LESSON 1
COMPUTE TRANSMISSION FACTORS FOR SHELTERS AND VEHICLES
USED FOR SHIELDING RADIOLOGICAL FALLOUT
Critical Task: 031-506-2047
OVERVIEW
LESSON DESCRIPTION:
In this lesson you will learn how to compute transmission factors for shelters and vehicles used for
shielding from fallout. You will learn how shielding affects the amount of radiation absorbed by the
body and how to determine transmission factors.
TERMINAL LEARNING OBJECTIVE:
Compute transmission factors for shelters and vehicles used for shielding
ACTION:
radiological fallout.
Given information and illustrations of shelters and vehicles used for shielding
CONDITION:
radiological fallout, the procedures for taking readings inside and outside the
shelters and vehicles, and the methods for computing the transmission factors for
shelters and vehicles used for shielding radiological fallout.
Demonstrate competency of the task skills and knowledge by responding to the
STANDARD:
multiple-choice examination covering the computation of transmission factors for
shelters and vehicles used for shielding radiological fallout.

INTRODUCTION
Under the threat of or actual conditions of nuclear warfare, units in the field must continually evaluate
the impact that enemy use of nuclear weapons has on the conduct of operations and be prepared to
initiate an alternate course of action to reduce the disruption caused by a nuclear attack. Nuclear fallout
may be employed to blanket areas of poorly defined targets, create obstacles, canalize movement,
disrupt conduct of operations, and force the relocation of support facilities. Fallout can have a
