RADON Change ventilation system / radon checks According to CDT Minnesota Department of Health (2007)‚ Radon is a radioactive gas - that means it continuously decays and releases radiation. It is produced from minerals in soil‚ such as uranium and radium. Although radon is present throughout the environment‚ when high levels are present indoors people are exposed to more of its radiation and their risk of cancer increases. Such a situation can be discovered easily and corrected. POLLUTION Public

INTRODUCTION 2007 ISO radioactivity danger logo Radioactive wastes are wastes that contain radioactive material. Radioactive wastes are usually by-products of nuclear power generation and other applications of nuclear fission or nuclear technology‚ such as research and medicine. Radioactive waste is hazardous to most forms of life and the environment‚ and is regulated by government agencies in order to protect human health and the environment. Radioactivity diminishes over time‚ so waste is

Chapter 1 From X-Rays to Ion Beams: A Short History of Radiation Therapy James M. Slater Abstract Radiation therapy (RT) developed in several eras. Patients’ needs for more effective treatment guided the efforts. The development of ion beam therapy (IBT) can be seen as a corollary in this continuous endeavor to optimize disease control while minimizing normal-tissue damage. It could not have materialized‚ however‚ without the curiosity‚ ingenuity‚ and perseverance of researchers‚ engineers
