The American Association of Physicists in Medicine (AAPM) has created this website for use by educators, students, and members of the general public. The site is divided into twenty different thematic areas containing links that profile all aspects of medical physics, including "Data & Standards", "Publications & Publishers", and "Students and Junior Physicists". The "Nuclear Medicine & PET Resources" area is a good place to start, and there are several links to internal resources that the AAPM has created, which provide an introduction to nuclear medicine. Moving on, the "Physics Data & Standards" area has several dozen links to material on x-rays, ionizing radiation standards, and reference data sheets. The site is rounded out by the "Publications" area, which offers direct links to some of the key journals in the field, such as "Medical Physics" and the "Journal of Applied Clinical Medical Physics".
