Preface
What’s New
Software Changes
Version 2.2.0 of the radon monitor software interface includes the following new
features:
•Report Cover Page: A Create Cover Page checkbox has been added to the
print preferences. If this checkbox is selected, the report cover page will
include a selectable image and general information about the test site and
inspection company. For more information, see “Changing the Report (Print)
Preferences” on page 44.
•Report Shows if Mitigation System Installed: A Mitigation System
Installed checkbox has been added to the Print Preferences. If this checkbox
is selected, the printed report will indicate that a Radon mitigation system
was installed at the test site. The user can also display on the report whether
the mitigation system was working or not working at the time the test was
conducted. For additional information, see “Changing the Report (Print) Pref-
erences” on page 44.
•Report Header Image: A Select Header Image option has been added to the
Print Preferences. If a header image is selected, it will appear at the top of
the first page of the report (not the cover page or other report pages). The
header can be aligned to the left, center, or right of the page. For more infor-
mation, see “Changing the Report (Print) Preferences” on page 44.
•Report Images (Last Page and Cover): A Pictures tab has been added to the
main software screen. Up to six images can be selected for printing on the
last page of the report. If the cover page option is enabled, one of the images
can also be printed on the cover page of the report. For details about adding
images, see “Main Screen - Pictures Tab” on page 37.
•Report - Signature on First Page: If an image of the inspector’s signature is
selected, the user can also choose the Print Signature on First Page check-
box in the Print Preferences to print the signature on both the first and last
pages of the report. For details about this option, see “Changing the Report
(Print) Preferences” on page 44.
•Report - Terminology Changes: In the report, the term “Elapsed Time” has
been changed to “Exposure Time” per EPA protocols. Also, % has been
added to the humidity label on the Model 1029 report page.
•Report - Page Numbers: Page numbers are now printed at the bottom of
each report page (except the cover page).
•Report - Time Display: The time is now displayed correctly in the printed
report (Hrs:mins).

vi
•Report - Signature: The signature image is now correctly positioned in the
printed report.
•Report - Print Radon Information: The main software screen displays infor-
mation about Radon Risk and how to understand time-sensitive testing
protocols. If desired, these information panels can be included in the printed
report. For details, see “Changing the Report (Print) Preferences” on page 44.
•Other Terminology Changes: The software screens and printed report now
display “Inspection Company” instead of “Inspector Info”.
•License Field Enhanced: The ‘License Number’ field now supports up to 100
characters. Multiple license numbers can be separated with any character,
such as comma, dash, colon, etc. For details, see “Changing Monitor Set-
tings” on page 41.
•Chart Enhancements: The chart that is displayed on-screen and in the report
has been improved for easier reading.
• The chart title now includes the monitor model number and serial
number.
• The horizontal screen now displays the date in single-day increments
instead of the a date and time stamp to reduce clutter.
• The Action Level line (red, horizontal) is always displayed, even if the
maximum radiation count is less than the action level.
• The Action Level line can be hidden by deselecting a checkbox in the
chart legend panel.
• The chart now displays the overall overage (or EPA overall average)
above the legend panel as well as the words ‘Motion Detected’ if a
motion event is recorded in the chart. Additionally, if a Model 1029 is
connected, the chart will also display the Average Temperature, Average
Pressure, and Average Humidity above the legend panel.
• If a Model 1028 is connected, the chart will no longer show blank entries
for temperature, pressure or humidity. These values are only displayed
when a Model 1029 monitor is connected.
For details about these changes, see “Main Screen - Chart Tab” on page 35.
•Checklist: The software now provides a checklist that the inspector can use
to verify that best practice actions were completed prior to staring the test.
For details, see “Main Screen - Checklist Tab” on page 38.
•Retrieve Data from Text File: Data that is saved to a text file can be opened
directly from the software. When a text file is opened, the file data populates
the screen options and chart data. For details, see “Data to/from Text File” on
page 40.
•Site Address: The software now includes entries for both Billing Address
and Site Address. If the Billing Address is the same as the Site Address, the
information can be copied so the user does not have to retype the address.
The Site Address and Billing Address are both displayed in the printed report.
For details, see “Main Screen - Inspection Tab” on page 32.

vii
•Documents on CD: The CD that is distributed with the Radon Monitor now
includes three documents that the inspector can provide to the homeowner.
The main screen in the software lists the documents for easy reference. For
details, see “Main Screen - Inspection Tab” on page 32.
•Clear Screen button: The Clear Screen button in the software interface
clears all data that has been retrieved from the monitor and removes the pre-
vious data from the screen. This provides a a visual cue for the user that all
existing data has been cleared and new data can be retrieved from the mon-
itor. For additional information, see “Inspection Tab Details” on page 33.
•USB Drivers Installed Automatically: The software installation routine now
installs the USB drivers automatically. A separate driver installation proce-
dure is no longer required. See “Installing Software” on page 29.

Introduction
Description
The Continuous Radon Monitor (Figure 1) is a patented detection device to
measure the concentration of radon gas. The unit is designed for professional
inspectors to use in homes and buildings.
Figure 1. Continuous Radon Monitors, Models 1028 and 1029
This guide covers both the Models 1028 and 1029. Model 1029 has greater
sensitivity plus temperature, pressure, and humidity sensors.
The radon monitor requires a standard 9V battery. It can be operated on an
alkaline battery alone for up to 100 hours or use an AC adaptor and use the battery
as a backup power source. A lithium-ion battery will provide about 300 hours of
operation.
A 16-character display shows instructions and radon readings. By pushing the
buttons below the display, the user can enter data, set parameters, and print
reports on an optional portable printer.
The radon monitor connects to a computer via a USB or serial cable. The
Windows software on the provided CD can be used to download measurements,
set parameters, and print reports on a printer connected to your computer. See
“Computer Operation” on page 29.
The Continuous radon monitor has been EPA verified and radon proficiency pro-
grams approved.

2
Typical Application
In a typical test, place the radon monitor in a building or structure to be
monitored, connect power, and leave it unattended for the required test period.
Ambient room air, laden with radon, diffuses into the radon monitor’s detection
chambers. Gaps between the base and the cover allow air to freely pass into the
radon monitor. Radon decay by-products emit alpha particles which are detected
by the photo diodes and then counted. During a test, the number of counts
produced by the alpha particles is stored in memory and converted into radon
concentration (pCi/l) using the stored calibration factor.
At the end of the test period, the results can be viewed on the radon monitor
display, on the computer screen, or in a printed report.
After viewing or printing the report data, clear the memory. A new test cannot be
started until memory is cleared. The instrument is completely reusable and
requires no supplies except line power and/or a 9V battery.
The radon monitor can be moved from the test site, and the report printed later.
