| 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. |

|---|---|---|---|
| 설명 | 1. 피부표면에서의 방사선의 공중선량으로 여기에는 1차방사선과 후방산란이 포함된다. 2. 피부에 흡수되는 선량. |

| PEL | Permissible Exposure Limit |
| MIRD | Medical Internal Radiation Dose |
| ICR | 3'-internal control region |
| maximum permissible dose | <radiobiology> Defined by the International Commission on Radiological Protection as the greatest dose of radiation which, in the light of present knowledge, is not expected to cause detectable bodily injury to a person at any time during his lifetime. This dose has been reduced with each Commission report. The MPD is given in terms of acute or chronic exposure of the whole body or of organs, systems, or regions of the body, and differs for persons who are occupationally exposed versus the public at large.

|---|---|
| maximum permissible exposure level | The highest level of exposure to a substance, usually noxious, in the environment or during diagnostic and therapeutic procedures, that a body can tolerate without injury. (12 Dec 1998) |
| permissible exposure limit | An occupational health standard to safeguard workers against dangerous contaminants in the workplace. (05 Mar 2000) |
| absorbed dose | The amount of energy absorbed per unit mass of irradiated material at the target site; in radiation therapy, the former unit for absorbed dose is the rad; the current (S.I.) unit is the gray. (05 Mar 2000) |
| air dose | The radiation dose, expressed in roentgens, delivered at a point in free air. Synonym: air dose. (05 Mar 2000) |
| bone marrow dose | The cumulative dose to the blood-forming organ from therapeutic or nuclear fallout irradiation; the presumed leukemogenic dose. (05 Mar 2000) |
| booster dose | A dose given at some time after an initial dose to enhance the effect, said usually of antigens for the production of antibodies. (05 Mar 2000) |
| breast dose in mammography | <radiology> 180 mrad / view -- mid-breast dose, guideline: less than 1 rad for 2-view exam (12 Dec 1998) |
| maintenance dose | In chemotherapy, systematic dosage at a level that maintains protection against exacerbation. (05 Mar 2000) |
| genetically significant dose | <physics, radiobiology> The genetically significant dose is that which, if received by every member of the population, would be expected to produce the same genetic injury to the population as do the actual doses received by the individuals irradiated. Thus, the genetically significant dose is the dose equivalent to the gonads weighted for the age and sex distribution in those members of the irradiated population expected to have offspring. The genetically significant dose is expressed in sieverts (or rem). Acronym: GSD (06 Aug 1998) |
| maximal dose | <pharmacology> The largest amount of a drug or physical procedure that an adult can take with safety. (05 Mar 2000) |
| median effective dose | The dose that produces the desired effect; when followed by a subscript (generally "ED50"), it denotes the dose having such an effect on a certain percentage (e.g., 50%) of the test animals; ED50 is the median effective dose, in radiation protection, the sum of the equivalent doses in all tissues and organs of the body weighted for tissue effects of radiation. The unit of effective dose is the sievert (Sv), epilation dose, the minimum amount of radiation sufficient to produce hair loss, usually in 10 to 14 days. (05 Mar 2000) |
| gonadal dose | The exposure dose to the male or female gonad, usually from incidental secondary radiation in diagnostic or therapeutic irradiation, or from whole-body irradiation. Synonym: gonadal dose. (05 Mar 2000) |
| gonad dose | The exposure dose to the male or female gonad, usually from incidental secondary radiation in diagnostic or therapeutic irradiation, or from whole-body irradiation. Synonym: gonadal dose. (05 Mar 2000) |
| minimal dose | <pharmacology> The smallest amount of a drug or physical procedure that will produce a desired physiologic effect in an adult. (05 Mar 2000) |
