On the cover: Examples of molecular biology methods for studying ionizing radiation damage to cells. The left panel illustrates chromosome painting technology for identifying each human chromosome and determining the number, location, and types of aberrations produced by ionizing radiation. The right panel illustrates the production of micronuclei that provide a measure of cytogenetic damage, which increases as a function of radiation dose.
