| Summary: | Today, nuclear technology has become one of the most interesting research objects in the world. With the many nuclear reactors operating in the world, both power reactors and research reactors, and the application of nuclear technology in all fields can have a detrimental effect in the form of releasing radioactive material into the environment. Other than that, there are also natural sources of radiation that have emerged naturally due to natural symptoms that occur on earth and radiation that is in the human body (internal radiation). Natural radiation is the biggest contributor to the radiation source that humans receive about 85% of the total radiation that humans receive in one year. So it is important to monitor radiation in an area, especially radiation from natural sources. Natural radiation monitoring is carried out by mapping natural radiation of certain areas, so that spots of the area are found which have anomalies in environmental radioactivity. In addition, it is necessary to study radionuclide transfer factors for environmental elements such as soil, plants, etc. Besides plants, transfer factors for animal products are needed, such as meat, eggs and milk which routinely enters the human body. This study used an experimental method by measuring radionuclides in several samples. Sampling is done in an area in Lembang. The samples taken were soil, grass and cow's milk, then measured using an ORTEC gamma spectrometer with HPGe detector. Based on the measurement of samples, it can be concluded that in the area there is no anomaly of radioactivity in the environment and still at a safe level of radiation. Then, the radionuclide transfer factor is found which varies on the soil to grass and grass to cow's milk samples. |
