Description
Seventy nine samples, including soil and rock, were collected from the agrestic region of the State of Pernambuco, Brazil. The activity concentrations of 238U and 226Ra in the samples were determined by gamma-spectrometry using an HPGe detector. The concentrations of 238U were 22 Bq x kg-1 to 22 kBq x kg-1. The concentrations of 226Ra were 14 Bq x kg-1 to 17 kBq x kg-1. The 238U/226Ra ratios in the soil were 0.7 to 3.4 (arithmetic mean 1.7). The radiometric data were evaluated to explain 238U and 226Ra migration in the soil and the possible consequences to the environment. (author)
