An underwater radiation monitoring system has been developed using a NaI (Tl) detector for the potential radioactive contamination of drinking water by 137Cs and 131I radioisotopes. In this study, experiments and simulations were carried out using the detector to evaluate the minimum detectable activity (MDA) and conversion factor (converting counts into Bq·L-1) of radioisotopes 137Cs and 131I. For the experiments, a waterproof system with the detector was located at the center of a water tank into which 68Ga was homogeneously diffused instead of 137Cs and 131I due to a radwaste problem, and detection counts were recorded for every 5 min. Monte Carlo simulations were carried out for 68Ga with the same geometry as the experiment to compare with the experimental energy spectrum to obtain simulation calibration value, and simulations were then performed for 137Cs and 131I to calculate the conversion factor. From the simulations, the conversion factors were 1.74×10-2 and 1.30×10-2 (Bq·L-1)/count for 137Cs and 131I, respectively. From underwater radiation background data and the conversion factors, the MDA of 137Cs and 131I for the system were found to be 0.77 and 0.89 Bq·L-1, respectively.

The concerns about the potential contamination of drinking water with accidental nuclear matter have been escalated as more nuclear power plants are being constructed in many countries. Radiation monitoring systems in water environment are basically the same as the conventional ones in principle, but its structure needs to be adapted and modified so as to be suitable to the aquatic operation conditions. As a result, its specifications should be investigated in terms of the minimum detectable activity (MDA) as well as the effective detection distance (EDD) because they determine the radiation level that the monitoring system initiates the emergency action to prevent the water source from being contaminated early enough to avoid serious social commotion. In this study, the EDD and the MDA of the monitoring system fabricated by the Korea Atomic Energy Research Institute (KAERI) were measured with 68Ga source. The 68Ga source was mixed with water homogeneously in the experimental device, and detectable area was expanded gradually with detecting gamma emitted from 68Ga source for EDD. Then, the gamma was also detected as a function of time for MDA, because the activity of 68Ga decreases with its half-life. It turned out that the values were 29 cm and 5 Bq·l-1 in the experiments, respectively. Relatively short range of the EDD seems to be natural in water, but it suggests that multiple monitoring system need to be strategically installed in a body of water. the MDA value is far lower than the limitation for drinking water, which is 200 Bq·l-1 for 137Cs.

This study aims at ascertaining what kind of historical vicissitude Korean Swordsmanship, Kumdo has undergone in Korea and how it has grown into a sport match as it is now. In order to achieve these goals, the utility of a sword and the social changes which have made influence on it are focused as a basic viewpoint and perspective. Four problems are thought to be solved; the first is what's the cultural and political meaning of development of a sword, the second is what's the historical vicissitude which the traditional Korean Swordsmanship has undergone, the third is when and how Japanese - created swordsmanship as a sport match was introduced into Korea and how it changed the traditional Korean Swordsmanship, and the fourth is what' s the value and characteristic of Korean Swordsmanship. First, it is necessary to look into the origin and history of the sword. The sword was developed as a living tool at first, but it was changed into a weapon, In the Stone Age, the sword was mainly used as a hunting tool In the Bronze Age and Iron Age, the sword took amain part of weaponry. The bronze dagger was the typical sword type of the Bronze Age. The bronze dagger was originally imported into the Korean Peninsula from the northern tribes in Central Asia and Siberia, but later there appeared a unique type named 'sehyung donggem' In the Bronze Age, a bone dagger was also used as a weapon In the Iron Age, there appeared many kinds of iron swords, which are divided into two categories: the long one and the short. Next, the historical vicissitude of the traditional Korean Swordsmanship has to be examined. The earliest form of Swordsmanship was an aspect of war and conquest in the Bronze Age and Iron Age. In the period of the three Kingdoms(Koguryo, Pagjae, Shille), an advanced form of Swordsmanship started to be developed by soldiers, especially in Koguryo, And 'Bongukgumbup (Swordsmanship of the State)' developed in Shilla is the beginning of the tralitional Korean Swordsmanship. In the early middle age(Korea: ancient Korea), the special forces of Korea named 'Sambyolcho' played an important role in the development of a more advancde form of traditional Korean Swordsmanship. In the late middle age(Chosun), many kinds of books on Swordsmanship were published and the Swordsmanship was adopted as one of the subjects of martial arts in the State Examination. Third, it is important to find out how our modern Swordmanship was intrduced in Korea. Our modern Swordmanship was intoduced as a kind of military arts dy Japanese in the period of their rule over Korea. Japanese prohibited the traditional Korean Swordsmanship and forced their sport-like Swordmanship instead Japanese-created Swordsmanship match(they call it kendo) was originally designed to cultivate mind and body. In the match they use a bamboo sword instead of a genuine one. Since our liberation from Japanese rule, Korean Swordsmanship, which has basically the form of Japanese-created Swordsmanship, has been populstized and has become a daily sport. But it has lost much of its traditional essence as martial arts, for example 'Sangmu' spirit. Fourth and in conclusion, it can be said that Korean Swordsmanship has succeeded in popularization but it needs to restore the secrets and essence of the traditional Korean Swordsmanship and develop its new varaion, which must be not only genetalized and systematic but also theoretically back-upped and functionally enhanccd. To make better Korean Swardsmanship, it is essential to develop new skills and instruments in accordance with our bodily and emotional.

A high-efficiency underwater radiation monitoring system, HydroGamma, has beendeveloped for detecting 137Cs and 131I in the event of waterborne radiation contamination. The systemconsists of a 3-inch NaI (Tl) detector, solar panels for power supply, data acquisition and transmissionmodules, and batteries. HydroGamma also includes a 40K calibration source for remote performanceevaluation and energy calibration. In this study, some simulations and experiments were carried outto evaluate the minimum detectable activities (MDA) of HydroGamma. We installed the HydroGammaat Tapjeongho Lake in Nonsan-si and acquired background data since MDA is calculated based on theexperimental background data. The results show that the minimum detectable activities for 137Cs and 131Iwere 1.78 Bq L-1 and 1.81 Bq L-1, respectively even though the gamma rays emitted from 40K (1,460 keV)affect the minimum detectable activities for them.
