AbstractAbstract
[en] The accumulation rate for different mushroom species varies, but there does not seem to be any clear correlation between the 137 Cs concentrations (Bq/kg fw) in the 1990-1991 mushrooms and the length of the ecological half-life. This is despite the fact that the highest concentrations have been measured in Cortinarius armillatus, the ecological half-life of which appears to be of the order of the physical T of 137 Cs, 30 y. All the Russula species have had low concentrations, although the half-lives are rather long 11-18 y. Lactarius trivialis has highers levels than the other analysed Lactarius species but there is no correlation with the half-lives. The type of forest stand does not seem to have any ef-fect on the caesium concentrations, except possibly for Rozites. (AU)

AbstractAbstract
[en] Since 1990 the project of radioactive and environmental contamination started in Guatemala. Studies about the radioactive contamination levels are made within the framework of this project. Cesium-137 has been an interest radionuclide, because it is a fission product released to the environment by the use of nuclear weapons and nuclear power plants accidents. The sampling consisted in collection of soil and grass in 20 provinces of Guatemala, one point by province, and it was made in 1990. The cesium-137 concentration in the samples, was determined by gamma spectrometry, using an hyper pure germanium detector. The results show the presence of radioactive contamination in soil and grass due to cesium-137, at levels that might be considered as normal. The levels found are not harmful for human health, and its importance is the fact that can be used as reference levels for the environmental radioactivity monitoring in Guatemala

AbstractAbstract
[en] This paper describes the profiles determination of cesium-137 concentration 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 0,89Ci. (author)

Apresenta-se neste trabalho, a tecnica utilizada para determinar os perfis de concentracoes de cesio-137 em funcao das profundidades, 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.

AbstractAbstract
[en] Seawater samples were collected from the Atlantic Ocean, in the vicinity of Ubatuba (Sao Paulo State - Brazil), acidified to pH 1 and stored in polyethylene containers. Cesium was precipitated with ammonium phosphomolybdate (AMP), synthesized in our laboratory. The elements potassium and rubidium present in the seawater are also coprecipitated by AMP and adequate decontamination of the cesium is made by preparing a column by mixing Cs-137 AMP precipitate and asbestos. The interfering elements were eluted with 1.0 M ammonium nitrate solution whereas cesium was eluted with 1.0 M sodium hydroxide solution. Cesium was reprecipitated by acidifying the solution with concentrated hydrocloric acid. The overall chemical yield of cesium was of 75%. (author)
