Water Resource Management radioisotopes are used to trace theorigin of ground water and measure therate of groundwater replenishment. 6. MonitoringSoil Erosion and Sedimentation Artificial radioisotope Cesium-137 is used to estimate rate of soil erosion and sedimentation. has a half life of 30 years , it is still detectable today. It sticks to clay materials is soil and is non- exchangeable , making it an efficient tracer of surface soil movement. 7. Management of Red Tide Nuclear techniques are used to assist in themonitoring and management of toxic HarmfulAlgal Bloom(HAB) commonly known as redtide. 2 Nuclear Techniques used to detect HAB Saxitixin receptor blinding assay. Lead -210 Dating Method used to determine thehistoric profile of sedimentscore in HAB- affected areas. PNRI- Philippine Nuclear Research Institute 8. Identification of Major Sources of Air Pollution Air particulate samples are collected over a long period of time to obtain information necessary to determine air pollution source. Vehicular emission are the primarily source of pollution at ADMU according to the study of PNRI. 9. Mineral Analysis Probes containing radioisotopes and a detector are immersed directly into slurry streams. Signal from proves are processed to measure the density & concentration of the element s being monitored Examples of radioisotopes being used: Carbon-14 used to measure the age of ground water Chlorine-36 used to measure sources of chloride andage of water Lead-210 used to date layers of sand and soil up to 80years 10. Sterile Insect Technique (SIT) Used to control the production of peststhat destroy fruit and vegetables crops 11. Food Irradiation Is a safe physical means of food processing and preservation similar to methods such as refrigeration, freezing, canning , heat treatment Food is exposed to prescribed dose of high- energy ionizing radiation w/in an enclosed system for specific span of time Uses: Reduces post-harvest losses & disinfest agriculturalcommodities necessary for long storage or transport. Extends shelf-life of a product by reducing microbes 12. Daily Cattle Productivity Radioimmunoassay(RIA) A nuclear technology that used to improve the breeding management of dairy cattle. Used to monitor the efficiency of artificial insemination in dairy cattle and to identify the best time for breeding. 13. Carrageenanas Plant Growth Promoter Carrageenan is a natural extract from Eucheuma seaweeds. Irradiated kappa carregeenan (KC)have the potential to stimulate the growth of rice seedlings, vegestables , & tissue-cultured chrysanthemums according to PNRI. Irradiated KC has been discovered to increase the formation of chloropyll. 14. Promotion of Agro-forestry System Nitrogen -15 Tracer Techniques Is the best cropping practice and tree-crop interaction technology that can be identified using nuclear technique. Farmers can reduce fertilizer input without any decrease in their crop yield. 15. Soil Fertility Nitrogen-15 Tracer Technique Can also applied to identifying efficiency rates of inorganic-organic fertilizer combination in rice based cropping system. Can also used to measure the amount of nitrogen absorbed by rice plant at various stages of growth. 16. Conversationof Sugarcane Waste into Useful Products Gamma Radiation & Fermentationprocesses can convert sugarcane wasteinto: Bagasse Irradiated bagasse can feed for ruminants suchas cows. Mud press 17. MutationBreeding Improved characteristics are producedusing: Gamma Radiation Tissue Culture Technique Related Biotechnology Applied to rice & indigenous ornamental andfoliage plants to enhance their desirablequalities. 18. Carbon Dating Carbon-14(C-14) Is a radioactive isotope of the element carbon and is produced in the upper atmosphere by radiation from the sun. Is also a fraction of the carbon plants gets from carbon dioxide. Has a half-life of 5730 years Reasons why some fossils cantt be carbon dated: Too old Rarely contain original carbon Most carbon content comes from contaminated source. 19. UraniumDating Lead Discovered to be the final product of uranium decayseries 20. Radioimmunoassay Carrageenanas Radiation Dose Indicator Radiation-Modified Carrageenan for WoundDressing Radiation-Sterilized Amniotic Membranes asBurn Dressing 21. Radioimmunoassay (RIA) Noble Prize awardeeSussman-Yalow togetherRoger Guillemin and AndrewSchally. RIA detects and measuresminute quantities of substancein the blood with radioactivelabal. Used to study theconcentration of insulin in theblood of a diabetic during 1959. 22. Carrageenan as Radiation Dose Indicator Also known as Go-no-Go Important tool in qualoty control in industrialprocessing such as medical productsterilization. Composed of acid-sensitive dye mixed withcarrageenan. 23. Modified Carrageenan forRadiation Wound Dressing PNRI formulated hydrogel dressing fromcarrageenan which is clinically tested onburn patient. 24. Radiation-Sterilized Amniotic Membranes as Burn Dressing Amniotic Membrane from human placenta are cleaned , tested for viruses, freeze-dried , and packaged in special bags before being sterilized using gamma radiation. Radiation Sterilized membranes have been clinically proven to be effective as dressing for bed sores, wounds, and burns. 25. GammaRadiographyGamma Column Scanning TechniqueGaugingGamma SterelizationJewerly Industry 26. Gamma Radiography Used to detect internal defects in materials such as pipelines without damaging the material Can be used to check the integrity of welds in gas or oil pipelines. Uses special film tape taped over the weld A shielded Radioactive sources is carried down the inside of the pipe to the weld by a machine called Pipe Crawler. This technology also used to determine cracks in buildings and railroads 27. GammaColumn Scanning Technique Used to see inside a process vessel made of steel and locate internal defect without disrupting normal plant operations. Uses a sealed radioactive material and a detector to obtain a clear picture of conditions inside the process vessel from top to bottom 28. Gauging Used to measure the thickness of plastic films and different types of coating. Radiation Detector measures the intensity of the radiation. 29. Gamma Sterelization Is used for sterilizing medicalproducts , wool, food. Cobalt-60 is the main isotopeused since it is an energeticgamma emitter. 30. Jewerly Industry Radioisotope-excited X-ray flourescence (XRF) spectrrometry - used to analyzed the quality of a jewerly.
