“…Average absorbed dose rates for all samples are lower than the world average value of 55 nGy/h [7], except for M14 sample. Studies indicate an average outdoor terrestrial gamma dose rate of 60 nGy/h in the world ranging from 10 to 200 nGy/h [18]. From the present work we found that the average terrestrial gamma dose rate is 35.88 nGy/h which is lower than the world average.…”

Fourteen samples of marble were collected from different factories in Egypt. The samples were crushed, dried in controlled furnace for around twenty four hours, and then stored for five weeks in plastic Marinelli beakers. Concentrations and the U-and Th-bearing minerals were studied by scanning electron microscopy (SEM) and energy dispersive X-ray spectrometry (EDS).The gamma radiation of the samples was measured, employing high resolution γ-ray spectroscopy with an accumulating time for about 80000 sec. each. From the measured γ-ray spectra, activity concentrations were determined for marble samples 226 Ra (37. 6 ± 1.7 -100.54 ± 3.2 Bq/kg), All obtained results referred to the fact that all the concentrations were within the allowed limits to domestic use. Comparing the results in this work with those published by International Atomic Energy Agency and local and universal researches, it was found that these concentrations were within the allowed limits for agricultural and domestic uses.

“…It has been found to be about 0.51 times and 0.92 times for Magurchhera and 0.50 times and 0.89 times for Haripur than the worldwide value [4] ( Table 3) and world average [12] (Table 3) values respectively. The mean specific radioactivity level of 40 K in the soil samples has been found to be higher than those of the regional study [22], Ireland [31], Hungary [30], Egypt [23], but the activity concentration of 40 K has been found to be lower than those of the Turkey [17], Kirklareli [18], Spain [16], French rivers-1 [19], French rivers-2 [20], Iran [21], Southern Districts of Bangladesh [27], Kestanbol [24], China [15], South Cameroon [25], Northern Districts of Bangladesh [7], and India [26] (Table 2). The specific activity of 40 K has been found to be about 1.02 times and 1.15 times higher for Magurchhera area than the worldwide value [4] (Table 3) and world average [12] (Table 3) value respectively; similar results have also been found for Haripur area.…”

“…The mean activity concentration of 232 Th in the these gas well areas has been found to be higher than those of the Turkey [17], Kirklareli [18], Ireland [31], Louisiana-USA [29], French rivers-1 [19], French rivers-2 [20], China [15] and Hungary [30],. It is about to 1.6 times and 2.11 times higher for Magurchhara and 1.74 times and 2.29 times higher for Haripur area than the worldwide value [4] (Table 3) and world average [12] (Table 3) respectively.…”

The main goal of this study is to carry out the public exposure contribution from radioactive materials occurring due to the accident of natural gas exploration well of Sylhet division in Bangladesh. This study has been performed by using a gamma spectrometry of Genie 2000 software embedded PC-based High Purity Germanium (HPGe) detector system. The measured activity concentrations of naturally occurring radionuclides 232 Th, 226 Ra, and 40 K have been in the public safety limit on the environment of the study areas. The specific activity of detected anthropogenic radionuclide 137 Cs has been found to be very little with a mean value of 1.65 ± 0.61 and 1.13 ± 0.57 Bq·kg -1 in the Magurchhera and Haripur gas field area respectively.

Effective dose rate evaluation from natural gamma radiation in the region of Ribeirao Preto, SP-Brazil

et al. 2011

Abstract. Assessments of natural gamma radiation were done for urban sites in the city of Ribeirão Preto -SP -Brazil, allowing to infer the average annual effective dose value for the population in these areas. The measurements were done using a vehicle with a mobile radioactivity measurement system, Eberline, with a plastic scintillation detector and a Global Position System (GPS), to collect measurements of gamma dose rate and its spatial distribution. Using the national census information, the stored data allowed mapping the radiometric measurements through the ArcGIS software, correlating the geographical coordinates with their respective dose rates. These maps illustrate how effective dose values are distributed within the selected areas and also correlate the collective dose values for these populations. Around 45,000 georeferenced effective dose values, ranging from 12.2 up to 59.8 nSv/h raised an average value of 0.034 ± 0.004 mSv/year, which is less than the worldwide average effective dose value of 0.07 mSv/year [12] (for outdoor exposures from terrestrial radiation sources) and less than the previous average values found in Brazil for the regions of Poços de Caldas, Guarapari, Andradas, Caldas and Meaípe [2,10].
