Todays lecture Friday 16.January

Dear students, I understand it was bad weather this morning, sins only one student showed up. I left the handouts for this weeks topic "interactions between radiation and matter" in the bookcase for you. Chapter 7 in Attix and Chapter 2 in Webb's are required reading this week. Next Wednesday is devoted to dosimetry, and Friday to exercises on Basic photon interaction, image quality, and Exam set 2006 Midt Oppg. 1&2. Please come, since we need four students to arrange the cource. best regards HILDE
