|---|---|---|---|
| 설명 | 빛의 전자자기파나 혹은 입자파(α, β, γ선)를 말하는데, 어떤 근원물질에서 생겨 방출된다. 이온쌍을 생성하는 고에너지 방사선(X-선과 감마선)을 말한다. 방사선하면, 주로 전리방사선을 의미한다. 이런 방사선을 이용하여, 가장 기본적인 방사선학적 검사를 할 수 있으며, 이외 치료에도 이용하고 있다. 각 방사선의 종류에 따라 조금씩 인체에 미치는 영향이 다르며, 이를 이용하여 각기 다르게 진단 및 치료에 이용한다. |

|---|---|---|---|
| 설명 | 방사선조사의 정도. 방사선생물학이나 인체의 방사선방호에서는 전리방사선의 양, 즉 선량이 문제가 된다. 방사선량에서도 국제단위계(SI)가 채용되어 국제방사선방호위원회(ICRP)의 권고에 따라서 다음의 여러 단위가 널리 사용된다. ① 흡수선량(absorbed dose). 물질의 단위질량이 방사선에 의해 받아들이는 에너지. 이 단위는 방사선 및 물질의 종류가 어떠한 것이더라도 사용할 수 있다. 국제단위는 J/kg이며 이것에 고유한 명칭으로 그레이(gray, 기호 Gy)가 부여된다. 1Gy=100라드(rad). ② 조사선량(exposure) 또는 공중선량. X선 또는 γ선에 한해서 사용된다. 국제단위는 C/kg. ③ 선량당량(dose equivalent). 방사선방호를 위해 사용되는 양. 기호는 H. H는 방사선의 종류와 에너지에 의해 생체에 주는 효과를 보정하는 선질계수(Q)와 그 밖의 인자(예를 들면 선량률, 방사성동위원소에 의한 내부피폭시에는 그 핵종의 체내분포 등)에 근거한 보정계수(N)를 흡수선량(D)에 곱한 것, 즉 H=D-Q-N. 또한 D의 단위를 Gy 또는 rad로 표시하였을 때 H의 단위를 각각 시베르트(sievert, 기호 Sv) 및 렘(rem)이라고 한다. 따라서 1 Sv=102rem. 일반적으로 단위시간당의 선량을 선량률(dose rate)이라고 한다. |

| 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. |

| 영문 | radiation therapy | 한글 | 방사선치료 |
|---|---|---|---|
| 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. |

Solar lamp, an argand lamp. Solar microscope, a microscope consisting essentially, first, of a mirror for reflecting a beam of sunlight through the tube, which sometimes is fixed in a window shutter; secondly, of a condenser, or large lens, for converging the beam upon the object; and, thirdly, of a small lens, or magnifier, for throwing an enlarged image of the object at its focus upon a screen in a dark room or in a darkened box.

Solar oil, a paraffin oil used an illuminant and lubricant. <mathematics> Solar phosphori, the sun, with the group of celestial bodies which, held by its attraction, revolve round it. The system comprises the major planets, with their satellites; the minor planets, or asteroids, and the comets; also, the meteorids, the matter that furnishes the zodiacal light, and the rings of Saturn. The satellites that revolve about the major planets are twenty-two in number, of which the Earth has one (see Moon), Mars two, Jupiter five, Saturn nine, Uranus four, and Neptune one. The asteroids, between Mars and Jupiter, thus far discovered (1900), number about five hundred, the first four of which were found near the beginning of the century, and are called Ceres, Pallas, Juno, and Vesta.

| solar blindness | Damage to the fovea centralis of the retina and the adjacent choroid due to the thermal action of infrared rays, consequent to sungazing or watching a solar eclipse without sufficient eye protection. See: photoretinopathy. Synonym: eclipse blindness, solar blindness. (05 Mar 2000) |
| solar cheilitis | Mucosal atrophy with drying, crusting, and fissuring of the vermillion border of the lower lip in older individuals, resulting from chronic exposure to sunlight; dysplastic (premalignant) changes are noted microscopically, analogous to solar keratosis. Synonym: actinic cheilitis. (05 Mar 2000) |
| solar dermatitis | A dermatitis in photosensitive persons caused by exposure to the sun's rays. (05 Mar 2000) |
| solar elastosis | Elastosis seen histologically in the sun-exposed skin of the elderly or in those who have chronic actinic damage. (05 Mar 2000) |
| solar energy | Energy transmitted from the sun in the form of electromagnetic radiation. (12 Dec 1998) |
| solar fever | A tropical disease caused by dengue virus (Arbovirus), that is transmitted by the bite of an infected mosquito of the genus Aedes). Four severity grades of the illness are seen: grade I (fever and constitutional symptoms), grade II (grade I plus spontaneous bleeding of skin, gums or gastrointestinal tract), grade III (grade II plus agitation and circulatory failure) and grade IV (profound shock). Grade I infection is seen most frequently in world travelers, where it is usually self-limited and rarely fatal. The other grades are referred to as dengue haemorrhagic fever and are often fatal. Dengue haemorrhagic fever appears to be an infection by one of the other dengue viruses. Prior immunity to a different dengue virus type appears to be important in the development of the more serious haemorrhagic form. Vaccines are available. Protection from mosquitoes is an important preventive measure. (27 Sep 1997) |
| solar ganglia | The largest and highest group of prevertebral sympathetic ganglia, located on the superior part of the abdominal aorta, on either side of the origin of the coeliac artery; contains sympathetic neurons whose unmyelinated postganglionic axons innervate the stomach, liver, gallbladder, spleen, kidney, small intestine, and ascending and transverse colon. H Synonym: ganglia coeliaca, semilunar ganglion, solar ganglia, Vieussens' ganglia, Willis' centrum nervosum. (05 Mar 2000) |
| solar keratosis | A skin lesion that is abnormally sensitive to the effects of ultraviolet light (sunlight). Thought to be a precancerous skin lesion that is more common in the fair-skinned or elderly individual. Approximately 20% of these skin lesions will develop into squamous cell carcinoma. Prevention includes the use of sun screen agents and the avoidance of drugs (for example tetracyclines) known to cause photosensitivity reactions. Usually a discreet slightly raised, red or pink lesion located on a sun exposed surface. Texture may appear as rough, gritty or scaly. Growths may be biopsied to look for cancer or removed via cryotherapy or electrical cautery. Some topical agents may be used to promote peeling. (27 Sep 1997) |

| solar radiation |
is heat energy from the sun, including the infrared, visible, and ultraviolet wavelengths. For heat island mitigation purposes, solar radiation is measured by American Society for Testing and Materials Standard E 1918, which provides for in-field use of a pyrometer to measure incoming and outgoing radiation.

| solar radiation |
The total electromagnetic radiation emitted by the sun. About 99.9 percent of its energy output falls within the wavelength interval from 0.15 microns to 4.0 microns, with peak intensity near 0.47 microns. About one-half of the total energy in the solar beam falls in the visible spectrum from 0.4 to 0.7 microns, and most of the other half falls in the near infrared, a small additional portion falling in the ultraviolet.
