Activity concentration of the 222Rn radionuclide was determined in drinking water samples from the Sothern Greater Poland region by liquid scintillation technique. The measured values ranged from 0.42 to 10.52 Bq/dm3 with the geometric mean value of 1.92 Bq/dm3. The calculated average annual effective doses from ingestion with water and inhalation of this radionuclide escaping from water were 1...

Introduction Iron ore is one of the most important natural raw materials that is widely used for manufacturing iron and steel. This type of ore contains various amounts of radionuclides; thus, exposing workers handling their extraction, transportation, and processing to radiation. Materials and Methods In this study, 12 ore samples (each mass weighing about 2 kg) were collected from the iron or...

introduction foodstuffs are known to contain natural and artificial radionuclides. determination of radionuclide concentration is of great significance for the protection of human health. the main objective of the present study was the quantification of radionuclides in tea samples, cultivated in guilan province in north of iran. materials and methods the activity concentrations of 226ra, 232th...

A three–module ecological model for assessment of radiological consequences (EMARC) of accidental fallout was developed to estimate the internal dose. The model was adapted for ecological and economic conditions of Ukraine after the Chernobyl accident. The model takes into account the main natural mechanisms of changes in level of agricultural production pollution such as transformation of bioa...

As part of a regional baseline study, the distribution naturally occurring radioactive materials in marine fish diversity consumed by different age group representatives living Kalpakkam coastal zone was studied. The average activity natural radionuclide 238U, 232Th, and 40K (n = 40) 28.51, 239.58, 118.95 Bq kg-1, respectively. annual dose ingestion, lifetime carcinogenic risk assessment cancer...

The aim of the study was to determine activity concentration natural radionuclides (226Ra, 210Po, 228Ra and 40K) artificial radionuclide 137Cs in muscle marine fish species most consumed city São Paulo evaluate annual effective dose due consumption fish. Samples were collected supermarket chain Extra Carrefour distribution center CEAGESP. Six selected among available city: anchovy, tuna, dogfis...

Measurement of natural radionuclides concentration in Samosir area of Sumatera island of Indonesia aims to obtain basis data of the content of radionuclides that could be tended in the development of the area. This research was conducted using Neutron Activation Analysis (NAA), which consists of a sampling of soil of Samosir Island as the residential area and the soil surrounding of Pangururan ...
