| 영문 | standard error | 한글 | 표준오차 |
|---|---|---|---|
| 설명 | 통계용어로 표본 평균치 분포의 표준편차를 나타내는 것이다. 표본 평균치가 모집단의 평균치 주위에 산재하는 것은 표본 크기와 모집단의 표준편차(σ)에 의해 지배된다. 표준오차(SD)는 이론적으로 σ/√N으로 나타낸다. |

| 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. |

| 설명 | 어떤 다른 물질을 검출, 측정, 생성하기 위한 특정한 화학반응을 일으키는데 사용되는 방법. |

| standard | 1. A flag; colours; a banner; especially, a national or other ensign. "His armies, in the following day, On those fair plains their standards proud display." (Fairfax) 2. That which is established by authority as a rule for the measure of quantity, extent, value, or quality; especially, the original specimen weight or measure sanctioned by government, as the standard pound, gallon, or yard. 3. That which is established as a rule or model by authority, custom, or general consent; criterion; test. "The court, which used to be the standard of property and correctness of speech." (Swift) "A disposition to preserve, and an ability to improve, taken together, would be my standard of a statesman." (Burke) 4. The proportion of weights of fine metal and alloy established by authority. "By the present standard of the coinage, sixty-two shillings is coined out of one pound weight of silver." (Arbuthnot) 5. <botany> A tree of natural size supported by its own stem, and not dwarfed by grafting on the stock of a smaller species nor trained upon a wall or trellis. "In France part of their gardens is laid out for flowers, others for fruits; some standards, some against walls." (Sir W. Temple) 6. <botany> The upper petal or banner of a papilionaceous corolla. 7. <mechanics> An upright support, as one of the poles of a scaffold; any upright in framing. 8.
