Book Description
Rats and dogs were exposed to fast neutron and to 250 kvp X irradiation (rats) or to 1000 kvp X irradiation (dogs). Animals were exposed bilaterally to the whole body and depth dosimetry evaluated in each case. In the rat, 7 days after irradiating, bioelectric activity is markedly reduced from normal in stomach but not at the lower gastrointestinal level. An RBE value of 2-3 can be established for delayed reduction in gastric bioelectric activity, and this effect is readily demonstrated at neutron doses of 160 rad (1st collision). In the dog, 3 days after irradiating, the unidirectional transfer rates from plasma-to-lumen are decreased for sodium and for water. This occurs after X-irradiation at 1200 r (air dose) and after neutron irradiation at either 300 rad or 600 rad (1st collision). However, at 600 r X-irradiation doses (air) these transfer rates do not show a decrease, and tend in the opposite direction. An RBE value lying between 2 and 6 can be inferred for the delayed reduction in plasma-to-lumen transfers. (Author).

Book Description
The updated Sixth Edition of this popular text will remain the first choice for those who need current, clinically relevant information on how radiation affects the human body. Written by practicing, active radiobiologists, the book brings together basic laboratory research and practical, clinical applications. The easy-to-read text and informative illustrations ensure comprehension, and summaries at the end of each chapter facilitate quick review. The first section covers topics applicable to diagnostic radiology, nuclear medicine, and radiation oncology; the second section offers material specifically for radiation oncologists. This edition includes new material about doses and risks in interventional radiology and cardiology.
