I . Project Title
Radioecological Studies on Terrestrial Food Chain Analysis for Accidental Release
II. Objectives and Importance
A lot of Korean people are concerned about the environmental safety issue of nuclear facilities including 16 nuclear power plants operating in Korea. Especially, because of the site characteristics that agricultural land is widely distributed in the vicinity of Korean NPPs, it is urgently required to have a capability of doing the environmental impact assessment and counter-measure implementation timely and realistically. When the terrestrial ecosystem is contaminated with radionuclides by an accidental release from nuclear facilities, contaminated crop plants would contribute to human internal exposure through food chain. Therefore, understanding the migrational behavior of radionuclides in the ecosystem and their pathways to human is necessary in predicting the environmental impact and implementing a reasonable counter- measure plan for human safety. Since plant contamination parameters of radionuclides are dependent on site-specific factors such as the meteorological condition, soil properties and agricultural practice, the generation of domestic data is quite important.
IX This study was carried out to experimentally analyze the direct contamination pathways of some major radionuclides in Korean staple food crops and produce domestic data on various model parameters concerning the plant direct contamination. Experimental studies were also performed for investigating root uptake by rice in soils collected around NPP sites to produce short-term and long-term site-specific transfer factors.
HI. Scope and Contents
For investigating the contamination pathways of major radionuclides in staple food crops, greenhouse experiments in which rice, Chinese cabbage and radish were exposed to mixed r radionuclides of Mn-54, Co-60, Sr-85, Ru-103 and Cs-134 and H-3 at different growth stages, were conducted to generate data on parameters concerning the direct contamination of those crops. Experiments of the exposure to iodine gas were also performed for rice and radish at their various growth stages to obtain contamination parameters of elemental iodine. Based on data obtained from the experiments mentioned above, a database program was constructed to make it possible to search parameter values for different radionuclides, crops and deposition times in an easy way and have an graphic output of the variation in the contamination parameter with deposition times. Paddy-field soils were collected from 5 or 6 places around Kori and Youngkwang NPPs and physicochemical properties and background radioactivity levels of the soils were investigated. Soil-to-rice transfer factors of Sr-90 and Cs-137 in the collected soils were determined for different RI application times. For Kori soils, transfer factors were also measured in the second year to investigate the yearly variation. In addition, the conceptual design of an automatized experimental greenhouse was performed to be used as a basic material for a detailed design for the construction in the future.
IV. Results
1. Analysis of the contamination pathway of mixed gamma radiomiclides in staple food crops
For rice, Chinese cabbage and radish, the plant interception factor showed little difference among applied radionuclides of Mn-54, Co-57, Sr-85, Ru-103 and Cs-134 and tended to increase as the application time approached the harvest. It increased very rapidly during the early part of growth and very slowly during the late part. The maximum value measured was 0.94 for rice, 0.87 for Chinese cabbage and 0.86 for radish. The remaining percentage at harvest varied with plants and radionuclides. As the application time approached the harvest, the value usually increased. For rice, the remaining percentage was highest in Ru-103 at the earliest application and in Cs-134 at the latest application while for Chinese cabbage and radish, it was highest in Cs-134 at the earliest application and in Ru-103 at the latest application.
XI Translocation factors decreased in the order of Cs-134 > Co-57 > Mn-54 > Sr-85 > Ru-103 for hulled rice seeds, and Co-57 > Cs-134 > Sr-85 > Mn-54 > Ru-103 for radish root. Difference in the translocation factor among radionuclides was by a factor of up to 500 in rice seeds and by a factor of up to 100 in radish root. Variation in the translocation factor with the application time was greater in hulled seeds than in radish root. Of the 5 radionuclides, Cs-134 showed the smallest variation. It was indicated that rain played an important role in determining the remaining percentage in Chinese cabbage and radish. The rain frequency turned out, however, not to significantly affect the remaining percentage in rice when the frequency difference was by a factor of less than 2. Tying the upper end of Chinese cabbage shortly before RI application reduced effectively radionuclide concentrations in the edible portion of the mature plant.
