| 영문 | gamma ray | 한글 | 감마선 |
|---|---|---|---|
| 설명 | 감마-붕괴로 인해 원자핵 안으로부터 방사되는 전자방사선. 같은 전자방사선인 X선과는 원자핵 밖의 현상으로 인해 발생되는 점으로 구별한다. 질량, 전하를 가지고 있지 않기 때문에 물질과의 상호작용은 알파선이나 베타선과 비교하여 매우 적으며 투과성이 매우 크다. 물질과의 상호작용은 X선의 그것과 본질적으로 차이가 없으며 에너지에 따라 톰슨산란, 광전효과, 콤튼산란, 전자쌍 생성, 광핵반응 등이 일어난다. 의료에 이용되는 것은 방사선 치료에서 60Co에 의한 외조사 또는 192Ir, 226Ra, 198Au 등으로부터의 감마선이 사용되고 감마-카메라를 사용한 핵의학 검사에서는 99mTc 등으로부터의 감마선에 의한 신티그램이 진단에 이용되고 있다. |

| 영문 | beta ray | 한글 | 베타선 |
|---|---|---|---|
| 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. |

| 영문 | infrared ray | 한글 | 적외선 |
|---|---|---|---|
| 설명 | 파장이 가시광선보다 길며 극초단파보다 짧은 750μm~1mm의 전자파. 눈으로는 볼 수 없고 일반적으로 공기 가운데에서 산란되기 어려우며, 가시광선보다 투과력이 강하다. 사진 적외선-근적외선-원적외선 따위로 나눌 수 있는데, 단파장 부분에는 사진 작용-형광 작용-광전 작용이 있어, 적외선 사진이나 적외선 통신-물질 감정-의료 따위에 이용한다. 1800년에 허셀이 발견되었다. 적외선은 물질에 부딛치며 구성분자의 열운동을 일으켜서 열효과를 주게되므로 열선이라고도 불린다. 태양광선의 약 52%는 적외선이다. 700~800nm의 적외선은 인체피부를 투과해서 피하에까지 이른다. 과도의 적외선 조사는 피부에 온열성홍반을 일으키게 해서 화상을 일으킬 수 있다. |
