective dose and the excessive lifetime risk of cancer were determined. The mean ± SE of absorbed dose of gamma radiation in spring, summer, autumn, winter was 134.25 ± 1.45; 139.89 ± 1.64; 134.40 ± 1.25; 143.80 ± 1.73 nGy, respectively. The average annual effective dose by residents in open space was estimated at an average of 0.167 mSv. Also, the excessive risk of cancer-induced gamma radiation was equal to 0.67 × 10−3. The annual effective dose and the excessive risk of cancer-induced gamma radiation during the lifetime of Bojnurd residents are higher than the global average.
