Diagnostic radionuclides and radiation-producing devises (x-ray machines) are mainly used to investigate and diagnose potential health issues. Despite the benefits that radiation provides to health care, radiation exposure may pose some health risk to both patient and worker. An

Radiation Therapy for Prostate Cancer: A Patient Guide
urology.ucsf.eduRadiation therapy uses ionizing radiation in the form of photons or protons to kill cancer cells by damaging their DNA. Cancer cells with damaged DNA cannot divide or multiply and will eventually die. The overarching goal of radiation therapy is to deliver a therapeutic dose of ionizing radiation to the tumor
Introduction to Radiation
nuclearsafety.gc.caRadiation is energy in the form of waves of particles. There are two forms of radiation – non-ionizing and ionizing – which will be discussed in sections 3.1 and 3.2, respectively. 3.1 Non-ionizing radiation . Non-ionizing radiation has less energy than ionizing radiation; it does not possess enough energy to . )
