| 영문 | radiation dose | 한글 | 방사선량 |
|---|---|---|---|
| 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 | dose | 한글 | 용량, 투여량, 방사선량 |
|---|---|---|---|
| 설명 | 1. 약제를 한 번 또는 하루에 사용하거나 복용하는 분량. 2. 물질이나 조직에 대한 방사선의 작용 정도를 나타내는 양. 즉, 방사선량이라는 개념은 어떤 한 점에 입사하는 방사선과 그 점 근처에 있는 물질에 대한 방사선의 물리적-화학적-생물학적 효과와의 관게를 정량적으로 나타내는 공통인 척도로서 생각된 것이다. 라드(rad)로 나타내는 흡수량, 렌트겐(R)으로 나타내는 조사 선량, 렘(rem)으로 나타내는 선량 당량으로 구분하여 쓴다. |

| 영문 | skin dose | 한글 | 피부선량 |
|---|---|---|---|
| 설명 | 1. 피부표면에서의 방사선의 공중선량으로 여기에는 1차방사선과 후방산란이 포함된다. 2. 피부에 흡수되는 선량. |

| atomic volume | The atomic weight of an element divided by its density in the solid state; the volume of the gram-atomic weight of a solid element. (05 Mar 2000) |
|---|---|
| blood volume | Volume of circulating blood. It is the sum of the plasma volume and erythrocyte volume. (12 Dec 1998) |
| blood volume determination | Method for determining the circulating blood volume by introducing a known quantity of foreign substance into the blood and determining its concentration some minutes later when thorough mixing has occurred. From these two values the blood volume can be calculated by dividing the quantity of injected material by its concentration in the blood at the time of uniform mixing. Generally expressed as cubic centimeters or liters per kilogram of body weight. (12 Dec 1998) |
| blood volume nomogram | A nomogram used to predict blood volume on the basis of the individual's weight and height. (05 Mar 2000) |
| cardiac volume | The volume of the heart, usually relating to the volume of blood contained within it at various periods of the cardiac cycle. The amount of blood ejected from a ventricle at each beat is stroke volume. (12 Dec 1998) |
| packed cell volume | <haematology> Measurement of the proportion of the blood occupied by the red blood cells. Normal values are 40-54% in males, 35-47% in females. (13 Nov 1997) |
| maximal expiratory flow-volume curve | <chest medicine> Curves depicting maximal expiratory flow in liters/second at each point of lung inflation (expressed in liters or percentage of forced vital capacity) during a forced vital capacity determination. Common abbreviation is mefv. (12 Dec 1998) |
| partial volume | The actual volume occupied by one species of molecule or particle in a solution; the reciprocal of the density of the molecule. (05 Mar 2000) |
| mean corpuscular volume | The average volume of red cells, calculated from the haematocrit and the red cell count, in erythrocyte indices. (05 Mar 2000) |
| residual volume | The volume of air remaining in the lungs at the end of a maximal expiration. Common abbreviation is rv. (12 Dec 1998) |
| volume | 1. A roll; a scroll; a written document rolled up for keeping or for use, after the manner of the ancients. "The papyrus, and afterward the parchment, was joined together [by the ancients] to form one sheet, and then rolled upon a staff into a volume (volumen)." (Encyc. Brit) 2. Hence, a collection of printed sheets bound together, whether containing a single work, or a part of a work, or more than one work; a book; a tome; especially, that part of an extended work which is bound up together in one cover; as, a work in four volumes. "An odd volume of a set of books bears not the value of its proportion to the set." (Franklin) 4. Anything of a rounded or swelling form resembling a roll; a turn; a convolution; a coil. "So glides some trodden serpent on the grass, And long behind wounded volume trails." (Dryden) "Undulating billows rolling their silver volumes." (W. Irving) 4. Dimensions; compass; space occupied, as measured by cubic units, that is, cubic inches, feet, yards, etc.; mass; bulk; as, the volume of an elephant's body; a volume of gas. 5. Amount, fullness, quantity, or calibre of voice or tone. <chemistry> Atomic volume, Molecular volume, the ratio of the atomic and molecular weights divided respectively by the specific gravity of the substance in question. <physics> Specific volume, the quotient obtained by dividing unity by the specific gravity; the reciprocal of the specific gravity. It is equal (when the specific gravity is referred to water at 4 deg C. As a standard) to the number of cubic centimeters occupied by one gram of the substance. Origin: F, from L. Volumen a roll of writing, a book, volume, from volvere, volutum, to roll. See Voluble. Source: Websters Dictionary (01 Mar 1998) |
| volume averaging | In computed tomography or magnetic resonance imaging, the effect of expressing the average density of a voxel as a pixel in the image; the greater the slice thickness, the more averaging is necessary, with loss in density resolution. (05 Mar 2000) |
| volume-controlled respirator | A respirator that provides a predetermined volume of gases during inhalation, with the pressure required to move that volume remaining variable, depending upon resistance. (05 Mar 2000) |
| volume element | See: voxel. (05 Mar 2000) |
| volume index | An indication of the relative size (e.g., volume) of erythrocytes, calculated as follows: haematocrit value, expressed as per cent of normal ÷ red blood cell count, expressed as per cent of normal = volume index. (05 Mar 2000) |
