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 ...

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 ...

Radiation Research Supplement, 1960
Results are reported from a number of studies of radiation effects in gels. Topics discussed include the use of gel systems as radiation dosimeters, and the nature of the gel effect. 34 references. (C.H.)

The radiation protection guidelines of the National Aeronautics and Space Administration (NASA) are under review by Scientific Committee 75 of the National Council Protection and Measurements. The re-evaluation of the current guidelines is necessary, first, because of the increase in information about radiation risks since 1970 when the original ...

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 (

Radiology, 1952
Several recent articles (3–7) have again called attention to the importance of radiation effects upon growing and adult bone. Whereas it was formerly thought that adult bone is one of the most radioresistant of normal tissues, it is now recognized that it is the soft-tissue components of the bone, such as the terminal blood vessels of the haversian and

The International Journal of Applied Radiation and Isotopes, 1966
Abstract Irradiation of pectins by γ-rays causes the decomposition of molecules, which is observed as an extensive decrease of the specific viscosity of the solutions. The molecular weight also decreases by a factor in the range of 10 2 . The decomposition is intensified when solutions of pectin in water are irradiated.

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.

Journal of Dental Research, 1972
Rats subjected to 600 R total body radiation were studied. Changes in the epiphyseal cartilage were examined from the morphologic and enzymatic aspects, and were correlated with changes in the marrow contents and underlying bone. Changes noted were specific for radiation damage and were not caused by nutritional deficiencies.

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 ...
