## Rongelap data

### Description

This data-set was used by Diggle, Tawn and Moyeed (1998) to illustrate the model-based geostatistical methodology introduced in the paper. discussed in the paper. The radionuclide concentration data set consists of measurements of gamma-ray counts at 157 locations.

### Usage

    data(rongelapUTM)

### Format

A SpatialPolygonsDataFrame, with columns `count` being the radiation count and `time` being the length of time the measurement was taken for. A UTM coordinate reference system is used, where coordinates are in metres.
