“…The average dose values obtained in this study (0.76 lSv) were relatively less than the dose values indicated in previously published studies on fish from various parts of the world-2.3 lSv (Pakistan) [1]; 0.82 lSv (Bangladesh) [2]; 36 lSv (South Africa) [7]; 2.0 lSv (Malaysia) [9]; and 0.8 lSv (Canada) [10].…”

“…Previously published studies on different kinds' of fish species from various parts of the world specified the presence of natural isotopes of 226 Ra, 228 Ra, and 40 K in fish [1,2,[7][8][9]. Also, a study with an emphasis in understanding the impact of Fukushima nuclear plant incident on marine environment (West coast of Canada), indicated the presence of man-made isotopes of 134 Cs and 137 Cs in fish samples [10].…”

To understand the contribution of radiation dose to human from consumption of catfish, a comparative radiological assessment study was performed on farm and river raised fish. Gamma spectroscopic analyses of catfish indicated the presence of isotopes of 40 K, 226 Ra, and 228 Ra with activity values of 99.4 ± 14.5, 0.41 ± 0.05, and 0.89 ± 0.08 Bq kg -1 respectively in farm catfish and 101 ± 15.7, 0.47 ± 0.05, and 0.97 ± 0.050 Bq kg -1 respectively in river catfish. The measured activities in two sets of samples were statistically compared using a twotailed t test at 95 % confidence interval and results indicated that activities of 226 Ra and 228 Ra were significantly different.

“…The daily intake of radioactivity is considered to be an accumulation of both naturally occurring radionuclides ( 226 Ra, 232 Th and 40 K) and artificial radionuclide 137 Cs into the human body via the consumption of food. The daily intake of natural and artificial radionuclides via the consumption of food has been calculated using Equation 3 [25]: …where D int is the daily intake of radionuclides (Bq d -1 ) by individuals, A c is the activity concentration of radionuclides (Bq kg -1 ), A ig is the per capita per year consumption of honey, and Y d is the days in a year. Honey consumption rate for the year 2016 was 1.3 kg per person in Kosovo [26].…”

“…Daripada rajah ini didapati kepekatan aktiviti tertinggi radionuklid 226 40 K pula, didapati sampel yang berasal daripada sumber asas haiwan (terutama ikan) merekodkan nilai kepekatan aktiviti lebih tinggi berbanding sumber yang berasal daripada tumbuhan. Tingginya kepekatan aktiviti pada ikan ini mungkin disebabkan oleh pencemaran lautan yang semakin meningkat kerana perkembangan industri yang semakin pesat di negara ini (Khandaker et al 2013).…”
