발암물질: 두 판 사이의 차이

종합환경대책보상 및 부담법(CERCLA, Comprehensive Environmental Response, Compensation and Liability Act)은 방사성핵종들이 발암 물질이라고 정의하였다. 방사선의 발암성은 방사선의 종류, 노출 또는 투과되는 정도에 따라 달라진다. 예를들어 [[알파입자]]는 낮은 투과성을 보이며 체외에 존재할 경우 위험하지 않다. 그러나 흡입하거나 섭취하였을 경우에는 위험하다.

 

 

낮은 농도의 전리 방사선은 회복할 수 없는 DNA 손상을 주며 노화, 암을 발생시킨다.<ref>Acharya, PVN; The Effect of Ionizing Radiation on the Formation of Age-Correlated Oligo Deoxyribo Nucleo Phospheryl Peptides in Mammalian Cells; 10th International Congress of Gerontology, Jerusalem.
