Determination of the cesium-137 concentration profile in the main contamination focus of the radiological accident at Goiania-GO, Brazil
Description
The purpose of this paper is to describe the method used to determinate cesium-137 concentration profiles measured in function of depth and applied in seven areas considered as the main contamination focus. Since november 14th to december 17th 1987, 125 soil drillings were made and a total of 740 soil samples were prepared. Obtained data allowed to calculate the soil volume to be removed from contaminate areas. It was verified that after remotions the remaining activity was approximately 0,89 Ci. (author)
Abstract (Portuguese)
Apresenta-se neste trabalho, a tecnica utilizada para determinar os perfis de concentracoes de cesio-137 em funcao das produndidades, em sete locais, considerados focos principais. Executaram-se 125 furos de amostragem de solo, totalizando 740 amostras, no periodo de 14 de novembro a 17 de dezembro de 1987. Os dados obtidos forneceram subsidios para calcular o volume de solo a ser removido dos locais contaminados. Verificou-se que apos as remocoes, a atividade residual foi de aproximadamente 0,89 Ci.
