Resumo: | The objective of this work was to determine the impact of phosphogypsum application on 226Ra and 228Ra activities in the soil and on their accumulation in soybean grains. A field experiment was carried out in Paraná state, Brazil, on a loamy Typic Hapludox, under no-till system, with increasing phosphogypsum rates: 4, 8, and 12 Mg ha-1. Gamma-ray spectrometry was carried out using HPGe detectors with 45 and 10% relative efficiencies, for soybean grains and soil, respectively. No increment of 226Ra and 228Ra activities was observed due to the increase in phosphogypsum rates in the soil, and a small reduction was noticed in the grains. Average values found for 226Ra and 228Ra activities were 37 and 57 Bq kg-1 in the soil and 1.44 and 3.19 Bq kg-1 in soybean grains. The application of phosphogypsum for no-till soybean production is a safe practice regarding the risks of radiation damage to human health. |

O objetivo deste trabalho foi determinar o impacto da aplicação superficial de gesso agrícola sobre as atividades de 226Ra e 228Ra no solo e sobre seu acúmulo nos grãos de soja. Foi realizado um experimento de campo no Estado do Paraná, Brasil, em um Latossolo Vermelho de textura média, sob sistema de plantio direto, com doses crescentes de gesso agrícola: 4, 8 e 12 Mg ha-1. A espectrometria de raios gama foi realizada com uso de detectores de HPGe, com eficiência relativa de 45 e 10%, para os grãos de soja e para o solo, respectivamente. Nenhum incremento nas atividades de 226Ra e 228Ra foi verificado no solo em razão do aumento das doses de gesso agrícola, e uma pequena redução foi observada nos grãos. Os valores médios de atividade encontrados para o 226Ra e 228Ra foram 37 e 57 Bq kg-1 no solo e 1,44 and 3,19 Bq kg-1 nos grãos de soja. A aplicação de gesso agrícola na soja produzida em plantio direto é uma prática segura quanto aos riscos de exposição e danos da radiação para a saúde humana.
