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 ...

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.

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.

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 ...

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

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.
