Charged particles create their tracks in most dielectric solids. These tracks can be viewed under optical microscope after proper chemical etching. Tracks of uranium fission fragments in obsidians also can be viewed after etching by HF solution and used for age dating. In this paper, dating formula and experimental procedures for fission track dating are introduced. And spontaneous and induced fission tracks by thermal neutrons are counted under optical microscope (magnification of 400x). Measured fission track ages of obsidian samples, OM No. 147 and HM No. 40 are 8.86 x 10 exp (5)y and 7.67 x 10 exp(5)y, respectively.

世界平和와 韓國의 役割

姜永晧,李瑛雨,金宇泰 경북대학교 법정대학 1976 法大論叢 Vol.14 No.-

World peace is an ideal which mankind has been searching for a long time. The League of Nations and the United Nations, established after World War Ⅰ and Ⅱ respecetively, were the results of the desire of peace-loving people attempting to solve international disputes and conflicts by peaceful means. Following the end of World War Ⅱ through 1950's the world has experienced a period of Cold War, replaced by an era of peaceful co-existence during 1960's. In 1970's the thaw in the struggle among big powers developed which further lessened the likelihood of war among the super powers. Taking advantage of improving international atmosphere, however, north Korean Communists have disguised themselves as the champion of peace and offered many so-called "peaceful unification formulas", thus misleading the world opinion. It is the objective of this paper to correct the misinformation concerning the problem of peace in Korea and to reveal true motive of the north Korean Communists by clarifying ROK's position on the issue of peaceful unification of the Korean Peninsula. Chapter Ⅰ is an introduction to this paper stating the problems and issues to be discussed in the paper. Chapter Ⅱ deals with putting Korean people's view of peace on the basis of the world peace by making clear the true idea of peace through historical development of peace theory in western history and searching the types of the world peace. Chapter Ⅲ is a study of peaceful nature of Korean people from the perspectives of Korean history. In order to make an effective analysis on above issue the Chapter is divided into three parts: first, a brief examination of the origin of Korean race; second, a study of Korean history based on mythology such as "Hong-Ik In-Gan" philosophy found in Dan-Gun myth and "So-Do" philosophy prevelant during the period of Three Hans; third, a historical recollection of numerous invasions of the Korean Peninsula by foreigners and yet the fact that at no time had Korea invaded its neighboring countries. Chapter Ⅳ deals with a period since the second World War, and particulary since the establishment of the Republic of Korea in 1948, in which the Korean Government, inheriting the spirit of peaceful nature of its people, has been pursuing peace. The Chapter is divided into two parts. The first deals with the period up to 1970 during which the R.O.K. was established (in 1948), the Korean War was erupted (in 1950), and the normalization of relations between Kore and Japan was achieved (in 1965). Internally, political stability and economic growth were realized in order to establish a firm base for an eventual peaceful unification of the Peninsula. Externally, this period saw the Republic of Korea expanding its diplomatic activities by establishing multilateral relationship with foreign countries. Since the beginning of the 1970's. President Park Chung Hee has universally published a series of epock-making plans to settle peace on the Korean Peninsula. President Park's August 15 Declaration (1970), a south-north joint communigue´ (1972), the declaration of a new foreign policy for peace and peaceful unification (1973), the proposal of non=aggression pact between the south and north (1974), and the proposal of three basic principles for peaceful unification (1974)-these are the expressions of the R.O.K.'s efforts to settle peace on the Peninsula and to contribute actively to the world peace. By studying the contribution of Korea to the world peace, it is hoped that the efforts by the Korean Government by clearly understood and this article would contribute in a small way toward the eventual unification of the Korean Penininsula.

Dielectric materials can record charged particle tracks. After the discovery of track etching method, these dielectric materials, known as Solid State Nuclear Track Detectors (SSNTDs), are widely used and investigated for detection of charged particles. In this work, we studied electrochemical etching (ECE) of CR-39 plastic and antomatic spark counting method of alpha tracks in cellulose nitrate (CN), and determined neutron flux of TRIGA MARK Ⅲ Reactor of Korea advanced Energy Research Institute (KAERI). The formation of track pit and tree in ECE can be explained by ECE process model proposed by Tommasino et al., and this treeing phenomena in ECE process may be considered combined effect of applied AC field and reaction of chemical etchant. With the ECE vessel designed by Somogyi and high voltage function generator, alpha tracks in 1.64㎜ thick plate of CR-39 plastics were electrochemically etched. Etched tracks enlarged by treeing phenomena could be observed by naked eyes. By increasing the ECE time, track density and diameter increased. And linear dependence of track diameter on applied voltage was seen. The obtained optimum ECE conditions for alpha tracks in CR-39 are following; 60℃ 30% KOH etchant, 7KV 45.5 KHz applied field, 3 hrs etching time. Electric discharge may occur through track perforations. Using the thin foil of alminized mylor, it was possible to obtain the one time discharge for one track perforation. After the irradiation of alpha particles, CN detectors were chemically etched in 60℃, 10% NaOH, for 120 min. Then, alpha tracks in 12 ㎛ CN were counted automatically by designed spark counter. Our spark counter have counting area of 2.40 ㎠. Threshold and operating voltage for 12 ㎛ CN were 190 V and 300 V, respectively. The determination of neutron flux of TRIGA MARK Ⅲ Reactor was performed by NBS standard Glass, SRM 961 and SRM 964. The measured neutron flux of TRIGA MARK Ⅲ was 3.6×10 exp(11) n/㎠·sec at 1.5 ㎿ reactor power. And uranium solution-mica pari made in our laboratory was also used for neutron flux determination. The measures neutron flux was 2.97×10 exp(11) n/㎠·sec and this was somewhat lower than the measured value by standard glass. This difference may be caused by non-uniformity of uranium atoms deposited on the acryl substrate.

