microprocessor and LCD technology and features a rugged ionization chamber with a
mylar window and protective steel mesh. An integral beta shield serves as an
equilibrium thickness for photon measurements. The ergonomic handle, features a
large diameter cushioned grip and is designed to reduce fatigue associated with
extended use. The case is constructed of lightweight, high strength materials and is
sealed against moisture. The user must specify R or Sv when ordering.

Radiation Safety
Model 451EXL
• Complete remote radiation
information management for Model
451P and 451B Ion Chamber Survey
Meters
• Color-coded data provides quick
identification for radiation levels and
alarm acknowledgment status
Introduction
Features
The 451 Assistant for Excel is an Excel Add-in, a program that adds optional commands and
features to Microsoft® Excel. The 451 Assistant provides remote control for many of the 451
functions, real-time data logging with user defined alarm parameters and a real time virtual
instrument display. The 451 Assistant automatically loads with Excel once it is installed.
• Real time data logging in protected Excel
worksheet
The 451 Assistant data logging function automatically records real time measured data in an
active Excel worksheet. Each measurement in the data log is automatically placed in the active
worksheet cell, then the active cell moves down to the next row of cells where it will place the
next set of measured data. Each recorded measurement is time and date stamped. The
451 Assistant provides user configurable audible and visual alarms for the real time logged
data. The picture and data shows radiation levels above the preset alarm in red, the blue data
represents the radiation level below the alarm that has not been acknowledged. The black data
shows when the alarm was acknowledged. See Control Options for more details.
The 451 Assistant for Excel allows the user to configure the 451’s internal data logging and
alarm settings. It may also be used to download the 451’s internal data log and saves it in an
Excel worksheet where it can be easily graphed for quick trend analysis.
The 451 Assistant provides automatic timed integrated dose measurement over a user defined
integration period or user controlled integrated dose measurement. After the integration timer
has expired or the user has stopped integration, the 451 Assistant retrieves the integrated dose
from the 451 and inserts the integrated dose in the active worksheet cell and the average dose
rate is placed in the next cell to the right.
Applications
This Model 451EXL information management software program is ideal for the facility
Radiation Safety Officer or anyone responsible for maintaining a permanent record of spills
and accidents for adherence to state and NRC requirements. The remote control of the 451
series of Ion Chambers may be accessed by any computer on your facility network providing
remote information management.

Specifications
Controls
The 451 Assistant menu and toolbar provide an interface for the user
to remotely control the 451, configure the 451, download the 451’s
internal data log and start / stop real time data logging and integrated
dose measurements
Download Log The 451 is capable of internally logging data at a
user defined interval from 1 to 255 seconds with a total capacity of up
to 2700 data points. This feature allows the user to download the
451’s internal data log into the active Excel worksheet
Options Allows the user to change many properties of the
451 Assistant for Excel and several of the 451s’ properties. The user
may configure the various visual and audio alarm features of the
451 Assistant for Excel for each data point that is logged. The
451 Assistant can be configured to use 2 or 4 alarm states. The four
alarm states are acknowledged normal (below alarm level),
unacknowledged normal, acknowledged alarm and unacknowledged
alarm. The user may also select the communication port used by the
451 (default is COM1). The 451’s internal data logging parameters
and alarm settings may also be changed from the Options menu
Connect / Disconnect Connects or disconnects the 451 to the
computer’s communication port
Start / Stop Starts and stops computer data logging. When data
logging is started, logged data is placed in the active Excel worksheet
and the worksheet is protected to provide data security
Logging Properties Allows the user specify computer data logging
parameters. The data logging sample interval (2 seconds to 999 hours),
total data logging period (2 seconds to 49 days) and computer data
log alarms may be specified through this menu. These parameters are
independent of the 451’s internal data logging functions
Integrate… Allows the user to select timed integrated dose
measurement or user controlled integrated dose measurement. The
user may also specify the integration period for timed integration from
1 minute to 999 hours. When timed integrate mode is selected, the
451 Assistant for Excel stops the integrated dose measurement after
the specified integration period has expired
When timed integrate mode is not selected, the user controls the
integration period and the integration time is displayed in real time.
The integrated dose and average dose rate are recorded in the active
Excel worksheet when integration is complete

Introduction
RS
Radiation Safety
• Cutie pie style with tripod for longterm monitoring
The Model 470A Panoramic Survey
Meter is designed to be used in and
around medical facilities for many low
level radiation monitoring activities. The
Model 470A has a very low energy
response (down to 10 keV). That makes
it ideal for diagnostic x-ray suites,
including mammography. Since this
meter can measure up to 1000 R/h, it is
also ideal for radiotherapy facilities. The
Cutie Pie style of this meter allows it to
sit on three legs for long-term monitoring
or to be used as a hand-held survey meter
with the convenient grip handle.
• Low level radiation monitoring for
diagnostic x-ray and radiotherapy
suites
• Available in SI units
Features
• Measures all energies over 2 pi solid
angle
• Collimator provided for directional
identification
• Twelve overlapping rate ranges from
3 mR/h to 1000 R/h full scale
Applications
The Model 470A is popular in health physics instrumentation. Solid state IC
technology is utilized to simplify circuitry, reduce weight and increase reliability.
Designed to provide the user with convenience as well as measurement accuracy, the
Model 470A has numerous applications in the health physics field. Certainly its
outstanding features will suggest many other areas beside diagnostic x-ray and
radiotherapy suites where it can be used to great advantage.

Technical Operations Model 773. A copy of your
license must accompany the order.
This sturdy, easy-to-use device permits the safe, accurate calibration of instruments
used for surveying gamma radiation. It enables users of dosage-measuring equipment
to perform routine checks at will or as necessary to meet the regulations of the NRC
and Agreement States.
The heavy-duty lead container holds 165 mCi of 137Cs, encapsulated at one end of a
control rod. Since 137Cs has a long half-life (30 years), there is no need to calculate a
correction factor for at least 1 to 2 years after the instrument is shipped.
Applications
The source can be kept in either of two positions: stored or exposed. In the fullyshielded “stored” position, radiation at the container’s surface is less than
200 mR/hr; at 1 meter away it is less than 10 mR/hr. In the “exposed” position, the
source faces a 36° (horizontal) x 20° (vertical) port at the shield’s side. The radiation
field can be varied by means of three built-in attenuators (transmission factors 0.25,
0.10 and 0.10). These permit calibration of three meter scales, each at 20% and 80%
of full scale, using only one source-to-meter distance measurement. The source is
moved from “stored” to “exposed” merely by raising the control rod. For safety, the
137
Cs source cannot be removed from its shield, except by the manufacturer.
A built-in tape measure helps determine the distance from the 137Cs source to the
instrument being calibrated. A padlock (not included) can be used to prevent
unauthorized use of the equipment. A convenient carrying handle is included.
