In the acute phase there is vascular damage, congestion, oedema, and mononuclear cell infiltration; in the subacute phase the alveolar walls are infiltrated with mononuclear inflammatory cells and fibroblasts; in the chronic phase, alveolar fibrosis and capillary sclerosis take place.

| radiation poisoning | A systemic condition caused by substantial whole-body irradiation, seen after nuclear explosions or accidents, rarely after radiotherapy. Manifestations depend on dose, ranging from anorexia, nausea, vomiting, and mild leukopenia, to thrombocytopenia with haemorrhage, severe leukopenia with infection, anaemia, central nervous system damage, and death. Synonym: radiation poisoning. (05 Mar 2000) |
| radiation risks | The risks to health posed by exposure to radiation. Exposure comes from both natural sources and from man-made ones (medical and occupational). See: background radiation.Because any amount of radiation may cause cellular mutations, considerable effort has been made by government and independent researchers to establish exposure guidelines. In most cases, natural sources account for the bulk of received radiation, with artificial sources adding only a small percentage to the average annual dose. Public perception of the hazards of radiation is often at odds with scientific positions on the matter. In part, equivocal research results (as in attempts to assess the added cancer risk posed by mammograms) contribute to public fears. Some psychological studies have concluded that whether or not public fears of nuclear power plants and other radiation sources are justified, the added stress caused by such fears in itself constitutes a threat to health that should be addressed.

| radiation sickness | A systemic condition caused by substantial whole-body irradiation, seen after nuclear explosions or accidents, rarely after radiotherapy. Manifestations depend on dose, ranging from anorexia, nausea, vomiting, and mild leukopenia, to thrombocytopenia with haemorrhage, severe leukopenia with infection, anaemia, central nervous system damage, and death.

| coherent radiation | <physics> Any form of radiation in which the phase relationship between sections of the wave at different locations is not random (or incoherent!). Typical example is a laser beam, in which the phase is more or less uniform across the beam and changes along the beam in accordance with the wavelength. Radiation in which the photons tend to correlate with one another, rather than being randomly distributed. (09 Oct 1997) |
| Wernicke's radiation | The massive, fanlike fibre system passing from the lateral geniculate body of the thalamus to the visual cortex (striate or calcarine cortex, area 17 of Brodmann); the fibres follow the retrolenticular and sublenticular limbs of the internal capsule into the corona radiata but they curve back along the lateral wall of the temporal and occipital horns of the lateral ventricle to the striate cortex on the medial surface and pole of the occipital lobe.

| radiation therapy |
Radiation therapy (or radiotherapy) is the medical use of ionizing radiation as part of cancer treatment to control malignant cells (not to be confused with radiology, the use of radiation in medical imaging and diagnosis). Although radiotherapy is often used as part of curative therapy, it is occasionally used as a palliative treatment, where cure is not possible and the aim is for symptomatic relief. ...

| radiation absorbed dose |
A measurement of the energy deposited in any material by ionizing radiation. One rad is equal to the absorption of 100 ergs of energy in every gram of the material exposed totheradiation.

| radiation therapy |
Radiation therapy (also called radiotherapy) uses high-energy radiation from x-rays and other sources to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external radiation therapy) or from materials that produce radiation (radioisotopes) that are placed inside the body in the area where the cancer cells are found (internal radiation therapy, implant radiation, or brachytherapy). ...
