title: Recent developments in fundamental radiobiology.
abstract: Recent developments in three areas of radiobiology of interest to radiotherapy are reviewed. These areas are: experiments designed to evaluate the effect of local tissue oxygenation, tumor volume and fractionation on the dose required to control murine mammary carcinoma; experiments designed to investigate the oxygen effect in cells which are exposed to extremely short pulses of radiation; experiments designed to examine the possibilities for negative pi mesons in radiotherapy.
