“…The duration of enrichment is typically on the order of several days. Enrichment factors for standard treatments range from 6-100 [140], [141]. The need to achieve specific enrichment factors can be dictated by other experimental limitations, such as the sensitivity of the counting system being used to analyse the enriched sample, or time constraints of the project.…”

“…electrolysis more rapidly in comparison to the heavier tritium. Electrolytic enrichment techniques have been described byTakahashi et al (1968) [136],Taylor (1981) [137],Sauzay and Schell (1972) [138], Cook et al (1998)[139], and Wallova et al (2020) amongst many others[140]. The reduction in overall volume leads to an enrichment of the HTO molecule, referred to as the enrichment factor.…”

“…Based on our preliminary data, if tritium concentrations were assessed in water samples across the country, they could then be used as a basis for comparing tritium concentrations and assessing the future impact on nuclear power plants. However, if the tritium content is below 1.0 Bq/L, the electrolytic enrichment method is required since it provides an extremely low MDA value (Wallova et al, 2020;Lin et al, 2020), but is more laborious than the conventional distillation method (Hou, 2018).…”

Monitoring of tritium concentration in tap water is an essential tool to determine the effective dose received from tap water. Liquid scintillation counting (LSC) is a widely used technique for determining tritium in water. Due to the very low activity of tritium in tap water, its detection requires a high-efficiency LSC with the lowest minimum detectable activity (MDA). Low-level tritium analysis in tap water were performed in two LSC models using conventional distillation techniques. The optimal conditions with the lowest MDAs were applied to determine the tritium concentration in the tap water distributed from two main sources located in the Bangkok metropolitan region: Bang Khen and Maha Sawat water treatment plants (WTPs). Twenty-six tap water samples were collected from petrol stations located around both water treatment plants. The results revealed that the amount of tritium in the tap water around the Bangkhen WTP was between 1.88-2.63 Bq/L with an average of 2.28±0.28 Bq/L, whereas those from the Maha Sawat WTP were between 2.01-2.69 Bq/L with an average of 2.44±0.26 Bq/L, which are far below the World Health Organization’s (WHO) guideline limit (10,000 Bq/L) for drinking water. The annual effective dose (AED) for infants, children and adults obtained from tap water samples around the Bangkhen WTP were 0.010, 0.014, and 0.030 µSv/year, respectively, and those from the Maha Sawat WTP were 0.011, 0.015, and 0.032 µSv/year, respectively, which are far below the WHO’s guideline limit (100 µSv/year).

The aim of this study was to test two potential tritium determination methods (with and without electrolysis enrichment) suitable for low-level measurements. Both methodologies were applied to water samples from the Baltic Sea and ten Polish rivers providing new data on tritium activity concentration. Optimization steps carried out to the standard method lowered minimum detectable activity concentration (MDC) from 3.1 to 1.8 Bq L–1 (at 95% confidence level) enabling to apply it to environmental water samples. However, electrolytic enrichment method of MDC of 0.20 Bq L–1 provided more accurate results for tritium activity concentration in surface waters.
