        The primary objective of radiological environmental monitoring after a radiological emergency at a nuclear facility is acquisition of background data for the determination of protective actions for the population and the comprehensive assessment of the impact on the population residing in proximity to the nuclear facility. The responsible entities engaged in the conduct of the radiological environmental monitoring encompass government organization and nuclear licensees, operating in strict adherence to the national radiological disaster prevention framework. In accordance with the national radiological disaster prevention framework, radiation environmental monitoring is executed through the deployment of emergency response organization, and recurrent exercise drills aimed at augmenting responsible capabilities. In the context of radiation environmental monitoring, it is necessary to specify measurement parameters, monitoring location, and methodological protocols for each stage, considering potential exposure pathways. In terms of equipment, it is important to utilize mobile assets such as aerial or vehicle surveys for rapid and accurate radiation environment monitoring. Radiation disaster drills are regularly conducted, and the radiation environment monitoring field is also regularly trained to enhance response capabilities. The scale of these drills may vary, ranging from exclusive participation by nuclear licensees to joint exercises conducted by governmental agencies. This iterative process of periodic drills and equipment enhancements has led to a progressive augmentation of environmental monitoring capabilities, ensuring a well-coordinated orchestration of radiation monitoring within the framework of radiation protection. Notwithstanding these achievements, challenges in public communication regarding the decision to take protective actions and the dissemination of information to the public. Considering that the purpose of radiation environmental monitoring extends beyond safeguarding public health; it also serves to alleviate public anxiety. In the future, public communication between these stakeholders should also be included in disaster drill programs to ensure proper consultation between each stakeholder during drills and to build understanding and trust in radiation environmental monitoring. This is expected to improve the quality of radiation environmental monitoring response capabilities.

        There is much evidence suggesting that compounds present in soybean can prevent cancer in many different organ systems. Especially, soybean is one of the most important source of dietary saponins, which have been considered as possible anticarcinogens to inhibit tumor development and major active components contributing to the cholesterol-towering effect. Also they were reported to inhibit of the infectivity of the AIDS virus (HIV) and the Epstein-Barr virus. The biological activity of saponins depend on their specific chemical structures. Various types of triterpenoid saponins are present in soy-bean seeds. Among them, group B soyasaponis were found as the primary soyasaponins present in soybean, and th e 2, 3-dihydro-2, 5-dihydroxy-6- methyl-4H-pyran-4-one(DDMP)-conjugated soyasaponin α~textrmg , β~textrmg , and β a were the genuine group B saponins, which have health benefits. On the other hand, group A saponins are responsible for the undesirable bitter and astringent taste in soybean. The variation of saponin composition in soybean seeds is explained by different combinations of 9 alleles of 4 gene loci that control the utilization of soyasapogenol glycosides as substrates. The mode of inheritance of saponin types is explained by a combination of co-dominant, dominant and recessive acting genes. The funtion of theses genes is variety-specific and organ specific. Therefore distribution of various saponins types was different according to seed tissues. Soyasaponin β~textrmg was detected in both parts whereas α~textrmg and β a was detected only in hypocotyls and cotyledons, respectively. Soyasaponins ~gamma g and ~gamma~textrmg were minor saponin constituents in soybean. In case group A saponins were mostly detected in hypocotyls. Also, the total soyasaponin contents varied among different soy-bean varieties and concentrations in the cultivated soy-beans were 2-fold lower than in the wild soybeans. But the contents of soyasaponin were not so influenced by environmental effects. The composition and concentration of soyasaponins were different among the soy products (soybean flour, soycurd, tempeh, soymilk, etc.) depending on the processing conditions.
