CHAPTER 1: BEFORE YOU BEGIN
1.1 Introduction
Polimaster Gamma Personal Radiation Detector PM1401MA (hereinafter referred to as
“the instrument” or “РМ1401MA”) is a personal radiation detector with highly sensitive CsI(Tl)
scintillation crystal which provides fast response and localization of gamma radioactive
sources.
When ON, the instrument continuously monitors the environment for radiation and
alerts the user with visual, audio and/or vibrating alarms if radiation source is detected or any
of preset radiation thresholds are exceeded. All operations history is stored in the device’s
permanent memory, protecting the data even when the battery is removed. The stored data
can also be transferred from the PM1401MA to a personal computer via its IR interface.
The instrument can be used in both indoor and outdoor environments and is intended
for everyday and/or emergency use by firefighters, military, police, and other first responding
communities.