2. Analysis of the H-3 contamination pathway in staple food crops
HTO absorption coefficients in leaf, which are realtive TFWT (tissue free-water H-3) concentrations (percent of the average H-3 concentration in air moisture) in leaf at the end of 1 h exposure of crop plants to HTO vapor in an exposure box, were about 100% in rice but less than 50% in Chinese cabbage and radish. The absorption coefficient decreased in the order of leaf > stem > ear for rice, outer leaves > inner leaves for Chinese cabbage, and leaf > upper root > lower root for radish. The TFWT concentrations at harvest were lower than those at the end of exposure by factors of several hundreds to
xn several hundred-thousands. In the nighttime experiment for rice, absorption coefficients were in the range of 6—37% depending on plant parts and exposure times and dilution factors were also somewhat different from those in the daytime experiment. In the exposure experiments carried out a few days before and after rice heading, the leaf OBT (organically-bound H-3) concentration (Bq per m# of combustion water) at the end of exposure was about 1% of the initial leaf TFWT concentration but the leaf OBT concentration at harvest was only about 0.04 — 0.05% of the initial TFWT concentration. In ear at the end of rice exposure performed during the early seed development, OBT concentrations were 0.6 ~ 0.8% of TFWT concentrations, which were much higher than observed in exposure experiments made during the late seed development. The OBT production factor (percent ratio of the OBT concentration in the edible part at harvest to the initial leaf TFWT concentration) in hulled rice seeds was in the range of 0.01—0.4% depending on exposure times and highest when the exposure was made at the stage of an active seed development. The OBT production factor varied 0.1 3 — 0.35% in outer leaves of Chinese cabbage, 0.02 — 0.66% in inner leaves of Chinese cabbage and 0.1—0.3% in radish on the whole.
3. Analysis of the I gas contamination pathway in staple food crops
Absorption coefficients (deposition coefficients, i/g) of I gas (elemental iodine) for rice at its different growth stages were in the range of 5.1xl0"2-2.1xl0"1 in straw and 2.4xl0"1~8.5xl0"1 in ear. In both parts, the absorption coefficient was highest at the exposure made
Xlll on Aug. 18, a few days after heading. The absorption coefficient in ear was a little higher when the exposure was performed during the early seed development than when it was performed during the late seed development. In straw, however, no noticeable tendency was found about the difference in the absorption coefficient among exposure times. Remaining percentages of I gas at harvest were in the range of 7. 6—22.0% at the pre-heading exposures and in the range of 3.1—7.1% at the post-heading exposures. Even at the pre-heading exposures, early exposures resulted in the much higher percentage than an near-heading exposure. Translocation factors of I gas in hulled rice
—A — Q seeds were in the range of 7.6x10 —9.7x10 ' depending on exposure times. The lowest was observed at the latest exposure and the highest was observed at the exposure made shortly after heading. More than 99% of the remaining activity at harvest was contained in straw. At the early growth stage of radish, the absorption coefficient of I gas in leaves was 1.6 I /g while at the middle and late growth stages, the absorption coefficients in leaves were about 1.0 0,/g and those in the upper root were as low as 0.03 — 0.04 I /g. The retention coefficient (ratio of the amount contained in a plant part at harvest to the amount absorbed by the plant) of I gas in the upper root of the radish plant exposed to I gas 28 days before harvest, was 3.8x10 and that for the whole root was estimated to be not higher than 6.5x10" .
4. Establishment of D/B program for contamination parameters
A D/B program was constructed with the data on various contamination parameters obtained through our experiments.
XIV Soil-to-plant transfer factors, interception factors, remaining percentages and translocation factors of radionuclides (Mn, Co, Sr, Cs, Ru, etc.) were stored in the program and parameter values for different radionuclides, crop plants and deposition times can be searched for. The Visual Basic language was used for constructing the D/B program to promote a windows-based environment and the ACCESS program, which is well compatible with the Visual Basic, was used for data input. The D/B program was named "RTRACK (Radionuclide TRAnsfer data for Crop plants of Korea)."
