to eradicate a variety of malignant diseases involving the thorax, including primary lung …

The degenerative and fibrotic changes produced by irradiation in all tissues are of especial
significance when their presence interferes with vital functions. One of those in which this …

The history of radiation research shows that clinical problems give rise to experimental
studies and that, in turn, radiobiological findings contribute to the improvement of …

T he fundamental ability to successfully treat any neoplasm ultimately depends on the
therapeutic ratio, ie, the ability to sterilize the tumor while sparing normal tissues. There are …

More than 40 cell types are found in the lung, most of which are considered to be relatively
radioresistant. However, the lung is unable to tolerate large radiation doses since the organ …

Groups of LAF1 mice were given thoracic irradiation using 60 Co γ-rays at dose-rates of 0.05
