Abstract

The fallout radionuclide (FRN) analysis needs a reference site (RS) inventory to determine erosion and sedimentation in the study area. The investigated area is in the upstream Citarum watershed, West Java, Indonesia. Twenty-seven corings and 22 scrap samples have been prepared well and measured using HPGe gamma spectroscopy. The data below the minimum detectable activity (MDA) was found for 137Cs in RS6 cor 4 and 7 (<0.16 ± 0.08 Bq kg-1). MDA quantification implies that the inventory below MDA eroded greater than its maximum value (76.02 tons ha-1 a-1). The comparison 137Cs inventory in this study is lower than the three estimation models; however, the inventory of Mt. Papandayan is closer to the model. This study found the depth percentage of 20-30 cm using the proportion of 0-20 cm/0-30 cm ratio and predicted the portion of the existence of 137Cs and 210Pbex in the 20-30 cm in the bulk sample. The highest H0 (142.04 kg m-2), the relaxation length λ, and proportion of 20% of 137Cs in 20-30 cm depth imply that 137Cs inventory activity is possibly deeper than 30 cm. This study recommends that Mt. Papandayan could be the alternative RS for the upstream Citarum watershed.

印度尼西亚西爪哇上游Citarum流域3个侵蚀研究候选参考点的137Cs和210Pb存量变化
放射性落尘核素(FRN)分析需要参考点(RS)清单来确定研究区域的侵蚀和沉积。调查区域位于印度尼西亚西爪哇Citarum流域上游。制备了27个岩心和22个废石样品,并用HPGe能谱仪进行了测量。在RS6 cor 4和rs7(-1)中发现137Cs低于最低可检测活性(MDA)的数据。MDA量化表明,低于MDA的库存侵蚀大于其最大值(76.02 t ha-1 a-1)。本研究比较的137Cs库存低于三种估计模型;然而,帕潘达扬山的库存更接近模型。本研究利用0-20 cm/0-30 cm的比值求出了20-30 cm的深度百分比,并预测了体积样品中20-30 cm中137Cs和210Pbex的存在比例。最大的H0 (142.04 kg m-2)、弛豫长度λ和20%的137Cs在20 ~ 30 cm深度的比例表明137Cs库存活动可能在30 cm以上。本研究建议,帕潘达扬山可以作为上游Citarum流域的替代RS。

期刊介绍: Isotopes in Environmental and Health Studies provides a unique platform for stable isotope studies in geological and life sciences, with emphasis on ecology. The international journal publishes original research papers, review articles, short communications, and book reviews relating to the following topics: -variations in natural isotope abundance (isotope ecology, isotope biochemistry, isotope hydrology, isotope geology) -stable isotope tracer techniques to follow the fate of certain substances in soil, water, plants, animals and in the human body -isotope effects and tracer theory linked with mathematical modelling -isotope measurement methods and equipment with respect to environmental and health research -diagnostic stable isotope application in medicine and in health studies -environmental sources of ionizing radiation and its effects on all living matter