5. Radioecological studies for paddy-field soils around NPP sites
The pHs of paddy-field soils collected from both Kori and Youngkwang sites were 5 — 6 and their organic matter contents were 2-3%. These properties are characteristic of the soil generated from weathering of granite, which is generally sterile and acidic. The soil concentrations of Cs-137 and Sr-90 are measured to be in the range of 4.5—13.4 Bq/kg-dry and 0.7-2.5 Bq/kg-dry, respectively. These activities belong to the general background levels in Korea. In Kori soils, soil-to-plant transfer factors (m /kg-dry) of Cs-137 and Sr-90 for hulled rice seeds were in the range of 3.8xlO~5 — 2.0xl0~4 and 9.5x10 5~6.5xl0~4, respectively, at the RI application made before transplanting. At the application made shortly before heading, the Cs-137 transfer factors increased by factors of 20 — 30 compared with the pre-transplanting application while the Sr-90 transfer factors increased only by factors of 2—3. As the result, Sr-90 had on an average 3—4 times higher transfer factors than Cs-137 at the
XV pre-transplanting application but to the contrary Cs-137 had 2 — 3 times higher transfer factors at the later application. At the application made shortly after transplanting, Cs-137 and Sr-90 transfer factors were in the range of 1.3xl0~4~4.5xl0"4 and 2.5xl0~4~7.1xl0~4, respectively. Trends of the variations in transfer factors with application times and the difference between radionuclides in Youngkwang soils were similar to those in Kori soils. The Cs-137 transfer factors for hulled rice seeds in Youngkwang soils were not significantly different from those in Kori soils but the Sr-90 transfer factors were on the whole slightly lower in Youngkwang soils than in Kori soils. Transfer factors of Cs-137 were about 2—3 times higher in rice straw than in hulled seeds but those of Sr-90 were about as great as 20—50 times higher in rice straw. Cs-137 transfer factors for straw were higher at the application made shortly before heading than at the pre-transplanting application by factors of up to 20 while Sr-90 transer factors showed no great difference. In straw, transfer factors of Sr-90 were 30—70 times higher than those of Cs-137.
6. Root uptake of Cs-137 and Sr-90 in the 2nd year following their deposition
In Kori soils, the transfer factors of Cs-137 for hulled rice seeds in the second year after RI application were in the range of 2.5x10"5 — 8.3xlO~5 resulting from the decrease by 35—60% of the first year values. In contrast, Sr~90 transfer factors showed little change. Also in straw, transfer factors of Cs-137 decreased to 45—61% of the 1st year to be in the range of 5.1x10 5~2.3x10 4 while those of Sr-90 changed
XVI little to be in the range of 4.6xl0~3~2.4xl0~2. Transfer factors for hulled seeds and straw in the second year were different between Cs-137 and Sr-90 by factors of 4~8 and 50-150, respectively, depending on soils. These difference between the 2 radionuclides were bigger than those in the 1st year.
7. Design of automatized experimental greenhouse
The conceptual design was performed for an experimental greenhouse with automatic weather control system to simulate weather conditions on real agricultural sites. Basic structure, specifications and requirements were given in the design. Also, the design concept of installing and managing large scale lysimeters has been established for the realistic simulation of the farm land. Requirements for climate factors were suggested so as to simulate weathers of the whole year in Korea.
V. Plan for the Use of Results
The experimental results regarding the direct contamination pathways of radionuclides for staple food crops would be used for the establishment of mathematical models for predicting the internal radiation dose of Korean people due to food consumption following an accidental release. The data on radionuclide behaviors in crop plants and the database program constructed would be helpful for universities and other institutes to study related topics.
XVll Soil-to-rice transfer factors obtained from experimental measurements with soils collected around NPP sites can be used for the prediction of radionuclide concentrations in rice when an accident occurs at a specific NPP site. The use of such site-specific data may contribute to the realistic impact assessment and promote residents' confidence in the assessment. These data would also provide useful information for a basic study on the behavior of the element in the soil-plant system and for the establishment of countermeasures for contaminated crop fields. The technology obtained through this study would be applied to assess the behavior of heavy metals and other toxic chemicals in ecosystem. Such applications would contribute to the good relationship between the nuclear industry and other fields worrying about environmental safety. The conceptual design of an automatized experimental greenhouse is going to be used as a basic material for a detailed design for the construction in the future. The greenhouse will make it possible to realistically simulate agricultural sites so the research using it will increase the reliability of data and reduce the uncertainties of our knowledge on the radionuclide behaviors in the terrestial ecosystem.

Experiments of the exposure to iodine gas were also performed for rice j and radish at their various growth stages to obtain contamination parameters of elemental iodine. Based on data obtained from the experiments mentioned above, a database program was constructed to make it possible to search parameter values for different radionuclides, crops and deposition times in an easy way and have an graphic output of the variation in the contamination parameter with deposition times. Paddy-field soils were collected from 5 or 6 places around Kori and Youngkwang NPPs and physicochemical properties and background radioactivity levels of the soils were investigated. Soil-to-rice transfer factors of Sr-90 and Cs-137 in the collected soils were determined for different RI application times. For Kori soils, transfer factors were also measured in the second year to investigate the yearly variation. In addition, the conceptual design of an automatized experimental greenhouse was performed to be used as a basic material for a detailed design for the construction in the future.
