Radiological Dispersal Device (RDD) [Dirty Bomb]
First Responder's Guide
he First 12 Hours
A radiological dispersal device (RDD) or dirty bomb is a mix of explosives, such as dynamite, with radioactive powder or pellets.  When the dynamite or other explosives are set off, the blast carries radioactive material into the surrounding area. The activities that take place in the first 12 hours are critical.   

The RDD Handbook is now available online at no charge and on CD for $10, in addition to the nicely bound book, which is available for $30.  While supplies last!

RDD Handbook

RDD Pocket Guide

CRCPD has created a Handbook for Responding to a Radiological Dispersal Device First Responder's Guide—The First 12 Hours as a training and reference tool for first responders with various degrees of radiological experience, providing guidance in a number of areas.  This includes a flow chart of actions when responding to an RDD, Rules of Thumb guidance, determination of various radiation zones, use of radiation instrumentation, and decontamination guidelines. 

There are also multiple forms that can be tailored for specific needs.  The RDD Handbook also includes lists of state, local and federal radiation control contacts that can provide assistance. 

This handbook will be useful for training, exercise and response activities.  Many of the concepts introduced in the handbook can be applied to a variety of radiation incidents, and do not apply exclusively to dirty bombs. 

It is intended for use by first responders (Fire, EMS, Police, HAZMAT), although the first receivers (EMS/EMT, medical staff at hospitals or other clinical settings) may also elect to use it as a guide when preparing to respond to an RDD event. To the greatest extent possible, the information has been kept simple and concise, and references for additional information have been provided.

The RDD Handbook, CRCPD Publication #06-6, consists of the bound document, a CD containing forms and handouts, and one RDD Pocket Guide.  Price: $30, including shipping within the United States. 

This pocket guide (3" x 5"), a companion to the RDD Handbook, was developed by radiation experts so all first responders are working with the same guidelines.  Designed to be taken into the field as a quick reference, this very durable, waterproof, and alcohol-safe pocket guide provides both general and specific information for use during the first 12 hours after the detonation of an explosive radiological dispersal device (RDD), also called a dirty bomb.

Included in the guide are a What To Do flow chart, suggested incident zones for impacted areas and suggested activities for each of these zones during the first 12 hours, turn-back exposure rates and dose guidelines, and what will provide a shield from each type of radiation, as well as some Rules of Thumb guidance.


The RDD First Responder's Pocket Guide, CRCPD Publication #06-RDD-PG, is available for $1.50 each, including shipping within the United States. 

When ordering quantities of 5,000 or more, your information can be printed on the Contacts panel of the guides at no additional charge, saving you time and money by eliminating the need for labels.

Here's what the RDD Pocket Guide looks like.  The 16.25" x5" document has five panels (four accordion folds), making it a 3"x5" guide that easily fits into your pocket.
