Radiographic Photography and Imaging Processes

The imaging aspects of radiography have undergone con­ many sources and was in general freely given when requested siderable change in the last few years and as a teacher of and this is gratefully acknowledged. In particular I would radiography for many years I have often noticed the lack of a like to express my sincere thanks for help and information to comprehensive reference book for students. This book is an Mr J. Day of DuPont (UK) Ltd. particularly for the infor­ attempt to correct that situation and I hope this text will be mation and illustrations in the chapter on automated film of value not only to student radiographers but also prac­ handling; Mr D. Harper and Mr R. Black of Kodak Ltd. ; tising radiographers as well. Fujimex Ltd. ; CEA of Sweden; 3M (UK) Ltd. ; Wardray Much of the information is based on personal experiment Products Ltd. ; D. A. Pitman Ltd. ; Agfa-Gevaert; PSR Ltd. and the knowledge gained of students' difficulties in studying for their help with information on silver recovery, and this subject. I have attempted to gather together in one book Radiatron Ltd. for their help with safelighting. All were most all the information required to understand the fundamentals helpful in my many requests for information. of the subject both for examination and for practice. Some To Mrs A. Dalton and Mrs P.
