Read MoreRadiation Carcinogenesis
As acceptance of radiation therapy for skin cancer grows, questions arise as to the long-term risks therapeutic radiation poses. This is an area extensively measured and studied by radiation physicists and medical dosimetrists. However, from practical point of view, most of empirical data comes form epidemiological population studies. The most dramatic of these being atomic…
