Abstract

Chemical fertilizer is a mixture of chemical compounds which provide for the needs of chemical elements and nutrients in plants (Chauhan et al., 2013). One example rather than chemical fertilizer that is widely used as a fertilizer phosphate. Phosphate rock is the starting material for the production of all products are the main source of phosphate and phosphate fertilizers (Roselli et al., 2010).Natural uranium in phosphate rock has the properties can replace the position of calcium, resulting in a certain time will accumulate uranium in fertilizers. the existence of uranium in phosphates depending on levels of uranium in phosphate rock (Indri et al., 2006). In the manufacture of phosphate fertilizers, many radionuclides come into the fertilizer, so fertilizer spreading into the environment and become NORM radioactive sources (Rehman et al., 2006). This study was conducted to determine the radioactive material (NORM) in the chemical fertilizer in Indonesia using gamma ray spectrometry. Based on the research that has been done, it can be concluded that the six types of samples of fertilizers namely Urea, ZA, KCL, NPK, TSP and Phosphate has a content of natural radioactive materials (NORM).
