The data are are the cesium concentrations (in Bq/kg) in soil and in mushrooms at 17 wooded locations in Umbria, Central Italy, from August 1986 to November 1989. Researchers wished to investigate the cesium transfer from contaminated soil to plants after the Chernobyl nuclear power plant accident in April 1986 by describing the distribution of the mushroom concentration as a function of soil concentration.
A data frame with 17 observations on the following 2 variables.
the cesium concentration in mushrooms, Bq/kg
the cesium concentration in soil, Bq/kg
