Ball and Moore's Essential Physics for Radiographers--------------------------------------------------Since its first edition in 1980, Essential Physics for Radiographershas earned an international reputation as a clear and straightforwardintroduction to the physics of radiography. Now in its fourth edition,this book remains a core textbook for student radiographers. The authorshave retained the pragmatic approach of earlier editions and continueto target the book particularly at those students who find physicsa difficult subject to grasp. The fourth edition builds on the majorrevisions introduced in the third edition. The content has been updatedto reflect recent advances in imaging technology. The chapter on RadiationSafety has been completely rewritten in the light of the latest changesin relevant legislation, and a re-examination of the physical principlesunderpinning magnetic resonance imaging forms the basis of a new chapter.Worked examples and calculations again feature strongly, and the innovativeand popular Maths Help File, guides readers gently through the mathematicalsteps and concepts involved. The reference citations have been updatedand now include Internet sources.--------------------------------------------------Author Biography: John Ball is former Principal at the South West WalesSchool of Radiography, Swansea.
