Description / Table of Contents:
Advances in Radiation Biology, Volume 6: Effects of Low Dose and Low Dose Rate Radiation examines the biological effects of low dose and low dose rate ionizing radiation on a broad scale, covering various articles from microdosimetry to analyses of human responses. Estimates of the effects on humans from low doses or from sustained exposures to low dose rates of ionizing radiations are of critical importance for the assessment of radiation risks under occupational and environmental conditions. This book consists of such knowledge that is essential for radiation protection and governmental regulatory activities pertaining to radiation exposure. This volume is intended for radiobiologists, radiation epidemiologists, radiation physicists, radiation safety personnel, health officials, and individuals involved in regulatory activities.
