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

| age distribution | The frequency of different ages or age groups in a given population. The distribution may refer to either how many or what proportion of the group. The population is usually patients with a specific disease but the concept is not restricted to humans and is not restricted to medicine. (12 Dec 1998) |

| Bernoulli distribution | <statistics> The probability distribution associated with two mutually exclusive and exhaustive outcomes, e.g., death or survival. (14 Aug 2000) |
| binomial distribution | The probability distribution associated with two mutually exclusive outcomes; used to model cumulative incidence rates and prevalence rates. The bernoulli distribution is a special case of binomial distribution. (12 Dec 1998) |
| gaussian distribution | Continuous frequency distribution of infinite range. Its properties are as follows: 1) continuous, symmetrical distribution with both tails extending to infinity; 2) arithmetic mean, mode, and median identical; and 3) shape completely determined by the mean and standard deviation. (12 Dec 1998) |
| chi-square distribution | A distribution in which a variable is distributed like the sum of the the squares of any given independent random variable, each of which has a normal distribution with mean of zero and variance of one. The chi-square test is a statistical test based on comparison of a test statistic to a chi-square distribution. The oldest of these tests are used to detect whether two or more population distributions differ from one another. (12 Dec 1998) |
| multinomial distribution | Probability distribution associated with the classification of each of a sample of individuals into one of several mutually exclusive and exhaustive categories. (05 Mar 2000) |
| contagious distribution | <epidemiology> Same as an aggregated distribution. (05 Dec 1998) |
| poisson distribution | <epidemiology> The distribution which arises when parasites are distributed at random amongst hosts. (05 Dec 1998) |
| countercurrent distribution | A method of separation of two or more substances by repeated distribution between two immiscible liquid phases that move past each other in opposite directions. It is a form of liquid-liquid chromatography. (12 Dec 1998) |
| hospital distribution systems | Systems for delivering hospital supplies, food, laundry, etc., to patient care areas. (12 Dec 1998) |
| sex distribution | The number of males and females in a given population. The distribution may refer to how many men or women or what proportion of either in the group. The population is usually patients with a specific disease but the concept is not restricted to humans and is not restricted to medicine. (12 Dec 1998) |
| skew distribution | An asymmetrical frequency distribution; in biology and medicine it is usually a lognormal distribution. (05 Mar 2000) |
| negative binomial distribution | <epidemiology> A distribution which is parameterised by a mean m and an aggregation parameter k which is large when aggregation is small; in fact as k becomes large, the negative binomial distribution approximates the Poisson distribution. (05 Dec 1998) |
| nitrogen distribution | Determination of the distribution of nitrogen in the urine among the various constituents. Synonym: nitrogen distribution. (05 Mar 2000) |
| normal distribution | Continuous frequency distribution of infinite range. Its properties are as follows: 1) continuous, symmetrical distribution with both tails extending to infinity; 2) arithmetic mean, mode, and median identical; and 3) shape completely determined by the mean and standard deviation.
