“…In the literature, there are various studies about procedures using liquid scintillation counting for the monitoring of gross alpha/beta activities in environmental water. [5][6][7] Also, several studies have suggested using the liquid scintillation spectrometric (LSS) method instead of GFPC due to its advantages of higher detection efficiency and fa-ster analyzing time. [8][9][10][11] Liquid scintillation spectrometric is an analytical technique which measures activity of radionuclides from the rate of light photons emitted by a liquid sample.…”

The determination of gross alpha/beta activity concentrations of drinking water is the first step of the environmental monitoring studies and can provide a rapid evaluation of the radioactive content of a sample. In this study, a procedure using liquid scintillation spectrometry (LSS) for the simultaneously monitoring of gross alpha/beta activity concentration in drinking water was determined, verificated with proficiency test sample and applied to the real drinking water samples in Turkey. The results indicate that the method provides good accuracy and precision. LSS can be employed as a screening technique in high activity concentrations.

Eng Sanit Ambient | v.21 n.3 | jul/set 2016 | 569-578 RESUMOUma revisão da determinação de alfa e beta total em água, usando espectrometria de cintilação em meio líquido, é apresentada. Foram identificados os principais fatores que influenciam a exatidão e a repetibilidade dos resultados analíticos: pré-concentração térmica, tipo de ácido, janela de contagem e padrão de calibração. Um procedimento analítico foi estabelecido e aplicado a amostras de água de abastecimento público do estado de Goiás para avaliação das radioatividades alfa e beta total. O resumo estatístico dos dados foi realizado por meio dos métodos de análise de dados censurados. Os resultados estão consistentes com os valores de referência do Ministério da Saúde.Palavras-chave: espectrometria de cintilação em meio líquido; alfa total; beta total; água.

Measurement 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 −1 , respectively. The generally accepted methods for gross alpha and beta activity analysis of drinking water in different countries are: EPA 900.0 and ISO methods (ISO 9696, water quality -measurement of gross alpha activity in non-saline water -thick source method, and ISO 9697, water quality -measurement of gross beta activity in non-saline water). This paper describes comparison of preparations and measurement gross alpha and beta activity in bottled mineral waters as well as in tap waters in Serbia using two methods: EPA 900.0 with and without ash, and ISO methods. Concentration of total dissolved solids (TDS) in investigated water samples was determined. Based on obtained TDS, certain volume was evaporated. The instrumentation used to count the gross alpha and gross beta activities for both methods is α/β low level proportional counter Thermo Eberline FHT 770 T.
