Today, nuclear technology has become one of the most interesting research objects in the world. With 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 received 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. 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 and grass, 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.
