| 설명 | 방사성을 띠는 핵물질을 이용하여 의학에 응용하는 학문. 대개 인체에 큰 해가 없는 방사선물질을 사용하며, 반감기가 짧아 사용후에도 큰 해가 없다. 이런 핵의학적 물질을 이용한 핵의학적 진단의 가장 큰 장점은 생체내에서 일어나는 그 기관의 실제적인 기능을 알아볼 수 있다는 데 있다. 흔히 접하는 X-선을 이용한 진단방법은 단지 그 순간만의 영상을 접하여 실제로 보이는 부위가 얼마나 기능을 수행하는지 알 수 없는 단점이 있으나, 핵의학에서는 실제적인 기능의 정도에 따라 영상이 나오게 되므로 기능판별에 아주 유리하다. 하지만, 정확한 판별력이 있는 영상을 얻기에는 부족하다. 또한 핵의학은 진단외의 치료에도 사용되는데, 예를 들어 갑상샘종양의 경우 여러 곳에 이미 전이가 되어 있을 경우 방사선핵종을 이용하여 다른 곳에 큰 부작용없이 치료가 가능하다. |

| 설명 | 다른 말로 MRI=Magnetic Resonance Imaging 자기공명영상이라고도 한다. 인체의 장기나, 병적인 모양, 종양의 위치, 림프절의 비대 등에 대한 진단을 내리기 위해 시행하는 방사선학적인 검사방법이다. 현재 많이 쓰이고 있는 컴퓨터단층촬영(CT=computerized tomography)과는 다른 방법으로 시행하며, 그 해상도가 컴퓨터단층촬영보다는 뛰어나 비록 고가이긴 하지만, 많이 쓰이고 있다. 또한 인체에 무해하고, 여러 가지 면(plane)에서 사람을 단층시켜 볼 수 있다. 단점은 심장박동기를 설치한 사람이나, 주위에 자장을 띠는 물체를 몸에 지니고 있는 중환자 등에서는 이용할 수 없고, 복부장기에 대한 진단에는 컴퓨터단층촬영보다 떨어지는 것으로 되어 있다. |

| nuclear atom | <physics, radiobiology> A concept or model of the atom characterised by the presence of a small, massive nucleus at its centre. (05 Mar 2000) |

| activated atom | An atom possessing more than normal energy as a result of input of energy. See: excited state. Synonym: excited atom. (05 Mar 2000) |

| atom | <chemistry, physics, radiobiology> A particle of matter indivisible by chemical means. It is the fundamental building block of the chemical elements. The elements, such as iron, lead and sulphur, differ from each other because they contain different kinds of atoms. There are about six sextillion (6 followed by 21 zeros or 6 x 1021) atoms in an ordinary drop of water. According to present day theory, an atom contains a dense inner core (the nucleus) and a much less dense outer domain consisting of electrons in motion around the nucleus. Atoms are electrically neutral. (16 Dec 1997) |
| Bohr's atom | A concept or model of the atom in which the negatively charged electrons move in circular or elliptical orbits around the positively charged nucleus, energy being emitted or absorbed when electrons change from one orbit to another. (05 Mar 2000) |
| radioactive atom | <chemistry, physics> An atom with an unstable nucleus, which emits particulate or electromagnetic radiation (radioactive emission) to achieve greater stability. See: radionuclide, half-life, Becquerel. (05 Mar 2000) |
| recoil atom | The remainder of an atom from which a nuclear particle has been emitted or ejected at high velocity; the remainder recoils with a velocity inversely proportional to its mass. (05 Mar 2000) |
| central atom | <physics> The atom to which the other atoms are bonded in a small molecule. (09 Oct 1997) |
| spectrometry, mass, fast atom bombardment | A mass spectrometric technique that is used for the analysis of a wide range of biomolecules, such as glycoalkaloids, glycoproteins, polysaccharides, and peptides. Positive and negative fast atom bombardment spectra are recorded on a mass spectrometer fitted with an atom gun with xenon as the customary beam. The mass spectra obtained contain molecular weight recognition as well as sequence information. (12 Dec 1998) |
| stripped atom | An atom minus all its electrons; a nucleus. (05 Mar 2000) |
| displacements per atom | (dpa) This is a measure of the amount of radiation damage in neutron-irradiated materials, for example, 10 dpa means each atom in the material has been displaced from its site within the structural lattice of the material an average of 10 times (due to interactions between the atoms and the energetic neutrons irradiating the material.) (09 Oct 1997) |
| quaternary carbon atom | An atom of carbon to which four other carbon atom's are attached. (05 Mar 2000) |
| ionised atom | <chemistry> An atom that possesses an electrostatic charge as a result of loss or gain of electrons; e.g., H+, Calcium, Cl-, O2-. (05 Mar 2000) |
| tagged atom | A radioactive atom, or a stable but rare one, which by its presence in a molecule helps localization or measurement of that molecule. Synonym: tagged atom. (05 Mar 2000) |
| excited atom | An atom possessing more than normal energy as a result of input of energy. See: excited state. Synonym: excited atom. (05 Mar 2000) |
| labelled atom | A radioactive atom, or a stable but rare one, which by its presence in a molecule helps localization or measurement of that molecule. Synonym: tagged atom. (05 Mar 2000) |
| receptors, cytoplasmic and nuclear | Proteins in the cytoplasm or nucleus that specifically bind signalling molecules and trigger changes which influence the behaviour of cells. The major groups are the steroid hormone receptors, which usually are found in the cytoplasm, and the thyroid hormone receptors, which usually are found in the nucleus. Receptors, unlike enzymes, generally do not catalyze chemical changes in their ligands. (12 Dec 1998) |
