|---|---|---|---|
| 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. |

| alpha radiation | <physics, radiobiology> The most easily absorbable type of radiation, it consists of a stream of alpha particles, doubly ionised helium nuclei which are electrically charged and produce intense ionisation in matter. Alpha radiation can be deflected in electromagnetic fields. (09 Oct 1997) |
|---|---|
| annihilation radiation | The radiation resulting when a positron from beta positive decay comes to rest. It encounters an electron, and they annihilate each other and convert their rest mass into two 0.51-MeV gamma rays emitted in exactly opposite directions. (05 Mar 2000) |
| background radiation | <radiobiology> Level of environmental radation due to background sources. Background sources can be natural, such as cosmic rays and natural radioactive elements (principally radon, but including other elements such as isotopes of potassium (which people get substantial amounts of in foods like bananas)). They can also be man-made, such as from fossil-fuel combustion, everyday leakage from nuclear activities, and leftover from atmospheric nuclear weapons tests. Background radiation is usually distinguished from acute radiation, such as from medical X-rays, nuclear accidents, radioisotope therapy, or other short-term doses. The man-made contribution to background radiation is quite small compared to the natural contribution, medical uses dominate human exposure to acute radiation. (09 Oct 1997) |
| radiation | <radiobiology> Propagation of energy through space. In the context of this report, it is electromagnetic radiation (X-rays or gamma rays) or corpuscular radiation (alpha particles, electrons, protons, neutrons) capable of producing ionisation. (16 Dec 1997) |

| radiation biophysics | The study of the effects of radiation on cells, tissues, biomolecules, and living organisms. (05 Mar 2000) |
| radiation burn | A burn caused by exposure to radium, X-rays, atomic energy in any form, ultraviolet rays, etc. (05 Mar 2000) |
| 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) |
| beta radiation |
Radiation consisting of electrons or positrons emitted in many radioactive disintegrations, at speeds approaching the speed of light.

| beta radiation |
An electron (or a particle of equal weight to an electron but with a positive electrical charge) that is emitted from a radionuclide. It is less damaging than the same dose of alpha radiation but more penetrating. Beta radiation can be stopped by a thin sheet of metal or plastic.

| beta radiation |
streams of beta particles emitted by radioactive isotopes. Among the most common isotopes giving off beta radiation are radioactive carbon (C 10 ), radioactive phosphorus (Pas), radioactive strontium (Sr 90 ), and radioactive sulfur (S 35 ). Beta rays are essentially electrons traveling at high velocity, but the energy of beta particles is not so high as to allow them to penetrate very far into solid material. ...