姜榮浩,李相潤 慶北大學校 1979 論文集 Vol.27 No.-

Since July 1956, the survey of environmental radioactivity has continuously been carried out as a fall-out program. This report concerns radioactivity in Air-borne dust, Fall-out, and Rain-out measured in Daegu area (N. lat. 35°53′, E. long. 128°37′) during the period of 2 years from January 1, 1977 to December 31, 1978. This report includes special survey results from the 22th, 23th, and 24th nuclear explosion tests carried out in the Lop Nor (N. lat. 40°, E. long. 90°), China. The results of these measurements are as follows; 1. The annual average values or radioactivity of the Air-borne dust collected by the air sample in this period were (2.95±0.02) pμCi/cc (6hr.), and (0.08±0.01) pμCi/cc(120hr.). The maximum radioactivities in this period of investigation were (19.61±0.58) pμCi/cc (6hr.: Feb. 11.'77), and (0.52±0.20) pμCi/cc (120hr.: Jun. 13, '77). 2. The annual average values of radiocativity of the Fall-out collected by gummed papers in this period were (0.23±0.02) mCi/㎢-10d. (6hr.), and (0.13±0.02) mCi/㎢-10d. (120hr.). While the maximum values of radioactivities during the period were(2.31±0.21) mCi/㎢-10d. (6hr.: Oct.1∼11,'77), and (1.63±0.20) mCi/㎢-10d. (120hr.: Oct.1∼11, '77). 3. The annual average value of radioactivities in the Rain-out collected at fixed time daily were (0.84±0.19)×10 exp(-8)μCi/cc(120hr.), and the maximum values of the radioactivities during the period were (8.93±1.02)×10 exp(-8) μCi/cc(6hr.:Oct., 6∼7 '77), and (7.55±1.00)×10 exp(8)μCi/cc(120hr. : Oct.6∼7, '77). 4. The results of the environmental radioactivities caused by these three time-nuclear explosion tests (22th, 23th, and 24th) were much smaller than those of the former tests(1st through 21th). 5. According to the above data obtained, we have found that the maximum permissible concentrations (M.P.C.∼10^-7μCi/cc for water, 4×10 exp(-13)μCi/cc for air) are not reached both in water and in air.

姜榮浩,李相潤 慶北大學校 1968 論文集 Vol.12 No.-

An investigation of the envrionmental radioactivity of rain water, fallout and air-borne dusts in Tagu area (E.long.128˚37',N.lat.35˚53') during a period of June, 1966 to May, 1968 has been made. During this period, there were four-times nuclear bomb tests by Red China. The results of these measurements are as follows; 1. The annual mean values of radioactivity in the rain water collected at fixed time daily were (2.15±3.08) μμ Ci/cc(1966) and 7.77±0.05) μμ Ci/cc(1967). The maximum value of the radioactivity during the period was (270.27±0.72)μμ Ci//cc on Dec. 30,1966. It seemed to be caused by the fifth nuclear bomb test by Red China on Dec. 28,1966. 2. The annual mean values of radioactivity of the fallout collected by gummed papers in 1966 and in 1967 were (46.92±0.08 muCi/ft^2-10d and (1.00±0.02) mu/Ci/ft^2-10d, respectively. The maximum radioactivity (161.1±0.15)muCi/ft^2-day(Dec.30,1966) in this investigation period was seemed to be caused by the fifth nuclear bomb test (Dec. 28, 1966) by Red China. 3. The annual mean values of radioactivity of the air-borne dusts collected by the air sampler in 1966 and in 1967 were (23.19±0.38) pu Ci/cc and (14.05±0.32)puCi/cc, respectively, The maximum radioactivity in this investigation period was(345.9±1.5) puCi/cc(Dec. 30,1966). 4. The environmental radioactivities caused by the fifth nuclear bomb test is enormously higher than that of the first test. (Dec. 16, 1964). 5. Ce^141, Ce^144, Ba^140, Ru^103, Rh^106, Zr^95, and Nb^95 nuclides were detected with gamma-ray spectrometry. 6. Autoradiographic exposure was made for falling dust samples, and the concentration of fallout particles was estimated by inspecting the autoradiography.

大邱地區의 放射能에 對하여

We are under the influence of natural radioactivity and artificial radioactivity caused by the experimets with atomic and hydrogen bombs. Among those radioactive isotopes are Sr 90 and Ce 144 which have been proved to be critically harmful to human bodies. Since such radioactive substances are being accumulated in the atmosphere and soil, the measurement of their intensity at present will be of considerable importance in order to make comparison with future data. This experiment was done with subsurface water, rain water, edible vegetables and some other plants available, and the results were as follows; (1) There have no great influence on mean value of background. (2) Mean value for subsurface water were very small compared to that for rain water. (3) By Table 12. it clear that isotopes in rain water have long half lives. According to the Nuclear Decay Chart (General Electric Co. USA 1956). Those isotopes were seemed to be Sb^126(28d), Cr^51(27d), Cm^24(27d), Pa^233(27.4d), Nb^95(35d), Cm^241(35d) and W^185(74d), but chemical analysis for those isotopes were not done yet that it remains to be determined whether rain water actually contains the above mentioned isotopes or not. (4) The wild edible vegetables, in general, are more radioactive than cultivated vegetables. (5) It may be that the geometrical differences of plants have a great influence on the degree of contamination; i.e. plants with big leaves with hairs are more severely contaminated than plants with small leaves and fragile stems.
