Impacts of TENORM from fertilizers on soil and vegetables and the effective dose rate due to ingestion of vegetables at the agricultural zone in Vietnam


In this work, the impacts of TENORM (Technologically Enhanced Naturally Occurring Radioactive Materials) from fertilizers on soil and vegetables were estimated. We investigated both the activity concentration of the natural radionuclides and the annual effective dose rate due to the ingestion of vegetables in the crops using fertilizers at the agricultural zone of Hoc Mon, Ho Chi Minh City, Vietnam. The results show that there have not yet been signs of radioactive residues from using conventional fertilizers in agricultural land after a crop at the surveyed area and time. The radiological impact of surveyed vegetables was negligible to the public health.
