Allen's new book, Actions for Survival - Saving Lives in the Immediate Hours After Release of Radioactive or Other Toxic Agents also comes with, upon request, a free RADSticker radiation monitor (dosimeter) which will be provided attached to the inside of the back cover.  As discussed in Chapter 8, the dosimeter has many advantages, including the facts that it can be pasted easily to a small card wallet, is easily read, and measures radiation dose received only when the dose approaches levels requiring actions to produce harm.

You may order the book online through MJR Publications.
