The biological effects of radiation
International Journal of Risk and Safety in Medicine, 1993Nuclear medicine offers many diagnostic possibilities for which there are no adequate alternatives. The growing contribution of nuclear procedures to diagnostic medicine, however, has an additional effect: the radiation on normal tissues. Accurate estimations of the radiation dose and the related risks is required to weigh the advantages against the ...

Effects of Radiations on the Heart
The British Journal of Radiology, 1960A clinical and electrocardiographic study of the effects of radiations on the heart is prefaced by a critical review of the clinical and experimental literature. Part I. General review Pathological evidence both from man and from experimental animals indicated the inherent radiosensitivity of the heart to be low; structural changes were described in ...

Effects of Ultraviolet Radiation
Annual Review of Physiology, 1946Interest in obtaining a better understanding of biological effects of ultraviolet radiation has been stimulated to a great extent dur ing the last few years by the wide application that ultraviolet has found as a therapeutic agent (1) in genetics (120), in the study of the fundamental structure of living cells (23), and in its wide use in aerobiology (

The Paradox of Radiation's Effects
Science, 2005Paradoxes are very often indicative of our inadequate insight into natural phenomena rather than being features of the phenomena themselves. C. Dissanayake's description of the intimate entanglement of human health with mankind's local material basis (“Of stones and health: medical geology in ...

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.

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 ...

The effects of radiation on biologic systems as manifested through genetic changes have been reviewed. The use of x-radiation by the health professions represents the largest contribution of radiation dose to the people of the United States. It is apparent that the genetic effect of radiation results in the production of chromosomal aberrations and ...

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

Here we discuss the low risk of radiation-related complications after Leksell radiosurgery, as well as its diagnosis and management. Using multimodality imaging in the context of clinical suspicion of radiation injury clinicians can now start management with agents designed to reduce the progression of radiation vasculopathy.

Clinics in Plastic Surgery, 1993
Radiation therapy can be used to maintain useful vision by avoiding enucleation to obtain local control in ocular malignancies. This can be accomplished by a variety of radiation techniques, which are prescribed according to the extent of tumor involvement.
