ex0818: Chernobyl Fallout

In Sleuth2: Data Sets from Ramsey and Schafer's "Statistical Sleuth (2nd Ed)"

Description

One of the most dangerous contaminants deposited over European countries following the Chernobyl accident in April 1986 was radioactive cesium. To study cesium transfer from contaminated soil to plants, researchers collected soil samples and samples of mushroom mycelia from 17 wooded locations in Umbria, Central Italy, from August 1986 to November 1989. The data are measured concentrations (Bq/kg) of cesium in the soil and in the mushrooms.
