“…The observed radium equivalent activity in this study ranged from 53 Bq kg À1 to 378 Bq kg À1 with an average value of 206 ± 71 Bq kg À1 , which is lower than the safety limit set for this index. Our results are comparable to values of 28.65e385.05 Bq kg À1 obtained in Coastal sediments of Tamilnadu , 133-323 Bq kg À1 obtained in the shore sediment of Vizag, India (Tripathi et al, 2013), 45-386 Bq kg À1 obtained in Firtina valley sediments (Kurnaz et al, 2007) and 75.54e393.29 Bq kg À1 obtained in rivers sediments of Northern Pakistan (Qureshi et al, 2014). From the radiological protection point of view, the sediments from Oguta Lake could be used as building materials without any restrictions.…”

“…It is the sum of the weighted activities 226 Ra, 232 Th and 40 K based on the estimation that 10 Bq kg À1 of 226 Ra, 7 Bq kg À1 of 232 Th and 130 Bq kg À1 of 40 K produced the same gamma dose rate (SureshGandhi et al, 2014;Tripathi et al, 2013). In terms of the radiological health safety assessment, the maximum permissible limit of Ra eq 370 Bq kg À1 had been set for materials to be used as component of building construction (Berekta & Matthew, 1985;Sivakumar et al, 2014).…”

SedimentOguta Lake Excess lifetime cancer risk a b s t r a c tThe distributions of naturally occurring radionuclides 226 Ra, 232 Th and 40 K in sediments of Oguta Lake, Nigeria were determined using gamma ray spectrometry in order to assess the radiological health hazards and excess lifetime cancer risks associated with the use of the sediments. The mean activity concentrations of 226 Ra, 232 Th and 40 K were found to be 47.89 ± 18.67 Bq kg À1 , 55.37 ± 32.74 Bq kg À1 and 1023 ± 474 Bq kg À1 , respectively. The results of the radiological indices and dose rates obtained in this study were all higher than their worldwide mean values but lower than their maximum recommended limits indicating that the use of the sediments as building materials do not constitute any excessive radiological hazards. The area is known to be subjected to environmental degradations due to oil exploration. Therefore, the results of this study could serve as an important radiometric baseline data upon which future epidemiological studies and environmental monitoring initiatives could be based.

“…The minimum, maximum and average value of AEDE for Besant Nagar beach sands are 13±4 µSv.y -1 , 26±6 µSv.y -1 and 18±5 µSv.y -1 respectively. The annual effective dose equivalent values obtained for other Indian coastal regions are: 2360 µSv.y -1 in Chhatrapur beach of Orissa [12], 120 µSv.y -1 in Andhra coast [13] and 507 µSv.y -1 in Kerala [14]. All these values are higher than the average value of 17±5 µSv.y -1 and 18±5 µSv.y -1 obtained with the present study for Marina and Besant Nagar beach sand samples respectively.…”

“…Therefore, the radionuclides concentrations and distributions, and its associated dose rates in the beach sands from coastal environments should be monitored. The distribution of primordial radionuclides in coastal sands have been reported by many investigators [3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”

The natural radioactivity content of 238U, 232Th and 40K in the intertidal beach sands samples at ten sites each of Marina and Besant Nagar beaches of Chennai city has been analyzed using a 3"x3" NaI(Tl) scintillation detector based gamma ray spectroscopy. The radioactivity content in intertidal sands of Marina were found to be 4±3 Bq.kg -1 , 4±3 Bq.kg -1 and 248±28 Bq.kg -1 respectively; the same were 4±3 Bq.kg -1 , 5±3 Bq.kg -1 and 242±29 Bq.kg -1 respectively in the beach sands of Besant Nagar. These activity levels at both beaches are, in general, much lower than other Indian and World average value. The radiological parameters for both the intertidal sand samples (Marina and Besant Nagar) are far lower than the UNSCEAR 2000 recommended values.

“…The main pathways of the naturally occurring radionuclide entrance into the marine environment were river transport, rain water, fallout, etc. Moreover, the activity concentration of these radionuclides was reported to be dependent on physicochemical parameters such as organic matter content and pH levels of sediments (Tripathi et al, 2013;Özmen, 2020). A slight decreasing trend of 226 Ra and 232 Th activity levels was reported with the increasing distance from shoreline and depth (coastal zone, max.…”

To evaluate the radiological load of the fisheries ground sediments of deep-water areas in the Antalya Bay, 226 Ra, 232 Th, 40 K and 137 Cs activity concentration levels were measured with the Gamma Spectroscopy technique using a HighResolution Germanium Detector (HPGe). Sediment samples were collected from the seabed surface of five different depth ranges (between 400 -800 m). Detected mean radionuclide activities of 226 Ra, 232 Th, 40 K and 137 Cs were 16.53±2.41, 17.9±2.54, 371.44±18.44 and 3.91±1.27 Bq kg -1 , respectively. The effect of the Chernobyl Nuclear Power Plant disaster in deep water sediments of Antalya Bay was observed. However, the detected radionuclide concentrations are at acceptable levels according to the International Atomic Energy Agency (IAEA).
