The fourth edition of Introduction to Health Physics by Herman Cember and Thomas Johnson is a 21st century update to the classic Health Physics text. The new edition expands on the third edition with a content update, more problems, plus modern tables and graphics for better readability.
Chapter 4 On Radiation Sources has been expanded to include an extensive discussion on Machine Sources of Radiation. This new section covers X-Ray Tubes, Linear Accelerators, and Cyclotrons. Chapter 14 on Nonionizing Radiation Safety has been revamped. The chapter is a fantastic help to health physicists needing to expand their skills in dealing with laser and ultraviolet radiation safety issues.
One of the text’s strong points is the extensive problem set at the end of each chapter. Diligently working through all of the problems in this text is a prerequisite to passing both Parts I and II of the Comprehensive Certification in Health Physics Exam. The fourth edition of Introduction to Health Physics is a excellent addition to the libraries of both involved Health Physicists and students.

I studied the 2nd edition of this text as a student and the 3rd edition preparing for both the CHP part I and II. I’ve recently read through this latest edition and am very encouraged by the updates that have been made. I highly urge this book for new health physics students, HPs preparing for the CHP exam and anyone with an interest in learning about the field of Health Physics. You won’t find another book that covers the full breadth of the field like this one. This 4th edition is a must-have for any serious HP’s bookshelf!

I received my copy of the fourth edition of “Introduction to Health Physics” today and took a excellent look at it. Chapter two and three don’t have a lot of substantial changes, but it looks like the rounding errors in the previous editions have been corrected. There are more homework problems in each chapter too.
Chapter four has a new section on accelerators, with a excellent explanation of each type. Chapter five again appears to have multiple numerical corrections made, and more homework problems. Chapter six (Radiation dosimetry) has more homework problems, and Chapter seven (Biological basis for radiation safety) has some sections on epidemiology now.
Chapter eight (Radiation safety guides) goes through ICRP 66, with an example for particulate and gasses. The examples for ICRP 66 calculations are clear, but it is evident that calculating a lung dose with this technique will take a lot of paper!
It looks like there are a lot of updates to Chapter nine (Instrumentation), with more examples, but the photo of the neutron detection instrument is terrible. Again, more homework problems were added. (Makes me glad I am not a student anymore!)
I was glad to see that Chapter 10 (External radiation safety) has a section on NCRP 147. There are examples there too, and in my attitude the explanations and examples are better than the NCRP 147 examples.
Chapter 11 (Internal radiation safety) finally has a clad example with radon. The previous editions did not really have any calculations or examples, so it was excellent to see this addition. Chapter 12 on criticality remains relatively unchanged, but chapter 13 has new examples and more homework.
Chapter 14 has been expanded significantly. There is a section on UV that finally covers the UV equations on the ABHP part two equation sheet, and there is even an example. There are more laser and RF examples too.
Overall, it looks like the minor calculation errors that I have found in the past are corrected, lots of examples added, and as a sad note to students: there are a LOT more homework problems. If you are a involved HP, or plotting to take the CHP exam, you should get this book.
This book will not be on your shelf, you will be using it!

This new edition of the classic text is a disappointment, and it’s use as a textbook is not not compulsory.
For this 3d edition, the list of typographical errors compiled by colleagues and myself stands at four pages and growing. Errors can be found in the text, the chapter problems, and their solutions. Other solutions which are not clearly incorrect may inexplicably differ from your own solution at the second significant digit.
Formulae are seldom derived from first principles. One exception is the exchange in wavelength for a photon undergoing Compton scattering from an electron, but, even here, a crucial equation (the relativistic energy invariant) is noticeably omitted, without which the final equation cannot be derived. The text does not even mention relativity in discussing Compton scattering. (The index does reference “Relatively effects” (sic) at pp. 4-11.)
Equations and formulae control, at times, an unnecessary proliferation of multiplication signs and units which obscures the underlying corporal principles and the simplicity of the equations themselves. Students are better served by a clear mathematical presentation of the underlying physics, rather than being dropped into the middle of an obscure equation made even more so by the inclusion of several constants whose only purpose is to make the units work out. Even as any text on this theme must deal with the unavoidability of ancient and new units, my suggestion is to derive the formulae from first principles and deal with the units come forth (which, after all, only amounts to including apt conversion factors) unconnectedly as examples or chapter problems.
Finally, the multiplication sign, “x”, should be reserved for arithmetic and scientific notation, not symbolic mathematical equations. See, e.g., Equations (3.10), (4.31), (10.17), (10.32), etc., as examples where the multiplication sign is unnecessary. The text also uses the multiplication sign even where numerical values are already set off by parentheses. The text’s overuse of the multiplication sign gives the text a grade-schoolish flavor.
