The National STEM Centre in the United Kingdom has been working on assembling useful resources across the various science, technology, engineering, and math disciplines for a number of years. One of their most successful projects has been their online database of resources, which draws on high-quality teaching materials from different universities, organizations, and institutions around the world. This particular section of this database includes resources on teaching medical physics. Users can search the collection by publication year or age group, and sign up for a free account to save the resources for later use. The materials include full textbooks on medical physics, teachers' presentations, lecture notes on medical physics and radioactivity, and a learning exercise on the medical uses of ultrasound. There are dozens of other resources, and the site will warrant several return visits.
