Chromosome aberrations in survivors of Hiroshima and Nagasaki.

Description

Study of the number of aberrations in a sample of 100 cells in survivors of the atomic bombs dropped on Hiroshima and Nagasaki.

Usage

aberrations

Format

A data frame 1052 observations and three variables:

cells:

number of cells (out of 100) exhibiting chromosome aberrations

radiation:

approximate dose of radiation (in rads)

city:

city of residence

Note

The data are from Otake and Prentice (1984). The 400-999 and 1000+ rad groups have been combined here as both are quite sparse.
