摘要

自然环境中的氡气主要来源于当地基岩地质的释放，容易在地下室、洞穴等封闭空间中富集。本研究调查了南苏拉威西马罗斯喀斯特地区bantimurung - buusaraung国家公园Mimpi洞的氡浓度，并讨论了氡浓度与当地地质之间的可能关系。使用CR-39核径迹探测器的被动探测技术进行测量，将其暴露三个月。洞内测得的222Rn水平范围为64.03 ~ 3396.02 Bq m - 3，平均值为1075.05 Bq m - 3。这些结果与几个国家其他调查报告的不同洞穴环境中的氡浓度相当。马罗斯喀斯特地区的地质背景可以维持测量到的氡值，因为石灰岩的矿物组成可能导致Mimpi洞穴中的氡浓度较高。

Geologic Influence on Radon Concentrations Levels in Cave: A Case Study of Mimpi Cave in the Maros Karst of South Sulawesi, Indonesia

Radon gas in the natural environment mainly comes from the release of local bedrock geology and easily accumulate in closed spaces such as basements and caves. This study was performed to investigate the radon concentrations in Mimpi Cave, Bantimurung-Bulusaraung National Park, in the Maros karst area, South Sulawesi, and discussed a possible relationship between the radon concentrations and the local geology. Measurements were carried out using a passive detection technique with CR-39 nuclear tracks detectors by exposing it for a period of three months. The 222Rn levels measured inside the cave ranges from 64.03 Bq m‑3 to 3396.02 Bq m‑3, with an average value of 1075.05 Bq m‑3.The results are comparable with radon concentration in different caves environments reported from other surveys in several countries. Geological background of the Maros Karst areas could sustain the measured radon values, due to the presence of limestone rock with a mineral composition which can lead to higher radon concentrations in Mimpi Cave.
