“…A comparison of gross alpha and gross beta radioactivities in water samples of Bangladesh with different countries around the world is given in Table 5. Comparing the values of gross alpha and gross beta activities with others, it is observed that gross alpha and gross beta activities of surface water samples in Bangladesh are lower than surface, underground and drinking water samples of other countries of the world like Nigeria, Turkey, India and Brazil [5,6,15]. It is also observed that the gross alpha and gross beta activities in surface water samples in Bangladesh are lower than the tap and bottled water samples of Bangladesh.…”

The main objective of this study is to determine the Gross alpha and gross beta radioactivity in environmental sample. Thirty samples of soil, water and vegetable were randomly collected from the different locations of Bheramara and Ishwardi near the proposed Rooppur Nuclear Power Plant area, Kushtia and Pabna, Bangladesh. The Gross Alpha activity under investigation ranges from 1.13 to 5.66 Bq kg -1 with an average of 2.78±0.16 Bq kg -1 for soil sample, 0.45 to 1.36 mBq L -1 with an average of 0.91± 0.18 mBq L -1 for water sample, and 0.23 to 1.81 Bq kg -1 with an average of 1.0 ±0.11 Bq kg -1 for vegetable sample. The Gross Beta activity under investigation ranges from 30.74 to 132 Bq kg -1 with an average of 71.85±1.99 Bq kg -1 for soil sample, 61.49 to 279 mBq L -1 with an average of 175 ±4.02 mBq L -1 for water sample, and 305 to 1676 Bq kg -1 with an average of 930 ±3.27 Bq kg -1 for vegetable sample. This study will help to prepare baseline data for gross alpha and gross beta radioactivity in environmental sample which will be used as finger print for the comparison of radioactivity level. .

“…The radioactivity in groundwater occurs mainly from radionuclides of the natural decay chains of 238 U, 232 Th and 40 K. Some radionuclides can be easily dissolved in water depending on mineralogical and geochemical composition of soil and rock, redox condition and residence time of groundwater transporting through soil and bedrock, and reaction of groundwater with soil and bedrock [2]. When the decayed radionuclides are taken into human body through ingestion or inhalation, radionuclides will cause internal exposure [3].…”

This research aims to study the specific activity of natural radioactivity in groundwater samples taken in the area of Phra Nakhon Si Ayutthaya Province, Thailand. Totally, sixty groundwater samples collected from wells in eight districts were monitored and determined for radionuclides 226Ra, 232Th and 40K and gross alpha and beta were determined using high resolution gamma spectrometer and Canberra Tennelec Series 5 gas flow proportional counter, respectively. Most of the sixty wells serve for water consumption and some other wells for agricultural. The results showed that the average activity concentrations of the gross alpha and beta were 0.01±0.007 and 0.15±0.02 Bq L-1 and the specific activity of 226Ra, 232Th and 40K were averagely 0.77±0.13, 1.03±0.19 and 15.56±1.28 Bq L-1, and respectively. The activity concentrations of the gross alpha and beta and the specific activity of the radionuclides in these samples exhibited quite low as compared to the recommended reference level for human consumption reported by World Health Organization (WHO).
