| 설명 | 빛의 전자자기파나 혹은 입자파(α, β, γ선)를 말하는데, 어떤 근원물질에서 생겨 방출된다. 이온쌍을 생성하는 고에너지 방사선(X-선과 감마선)을 말한다. 방사선하면, 주로 전리방사선을 의미한다. 이런 방사선을 이용하여, 가장 기본적인 방사선학적 검사를 할 수 있으며, 이외 치료에도 이용하고 있다. 각 방사선의 종류에 따라 조금씩 인체에 미치는 영향이 다르며, 이를 이용하여 각기 다르게 진단 및 치료에 이용한다. |

| 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 | radiation therapy | 한글 | 방사선요법 |
|---|---|---|---|
| 설명 | X선, γ선의 전자방사선이나 전자선, 양자선, 중성자선 등의 입자방사선을 이용해, 주로 악성 종양 치료를 목적으로 하는 치료법이다. 암세포가 주위의 정상세포보다도 방사선 감수성이 높은 점을 이용하여, 정상세포의 손상을 가능한 한 최소로 억제하면서 암세포를 파괴한다. 사용되는 방사선에는 밀봉소선원에서 나오는 γ선, 직선가속기에서 얻어지는 고에너지 X선과 전자선, 텔레코발트장치에 의한 60Co의 γ선과, 베타트론에 의한 전자선, 사이크로트론에서 얻어지는 양자선, 중성자선 등이 있다. |

| 영문 | radiation therapy | 한글 | 방사선치료 |
|---|---|---|---|
| 설명 | 방사선의 살균효과나 세포를 죽이는 효과를 치료에 이용하는 방법으로, 좁은 의미로 암의 방사선치료를 의미한다. 암에 대한 방사선치료는 암세포를 죽이는데 효과가 큰 베타선을 주로 사용한다. 하지만, 이런 방사선치료는 정상세포에도 큰 영향을 끼쳐 이에 따른 기능의 장애를 가져올 수 있다. 따라서 방사선치료에 있어서는 단지 그 암세포에 대한 작용뿐만 아니라, 정상세포에 대한 작용도 고려하여 시행한다. |
