Abstract
Ionizing radiation is a valuable tool used for cancer treatment as well as for basic molecular research. More recent interest stems from a need to provide countermeasures against accidental or intentional exposure to radiation through nuclear devices. This chapter provides an overview of the biological effects of radiation and highlights models used to study radiation-induced damage and repair. In vitro and in vivo endpoints including DNA damage, cell survival, apoptosis, cytogenetic aberrations, oxidative stress, tumor response, and genomic instability are discussed. Appropriate use of these models will facilitate the advancement of radiation research as novel molecular mechanisms are elucidated.
