| 영문 | radioactivity | 한글 | 방사능, 방사성 |
|---|---|---|---|
| 설명 | 전자자기방사선을 방출하여 핵을 붕괴시키는 현상으로 원소기호 83번 이상인 모든 원소의 자연적 특성이며, 또한 다른 모든 원소들도 방사능을 가지도록 유도하는 것이 가능하다. 이런 성질을 이용하여, 여러 가지 치료 및 진단에 쓰인다. |

| 영문 | radiography | 한글 | 방사선촬영(술) |
|---|---|---|---|
| 설명 | X-선이나 감마선에 특별하게 민감한 필름을 노출시킴으로써 신체의 내부 구조물을 필름에 영상으로 얻어내는 방법을 이르는 말이다. |

| 영문 | radioimmunoassay(=RIA) | 한글 | 방사면역측정법 |
|---|---|---|---|
| 설명 | 항원 혹은 항체의 존재여부와 양을 알아보는 아주 민감한 방법으로, 항원을 정량할 때는 항체와 방사성물질로 표시된 항원을 표본에 넣은 후 항원만 존재하는 분획과 항원과 항체가 결합되어 있는 분획을 분리해 내어, 각각의 방사능을 측정하여 표본의 항원량을 알아낸다. 즉, 표본항원의 양은 항원만 존재하는 분획의 방사능과는 비례관계에 있고, 항원-항체 분획과는 반비례관계에 있으므로 이들의 관계로 표본의 항원의 양을 계산해 낼 수 있다. 이런 방법은 여러 가지 면에서 장점도 있으나 방사능에 폭로된다는 단점이 있어 요즘은 효소면역측정법을 많이 사용한다. |

| 영문 | radioisotope | 한글 | 방사성동위원소 |
|---|---|---|---|
| 설명 | 원소기호는 같으나 중성자수가 다른 것을 동위원소라 하며, 방사능을 가지는 동위원소를 방사성 동위원소라고 한다. 이들은 안정된 동위원소로 핵반응기, 사이클로트론을 사용하여 만들어 낼 수 있는데, 이들은 핵의학 스캔, 방사 면역측정, 암의 치료에 이용된다. 이것은 3가지의 방사선입자를 분비하는데 알파입자, 베타입자, 감마입자가 그것이다. 이중 감마입자는 투과성이 뛰어나 진단과 치료에 많이 이용된다. |

| 영문 | radiology | 한글 | 방사선과학 |
|---|---|---|---|
| 설명 | 방사선의학. 의료에 사용할 수 있는 각종 방사선을 이용하여 질병의 진단 및 치료와 그 질병의 병태생리 또는 생화학적 연구를 하는 학문. 이는 X선을 이용하는 분야와 방사성 동위원소를 이용하는 핵의학 분야로 분류된다. X선을 이용한 질병의 진단은 X선이 신체 내의 조직 또는 이물 등에 의해 흡수 또는 산란되는 차에 의한 X선의 강도변화를 필름 또는 형광물질에 투영시켜 그 투과양상에 따라 판정하는 것으로, 특수검사시는 조영제-형광판-TV-컴퓨터 또는 정전기 등을 이용하여 진단율을 높인다. |

| radial eminence of wrist | A rather large flat eminence on the radial side of the palmar aspect of the wrist, due to the tuberosity of scaphoid and the ridge on the trapezium. Synonym: eminentia carpi radialis. (05 Mar 2000) |
|---|---|
| radial flexor muscle of wrist | <anatomy, muscle> Origin, common flexor origin of the medial condyle of humerus; insertion, anterior surface of the base of the second and most often sending a slip to that of the third metacarpal bone; action, flexes and abducts wrist radialward; nerve supply, median; its tendon travels in its own canal roofed by a layer of the transverse carpal ligament. Synonym: musculus flexor carpi radialis, radial flexor muscle of wrist. (05 Mar 2000) |
| radial fossa of humerus | A shallow depression on the anterior aspect of the distal humerus, superior to the capitulum of the humerus and lateral to the coronoid fossa, in which the margin of the head of the radius rests when the elbow is in extreme flexion. Synonym: fossa radialis humeri. (05 Mar 2000) |
| radial growth phase | The early pattern of growth of cutaneous malignant melanoma, in which tumour cells spread laterally in the epidermis. (05 Mar 2000) |
| radial head | The name applied to a head of origin of a muscle arising from the radius. Nomina Anatomica no longer lists any muscles as having radial heads, although formerly a radial head was listed for the flexor digitorum superficialis muscle Synonym: caput radiale. (05 Mar 2000) |
| radial head subluxation | Subluxation of the radial head within the elbow joint is also referred to as nursemaid's elbow. This orthopaedic condition is seen commonly in toddlers who may be lifted up by outstretched arms. Instability of the radial head leads to subluxation. The child with nursemaid's usually has their arm in hanging in extension at their side and any attempted movement of the elbow joint is met with pain. (27 Sep 1997) |
| radial immunodiffusion | <technique> A quantitative variation of immunodiffusion in which the agar gel contains evenly distributed antigen (or antibody) and its counterpart from the test sample diffuses into the gel from a single well resulting in a circular precipitin line around the sample well. The diameter of the precipitin ring is proportional to the concentration of the antibody (or antigen) present in the test sample. By comparing the diameter of the test specimen precipitin ring to known standards, a relatively insensitive estimation of the concentration of specific antibody or antigen can be achieved. (01 Dec 1998) |
| radial index artery | <anatomy, artery> Origin, radial; distribution, radial side of index finger. Synonym: arteria radialis indicis, arteria volaris indicis radialis, radial index artery. (05 Mar 2000) |
| radial keratotomy | A keratotomywith radial incisions around a clear central zone. A form of refractive keratoplasty used in the treatment of myopia. (05 Mar 2000) |
| radial nerve | <anatomy, nerve> A major nerve of the upper extremity. In humans the fibres of the radial nerve originate in the lower cervical and upper thoracic spinal cord (usually c5 to t1), travel via the posterior cord of the brachial plexus, and supply motor innervation to extensor muscles of the arm and cutaneous sensory fibres to extensor regions of the arm and hand. (12 Dec 1998) |
| radial notch | The concavity on the lateral aspect of the coronoid process of the ulna that articulates with the head of the radius. Synonym: incisura radialis. (05 Mar 2000) |
| radial phenomenon | Dorsal flexion of the hand occurring involuntarily with palmar flexion of the fingers. (05 Mar 2000) |
| radial ponderomotive force stabilisation | <radiobiology> In magnetic mirror devices, use of rf waves in the neighborhood of the ion cyclotron frequency to stabilise interchange modes. The radial ponderomotive force produced by a radial gradient in the applied rf electric field opposes the destabilising centrifugal force resulting from bad magnetic field curvature. The net particle current is in the direction that would result from field lines with good curvature, eliminating the drive for the interchange instability. (09 Oct 1997) |
| radial pulse | The pulse as appreciated at the radial artery usually in the wrist. (05 Mar 2000) |
| radial recurrent artery | <anatomy, artery> Origin, radial; distribution, ascends around lateral side of elbow joint; anastomoses, radial collateral, interosseous recurrent. Synonym: arteria recurrens radialis, recurrent radial artery. (05 Mar 2000) |
