Abstract In the present paper the different ways of assessing the annual effective dose due to ingestion of radionuclides by drinking water consumption were examined and exemplified. On a set of 10 samples the gross alpha activity, the gross beta activity, the concentration of 210Po, 210Pb, 238U, 232Th and, 226Ra were measured. The highest annual effective dose values assessed by relying on the investigated sample set were found by using the rationale according to which all the gross alpha and beta activity is due to the alpha and beta radionuclide, with the highest effective dose coefficient, namely 210Po and 210Pb/228Ra, respectively.

In this study, assessment of levels natural radioactivity in drinking water samples of Misan Province of Iraq was carried out. A total of 33 (Tigris river, station and Tap) water samples collected from eleven places in Misan Province of Iraq. The beta and alpha gross radioactivity of the samples water was measured and an average annual effective dose derived of drinking-water ingestion was estimation utilizing new model a LB-4110 low background gas flow proportional counter. The data indicated that the Beta and Alpha gross activities and annual effective dose in samples did not exceed WHO recommended levels (0.5 Bq/L of Alpha gross, 1.0 Bq/L of Beta gross and 0.1 mSv/y for annual effective dose).

Feed Samples

This study was conducted for natural radioactivity of some fish feed samples in Nigeria, using gross alpha and beta method with protean instrument corporate (PIC) MPC 2000DP detector. The range of the gross alpha concentration for the sample, for the Uranium series was 0.0246 ± 0.0051 Bq/g to 0.0028 ± 0.0055 Bq/g, similarly for gross beta concentration ranges from 0.0651 ± 0.0104 Bq/g to 0.0621 ± 0.0100 Bq/g for the samples. The annual effective doses of the activities for the three sample A, B, and C which were 18.56 μSvy-1, 10.91 μSvy-1 and 17.20 μSvy-1 respectively. The results appeared to be below the standard annual effective dose of 70 μSvy-1 for humans as recommended by (UNSCEAR, 1977 and 1982). This research shows that consumers of fish have no risk of radioactivity ingestion in to the food chain, even though no amount of radiation is assumed to be totally safe because radiation is known to trigger or induce cancer

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.

Radiation Measurements

Studies of gross alpha and gross beta activity in road- and surface-deposited sediments were conducted in three Russian cities in different geographical zones. To perform radiation measurements, new methods were applied which allow dealing with low mass and low volume dust-sized (2–100 μm) samples obtained after the size fractionation procedure. The 2–10 μm fraction size had the highest gross beta activity concentration (GB)—1.32 Bq/g in Nizhny Novgorod and Rostov-On-Don, while the 50–100 μm fraction size was most prominent in Ekaterinburg. This can be attributed to the presence of radionuclides that are transferred through natural and anthropogenic processes. The highest gross alpha activity concentration (GA) in fraction sizes was found in Rostov-on-Don city within the 50–100 μm range—0.22 Bq/g. The fraction sizes 50–100 μm have a higher gross alpha activity concentration than 2–10 μm and 10–50 μm fraction sizes due to natural partitioning of the main minerals constituting the urban surface-deposited sediment (USDS). Observed dependencies reflect the geochemical processes which take place during the formation and transport of urban surface sediments. Developed experimental methods of radiation measurements formed the methodological base of urban geochemical studies.

<div><p><em>Human can be exposed to the radiation emitting from different radioactive sources depending upon their activities and surroundings. Human activities have contributed to the increased concentration of some radionuclides in the environment. A survey of the gross alpha and gross beta activity in soil samples collected along the three southern districts of TamilNadu has been carried out. Determination of the gross alpha and gross beta activity concentration are done by using ZnS (Ag) and low beta counter. The gross alpha activity varies from 162.3 Bq/kg to 3679.6 Bq/kg near the sea and ranges from 107.5 Bq/kg to 1774.1 Bq/kg 150 m away from the sea. The gross alpha activity in the sub-urban area varies from 53.67 Bq/kg to 644.12 Bq/kg. The gross beta activity concentration in the soil ranges from 388.8 Bq/kg to 40111.1 Bq/kg in the coastal region (near the sea) and ranges from 669.06 Bq/kg to13278.4 Bq/kg (150 m away from the sea). While the gross beta activity concentration in the sub-urban area varies from 1103.05 Bq/kg to 4202.12 Bq/kg. The obtained values shows soil from the sampled locations may pose some long time health hazards to the public. Statistical analysis are also performed between the soil samples. <strong></strong></em></p></div>

AbstractMeasurement of the gross alpha and beta activity concentrations in various matrices is suitable as a preliminary screening procedure to determine whether further analysis related to specific radionuclide is necessary. In Serbia, according to current regulations, radioactivity concentrations in drinking water for gross alpha and gross beta should be < 0.5 and < 1.0 Bq L

Abstract There is little available information on the radioactivity concentrations in the thermal and drinking water sources in North Vietnam. In the current study, the gross alpha and gross beta activity concentrations were determined in 8 water sources in the area. The average activities of gross alpha and beta in the 8 sources are 38.7 mBq L− 1 and 88.0 mBq L− 1. These activity concentrations are lower than WHO recommendations for drinking water. In this study, the gross alpha and gross beta show a weak correlation.
