James:
To further the excellent article Protection from Radioactive Fallout by Tennessean:
The author cites “The Effects of Nuclear Weapons, Samuel Glasstone and Philip J. Dolan, 670 pages, November 2006”. A reprint version of this book is available, but is more
than $50 at Amazon in paperback.
As this book is in the public domain, I have made an on-line version of the 1977 Third Edition available at my site for many years.
The index points to PDFs for the individual chapters which may be printed or downloaded for offline storage.
Accompanying it is a web application which implements the circular slide rule which accompanied the 1962 edition, plus instructions for making your own physical slide rule.
