| 영문 | radiation therapy | 한글 | 방사선요법 |
|---|---|---|---|
| 설명 | X선, γ선의 전자방사선이나 전자선, 양자선, 중성자선 등의 입자방사선을 이용해, 주로 악성 종양 치료를 목적으로 하는 치료법이다. 암세포가 주위의 정상세포보다도 방사선 감수성이 높은 점을 이용하여, 정상세포의 손상을 가능한 한 최소로 억제하면서 암세포를 파괴한다. 사용되는 방사선에는 밀봉소선원에서 나오는 γ선, 직선가속기에서 얻어지는 고에너지 X선과 전자선, 텔레코발트장치에 의한 60Co의 γ선과, 베타트론에 의한 전자선, 사이크로트론에서 얻어지는 양자선, 중성자선 등이 있다. |

|---|---|---|---|
| 설명 | 방사선의 살균효과나 세포를 죽이는 효과를 치료에 이용하는 방법으로, 좁은 의미로 암의 방사선치료를 의미한다. 암에 대한 방사선치료는 암세포를 죽이는데 효과가 큰 베타선을 주로 사용한다. 하지만, 이런 방사선치료는 정상세포에도 큰 영향을 끼쳐 이에 따른 기능의 장애를 가져올 수 있다. 따라서 방사선치료에 있어서는 단지 그 암세포에 대한 작용뿐만 아니라, 정상세포에 대한 작용도 고려하여 시행한다. |

| radiation caries | Caries of the cervical regions of the teeth, incisal edges, and cusp tips secondary to xerostomia induced by radiation therapy to the head and neck. (05 Mar 2000) |

| radiation cataract | A cataract caused by excessive or prolonged exposure to ultraviolet rays, X-rays, radium, beta rays, gamma rays, heat, or radioactive isotopes. (05 Mar 2000) |
| radiation chemistry | The science concerned with the effects of ionizing or nuclear radiation on chemical reactions or materials. (05 Mar 2000) |
| radiation chimera | An organism whose body contains cell populations of different genotypes as a result of the injection of foreign cells into it after it has received sufficient ionizing radiation to destroy the mature host cells which would otherwise reject the injected cells. (12 Dec 1998) |
| radiation damage, bulk | <radiobiology> General term describing changes in chemical and/or metallurgical properties of structure components of fusion reactor caused by atomic displacement and nuclear transmutation events occuring as a result of exposure to a radiation environment (such as the neutrons emitted from a fission or D-T fusion reactor). (09 Oct 1997) |
| radiation damage, surface | <radiobiology> General term describing damage to the surface of the containment structure which directly interfaces with the thermonuclear plasma, includes such phenomena as radiation blistering, charged-particle (or neutron) sputtering, and spallation or exfoliation of layers of the surface. (09 Oct 1997) |
| radiation dermatosis | Skin changes at the site of ionizing radiation, particularly erythema in the acute stage, temporary or permanent epilation, and chronic changes in the epidermis and dermis resembling actinic keratosis. (05 Mar 2000) |
| radiation fibrosis | The formation of scar tissue as a result of radiation therapy to the lung. (12 Dec 1998) |
| radiation inactivation | The technique of inactivating proteins in freeze dried (lyophilised) preparations using high energy particles (e.g. Electrons). One high energy particle can apparently inactivate all of the components of a multisubunit polypeptide, the method is therefore used to determine the molecular weight of functional oligomers. (18 Nov 1997) |
| radiation injuries | Harmful effects of non-experimental exposure to ionizing or non-ionizing radiation in chordates. (12 Dec 1998) |
| radiation injuries, experimental | Harmful effects of exposure to ionizing or non-ionizing radiation produced experimentally in chordates. (12 Dec 1998) |
| radiation, ionizing | Electromagnetic or corpuscular radiation capable of producing ions, directly or indirectly, in its passage through matter. The wavelengths are equal to or smaller than those of short (far) ultraviolet radiation and include gamma and X-rays and high-energy elementary particles. (12 Dec 1998) |
| radiation leukaemia virus | A murine leukaemia virus isolated from radiation-induced lymphomas in c57bl mice. It is leukemogenic, thymotrophic, can be transmitted vertically, and replicates only in vivo. (12 Dec 1998) |
| radiation monitoring | The observation, either continuously or at intervals, of the levels of radiation in a given area, generally for the purpose of assuring that they have not exceeded prescribed amounts or, in case of radiation already present in the area, assuring that the levels have returned to those meeting acceptable safety standards. (12 Dec 1998) |
| radiation myelitis | Damage to the spinal cord from exposure to X-rays or other high energy radiation; usually radiation myelitis. Synonym: radiation myelitis. (05 Mar 2000) |
