“…The values of excess life cancer risk, ELCR 70 , obtained for the cement mortars ranged from 0.71 � 10 �3 to 0.82 � 10 �3 with the average value of 0.75 � 10 �3 . Even though the world average value of ELCR for indoor gamma radiation 1.45 � 10 �3 48 was not exceeded, the ELCR value of 0.8 is linked to the risk of developing lung cancer 0.378 per 100,000,000 people in accordance with Mirdoraghi et al 49 Mohammed and Ahmed 48 mentioned also the relationship between the ELCR value and the corresponding increased risk of cancer. According to the study, the ELCR equal to 1 may result in an increased risk of 0.004%.…”

With the ever-increasing trend of incorporation of various wastes into building materials, monitoring the potential rise in the radioactive load due to used waste is needed. This paper presents the results of our investigation into the radioactivity of cement mortars of various percentage of granulated blast furnace slag (GBFS). The calculated gamma indexes, Iγ, reached 0.19–0.22 and thus did not exceed, in case of any sample, the required level (Iγ = 1) for bulk materials. Indoor gamma absorbed dose, D, ranged from 41.08 to 47.80 nGy/h being lower by 47% than the world average ones are. The excess life cancer risk, ELCR70, obtained for the cement mortars ranged from 0.71 × 10−3 to 0.82 × 10−3 with the average value of 0.75 × 10−3. Linear correlation between the GBSF content and ionizing radiation was found for 226Ra radionuclide, while polynomic correlations have been found for the mass activities of 232Th and 40K radionuclides and the GBSF amount in the cement sample. Findings revealed that the overall 226Ra mass activity of the composite could be predicted based on the measurement of the mass activities of the individual input components.

The specific activity of natural radionuclides were measured by gamma ray spectrometry with NaI(Tl) detector in the mining waste soil samples collected from Simberi gold mine in New Ireland province of Papua New Guinea. The isotope concentrations of 238U and 232Th in Simberi soil samples are 10.7 and 41.3 ppm respectively whereas the world average values are 2.64 and 11.1 ppm respectively. The average Radium equivalent activity in Simberi samples is 372.2±81.4 Bq/kg which is observed to be higher than the threshold safe value of 370 Bq/kg. The average internal hazard index for Simberi samples is found to be 1.4 which is higher than the maximum permissible value of 1.0. The Excess Lifetime Cancer Risk (ELCR) is calculated to be 0.00553±0.00122 in Simberi whereas the world average value is 0.00145. Radiation in Simberi is found to be higher which may be because Simberi is situated in the volcanic region of Papua New Guinea

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.
