Biological effects of radiation
1980Publisher Summary This chapter describes the biological effect of radiation on cells, tissues, organs, and individuals. The units of measurement of radiation and its effect are identified, and the philosophy and practice of setting limits on exposure are reviewed.

Effects of radiation on the lung
Current Opinion in Pulmonary Medicine, 1996Since the beginning of the twentieth century, radiation has been employed as a tool to cure or palliate malignancy. Unfortunately, soon after its discovery, the harmful effects of radiation were recognized as well. As our understanding of the physiologic responses to radiation increases, we can refine the routes of delivery and dosages of radiation ...

Publisher Summary This chapter discusses the genetic effects of radiations that throw light on the mechanisms involved or upon the nature of the genetic changes and of the gene itself. The genetically effective radiations are of two kinds: ionizing and nonionizing.

The decrease of NADH following ionizing irradiation was investigated over a concentration range from 10−3 to 5 x 10−8 M. The nonexponential function of the curve was discussed. TheG-values were calculated for different starting concentrations. The results were compared with theG-values for NADH following irradiation under enzymatic equilibrium ...

The Biological Effects of Radiations
Annual Review of Physiology, 1951The study of the biological effects of ionizing radiations has increased enormously in the past few years, largely because of the development of atomic energy, with its attendant hazards and potentialities. This interest is reflected in the large number of papers published in this general field dur ing the past year.

Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1966, 1966
The effects of exposure to high-energy radiation can produce both transient and permanent changes in plastic materials. The former are evidenced by such behavior as induced electrical conductivity and thermoluminance; the latter by changes in chemical structure which in their turn produce marked physical changes, both electrical and mechanical.

New England Journal of Medicine, 1958
IN keeping with the times, a chief interest of physicians should center about the ionizing radiations. Yet it may not be amiss to present a synopsis of ocular effects from portions of the electromagnetic spectrum in addition to those of the ionizing portion, and to point out how anatomic peculiarities of the eye make this organ especially vulnerable to

Effects of Ultraviolet Radiation
Medical Clinics of North America, 1990Ultraviolet radiation from high-intensity sources has well-known acute effects on the eye and skin, consisting primarily of photokeratoconjunctivitis and sunburn, which are enhanced in the presence of photosensitizing agents. Long-term elevated exposure to low-level ultraviolet radiation is also responsible for an increased risk of squamous- and basal ...

Ionizing radiation produces its deleterious biologic effects by both direct (DNA strand breaks) and indirect processes (formation of free oxygen radicals). Mitotically active cells are more susceptible to the detrimental effects of ionizing radiation.
