1. Introduction
The UltraRadiac-Plu s is a du r abl e, portable,
personal radiation monitor. Once set up, it is
preconfigured to detect certain types of
radiation, and then alert you using an audible
and/or vibrating alarm and a visual data
display. It can log (save a reco r d of) radiation
data for further evaluation by your
Administrator.
READ
THIS
If you don’t read anything else
in this manual, read the
chapters
Controls and
Indicators on pag e 5 and Basic
Operations on page 9
. These
cover the basics of using the
UltraRadiac-
Plus Personal
Radiation Monitor.
Note: Operational pro cedures are the
responsibility of the UltraRadiacPlus’s users. Instructions provided in
this manual are “how to’s”, not
procedural recommendations.
1
Chapter 1 Introduction
Your UltraRadiac-Plu s can measure and
display both the instantaneous radiation dose
rate (Rate), t he amount of radiation bein g
measured at t his moment, and the total
accumulated radiation dose receiv ed (Dose)
since the dose memory was last cleared.
The Alarms
The UltraRadiac-Plus’s presettable alarms for
both instantaneous R ate and cumul ative Dose
can alert you to hazardous conditions. When
an enabl ed alarm’s threshold is exceeded, a
visual indicator will begin flashing and,
optionally, an LED will blink and/or an
audible alarm will sound. All units also
include a vibrator alar m th at can be
independently set.
The Radiation Units
Depending on the model, your UltraRadiacPlus is factory-set to display the Rate and the
Dose in one of these units of radiation
measurement:
• R (roentgen) – a measure of radiation
exposure.
• Sv (sievert) – a measure of absor bed
dose equival ent.
2
Most illustrations in this manual show the
radiation units as µR (microroentgens, one
millionth of a roentgen). The units are defined
in the appendix Default Alarm Settings on
page 65.
Equipment Check
If your organization’s procedures require
periodic equipment checks, refer to the
chapter Operational Verification Tests on
page 16.
Setting Up the Unit
The UltraRadiac-Plu s has five modes: R ate,
Dose, Source Finder, Sleep, and Data
Logging. The chapter Setting Up the Unit on
page 28, describ es them and tells you how to
set and en able the Rate alar ms and the Dos e
alarms.
Maintenance Procedures
The chapter Maintenance on page 48, lists the
UltraRadiac-Plus's pr eventive maintenance
checks and describes how to install, charge, or
replace th e batteries. Th e U ltraRadiac-Plus
uses four AAA batteries and can accept either
alkaline or rechargeable Ni MH .

Chapter 1 Introduction
Note: The battery recharging d evi ce should
only be used with NiMH batteries.
Connecting the charger with Alkaline
batteries may result in severe damage
to the batteries or the device.

Display Test Sequence
The Battery Life Indicator
The UltraRadiac-Plus has two battery life
indicat ors. See The Batteries on page 49 for
instruct ions on chang i ng the ba t teries .
• If a blinking 8 is displayed, the unit has
stopped functioning. Replace the
batteries before the unit’s next use.
• If a blinking BAT is seen in the top-left
corner of the display, the unit’s batteries
have 10 hours or less of useful life.
Replace the batteries as soon as
possible.
• If the display is blank, the batteries are
dead. Replace the batter ies before th e
