| 설명 | 원자에 정상보다 과다, 과소한 중성자나 양자를 가지고 있는 경우에 원자가 안정되기 위해서 붕괴가 생긴다. 이런 붕괴에는 다음과 같은 3가지 방법이 있다. 알파－붕괴는 알파입자를 방출하여 안정되는 법, 즉 원자번호는 2씩 감소하고 질량수는 4씩 감소한다. 알파입자란 알파붕괴에 의해서 생기는 헬륨의 핵과 같은 입자를 말한다. |

| 설명 | 태아의 간조직이나 소화기관에서 만들어지는 단백질. 태아기나 임산부에서 정상적으로 존재한다. 그러나 간암세포나 생식세포에 관련된 종양에서도 만들어져 이런 질병이 존재할 때에는 임산부나 태아가 아니더라도 조직이나 혈액에 나타나게 된다. 임상적으로는 간암이나 생식세포 종양의 발견과 치료효과 판정에 이용되고, 또 임신 16~18주에 산모의 혈액에서 이단백질의 양을 측정하여 태아의 비정상적인 발달을 발견할 수 있다. |

| radioactive decay | <physics> The process by which a spontaneous change in nuclear state takes place. This process is accompanied by the emission of energy in various specific combinations of electromagnetic and corpuscular radiation and neutrinos. (16 Dec 1997) |

| 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 accelerating factor | <biochemistry, protein> Plasma protein that regulates complement cascade by blocking the formation of the C3bBb complex (the C3 convertase of the alternate pathway). Widely distributed in tissues but deficient in paroxysmal nocturnal haemoglobinuria. (18 Nov 1997) |
| 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) |
