“…The results are shown in Table 6 . This TFWT range is similar to that reported by Kim et al ( 16 , 17 ) and Baburajan et al ( 18 ), but slightly lower than that measured by Baeza et al ( 19 ) and Baglan et al ( 20 ).…”

“…Seaweeds were collected by removing inedible parts (roots and rotten parts) with a knife, and then washing with purified water to remove the residual sediments. Chicken meat were collected after removing the feather and viscera ( 16 ). The sampling quantities were chosen to ensure that the edible part after pretreatment was more than 1 kg; the detailed sampling information is shown in Table 1 and Figure 1 .…”

IntroductionTritium in the environment constitutes a radiological concern because it can become part of the hydrogen pool in environmental and biological reservoirs and thereby expose people to radiation.MethodsTissue-free water tritium (TFWT) analysis in food is an important subject of environmental radiation monitoring which plays an important role in the estimation of health risks from environmental tritium exposure. At present, tritium content in food is generally determined by liquid scintillation counter (LSC). To improve the analytical efficiency in tritium determination, we developed a novel method to treat TFWT in food using microporous membranes.ResultsThe microporous membrane treatment method developed in this study has the following characteristics: It has a wide range of application and can process TFWT samples with conductivity below 5 μS/cm. Sample loss for the microporous membrane treatment is approximately 5%. The average treatment time is only 5 min, significantly shortened compared with the currently used atmospheric distillation treatment method (1.5 h). The results of the comparison and spike experiment show that the samples prepared by microporous membrane treatment provides equally satisfactory tritium measurement results as classic distillation method.DiscussionThe developed microporous membrane method is simple to operate, efficient, and environmentally friendly, and effectively improves the analysis efficiency of TFWT in food.
