British Medical Bulletin, 1946
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.

Radiation effects on development
Birth Defects Research Part C: Embryo Today: Reviews, 2007AbstractIt has been widely reported that prenatal exposure to ionizing radiation can interfere with embryonic and fetal development, depending on dose and gestational age in which exposure occurs. According to several studies on animal models, different well‐defined stages during prenatal life can be distinguished in relation to teratogenic effects ...

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.

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 ...

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

Advances in Space Research, 1986
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 ...

Radiation Effects on Biomembranes
1974Radiation damage can be produced by directly-ionizing radiation, such as α particles, β particles, protons, etc., indirectly by γ and x rays, which cause ejection of fast electrons from target atoms, as well as by neutrons which generate recoil protons and other nuclei. In all cases the resulting charged particles excite or ionize other molecules in so-

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.
