INTRODUCTION
While in an area which has been exposed to nuclear radiation, there is a
need to perform radiological monitoring and surveys.
You will learn the
monitoring and survey types and techniques, reporting dose rate, and
correlation and transmission factors.
PART A - AREA MONITORING
Radiological monitoring is the act of detecting the presence of radiation
and measuring it with RADIAC instruments. Monitoring provides warning of a
hazard that otherwise might go undetected. For example, monitoring alerts
the command to the arrival of fallout or alerts units on the move when they
contact a contaminated area.
The RADIAC instrument used in monitoring
radiologically contaminated areas is the survey meter. The AN/VDR-2 RADIAC
Set is used to locate and measure radioactivity in the form of Gamma Rays
and Beta particles. It is used to measure fallout contamination after the
nuclear burst, normally H+48 hours or longer.
