| 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. |

| biological | Pertaining to biology. (18 Nov 1997) |
|---|---|
| biological agent | <microbiology> A disease-causing microorganism or virus, or other toxic biological matter, which is used as a weapon during war. (21 Mar 1998) |
| biological assay | <technique> Once a pharmaceutical protein is isolated from the cells in which it was grown, researchers perform tests to measure the protein's biological activity. It must maintain a certain minimal level of biological activity to be used for animal or clinical testing or, later, for market. Researchers also test to confirm that the isolated protein is identical to the desired protein. (21 Mar 1998) |
| biological assessment | A specific process required as part of an environmental assessment. An evaluation of potential effects of a proposed project on proposed, endangered, threatened, and sensitive animal and plant species and their habitats. (05 Dec 1998) |
| biological availability | The extent to which the active ingredient of a drug dosage form becomes available at the site of drug action or in a biological medium believed to reflect accessibility to a site of action. (12 Dec 1998) |
| biological chemistry | The scientific study of the chemistry of living cells, tissues, organs and organisms. (09 Oct 1997) |
| biological clock | <biology, physiology> An internal biological mechanism which controls certain biological rhythms and biocycles, such as metabolism, sleep cycles, photosynthesis. (21 Mar 1998) |
| biological clocks | The physiological mechanisms that govern the rhythmic occurrence of certain biochemical, physiological, and behavioural phenomena in plants and animals. The pineal gland, which receives input from the optic nerves and connects to the hypothalamus, may be the biological clock in humans. (12 Dec 1998) |
| biological coefficient | Rarely used term denoting the energy expended by the body at rest. (05 Mar 2000) |
| biological containment | <molecular biology> Refers to any number of methods to contain genetically engineered organisms by creating biochemical barriers to prevent them from growing outside the laboratory. In the case of bacteria and yeasts, genes in the organisms may be altered so that they need to have a supply of a nutrient that is normally found only in the laboratory. (21 Mar 1998) |
| biological control | <agriculture> The agricultural use of living things, such as parasites, diseases, and predators, to control or eliminate others, such as weeds and pests, rather than by using chemicals (herbicides and pesticides). (21 Mar 1998) |
| biological dressings | Human or animal tissue used as temporary wound coverings. (12 Dec 1998) |
| biological engineering | <agriculture> A type of artificial selection, the creation of plant or animal breeds that are agriculturally or industrially useful. Compare: natural selection. (21 Mar 1998) |
| biological factors | Compounds made by living organisms. They have biological or physiological activities. (12 Dec 1998) |
| biological half-life | <biochemistry, biology> This is the time required for one-half of the total amount of a particular substance in a biological system to be consumed or broken down by biological processes when the rate of removal is approximately exponential. Toxic chemicals with a long biological half-life (such as some pesticides) will tend to accumulate in the body and are, therefore, more likely to be harmful. A substance with a short biological half-life may still accumulate if a portion of it it becomes tightly bound to bone or other tissues, even if most of it is quickly cleared from the body.
