|---|---|---|---|
| 설명 | 보라색보다 더욱 파장이 짧은 400nm 이하의 볼 수 없는 광선이며 다음의 3종으로 나눈다. ① 200~290nm(UVC): 저압램프에서 조사되는 것으로 DNA를 저해하며 피부에 조사되면 홍반이 생긴다. 대기중의 O3나 H2O에서 흡수된다. ② 290~320nm(UVB): 피부가 햇볕에 타서 검게 되며 지나치면 수포나 피부암을 일으킬 위험이 있다. ③ 320~400nm(UVA): 지표면에 많으며 무해하다. 다량이 폭로되면 피부에 색소침착을 일으킨다. |

|---|---|---|---|
| 설명 | 290~320nm의 자외선. 일광화상과 그을림을 가장 효과적으로 유발한다. 백인에서 자외선 과다는 피부암을 유발할 수 있다. |

| 영문 | ultraviolet C | 한글 | 짧은파장자외선 |
|---|---|---|---|
| 설명 | 200~290nm의 자외선 방사. UVC라고도 한다. 일광의 UVC는 지구 표면에 도달하지 않는다. 멸균/수은아크등은 일광화상과 각막염을 유발할 수 있다. |

| vacuum | Origin: L, fr. Vacuus empty. See Vacuous. 1. <physics> A space entirely devoid of matter (called also, by way of distinction, absolute vacuum); hence, in a more general sense, a space, as the interior of a closed vessel, which has been exhausted to a high or the highest degree by an air pump or other artificial means; as, water boils at a reduced temperature in a vacuum. 2. The condition of rarefaction, or reduction of pressure below that of the atmosphere, in a vessel, as the condenser of a steam engine, which is nearly exhausted of air or steam, etc.; as, a vacuum of 26 inches of mercury, or 13 pounds per square inch. Vacuum brake, a kind of continuous brake operated by exhausting the air from some appliance under each car, and so causing the pressure of the atmosphere to apply the brakes. <medicine> Vacuum pan, a glass tube provided with platinum electrodes and exhausted, for the passage of the electrical discharge; a Geissler tube. Vacuum valve, a safety valve opening inward to admit air to a vessel in which the pressure is less than that of the atmosphere, in order to prevent collapse. Torricellian vacuum. See Torricellian.
