| 영문 | beta human chorionic gonadotropin | 한글 | 베타 사람융모성 생식샘자극호르몬 |
|---|---|---|---|
| 설명 | 태반세포에서 만들어지는 호르몬. 기능은 임신의 초기에 황체(원래 난자를 싸고 있던 세포들이 배란이 일어나서 난자가 빠져나간 후 주머니 모양을 이룬 것. 임신초기에 임신의 유지에 필요한 호르몬을 생성한다)의 유지에 기여하고, 태아의 고환조직에서 남성호르몬이 분비되는 것을 촉진시킨다. 또 이것은 임신초기의 임산부의 소변에서 많은 양이 검출되므로 이것을 이용해서 임신의 여부를 손쉽게 조사할 수가 있다. |

|---|---|---|---|
| 설명 | 방사성 원자핵이 β붕괴함에 따라 방출되는 방사선. 원자에 정상보다 많거나 적은 중성자나 양자를 가지고 있는 경우에는 원자가 안정되기 위하여 붕괴가 세가지 방법으로 생긴다. 이중 중성자가 하나의 전자를 내고 양성자가 되는 변화를 거치면서 나오는 전자선이다. 그 실체는 고속의 전자 또는 양전자이며 최대 에너지는 105-107eV. 투과력 및 이온화 작용은 α선과 γ선의 중간 정도이다. |

| decay | To pass gradually from a sound, prosperous, or perfect state, to one of imperfection, adversity, or dissolution; to waste away; to decline; to fail; to become weak, corrupt, or disintegrated; to rot; to perish; as, a tree decays; fortunes decay; hopes decay. "Ill fares the land, to hastening ills a prey, Where wealth accumulates and men decay." (Goldsmith) Origin: OF. Decaeir, dechaer, decheoir, F. Dechoir, to decline, fall, become less; L. De- + cadere to fall. See Chance. 1. Gradual failure of health, strength, soundness, prosperity, or of any species of excellence or perfection; tendency toward dissolution or extinction; corruption; rottenness; decline; deterioration; as, the decay of the body; the decay of virtue; the decay of the Roman empire; a castle in decay. "Perhaps my God, though he be far before, May turn, and take me by the hand, and more - May strengthen my decays." (Herbert) "His [Johnson's] failure was not to be ascribed to intellectual decay." (Macaulay) "Which has caused the decay of the consonants to follow somewhat different laws." (James Byrne) 2. Destruction; death. 3. Cause of decay. "He that plots to be the only figure among ciphers, is the decay of the whole age." (Bacon) Synonym: Decline, consumption. See Decline. Source: Websters Dictionary (01 Mar 1998) |

| decay constant | <physics, radiobiology> The fraction of the amount of a radionuclide that undergoes transition per unit time. Formally: Lamda=dP/dt Where dP is the probability of a given nucleus undergoing spontaneous nuclear transition in the time interval dt. (16 Dec 1997) |
| decay modes | <radiobiology> Different pathways for decay of radioactive nuclei. The decay modes for a given unstable state can include beta emission (negative = electron, positive = positron), electron capture, alpha emission, fission, and gamma emission. (13 Nov 1997) |
| decay theory | A theory of forgetting based on the premise that an engram or memory trace dissipates progressively with time during the interval when it is not activated. (05 Mar 2000) |
| tone decay test | The sounding of a continuous tone at threshold for 1 min; if the intensity must be increased by more than 5 dB for continued perception, it may be a sign of retrocochlear damage. (05 Mar 2000) |
| exponential decay | <epidemiology> A decline in which the rate of decay is always proportional to the amount of material remaining; the constant of proportionality is the rate constant. (05 Dec 1998) |
| free induction decay | In magnetic resonance imaging, the decay curve that is detected by the radiofrequency coil after the application of an excitation pulse, without additional pulses (free). (05 Mar 2000) |

| beta decay |
The process of radioactive decay in which a neutron loses a beta particle, which is physically identical to an electron. This increases the atomic number of the atom by one by turning the neutron into a proton. The atom's atomic mass number stays the same because the total number of protons and neutrons remain the same. The most common form of radioactive decay.
