Introduction
The Ludlum Model
720 Spectroscopic Area Radiation Monitor is a high powered system that not
only logs routine ambient radiation levels and annunciates any alarms, but
additionally identifies the isotope(s) that are present whenever an alarm is
manifested. This intelligent system is designed to be connected to an
Ethernet network that can accommodate up to 50 Ludlum radiation area
monitors. Upon an alarm, the Model 720 will automatically capture a
spectrum and analyze it against a library of up to 100 isotopes and then
convey the results over the network where it can be viewed by
Ludlum’s Webpage
and Service Software using any standard browser program. All data
are logged to a MS SQL database and if desired to a csv type file. Up to 10
browsers (more with purchase of other versions of MS SQL) can then access
all the data including a system overview, incident reports and timeline
graphs. Each incident will also collect and store the spectrum along with
the analysis identifying the isotopes that were present. If optional
network cameras are connected to the system, an image of the offending item
is additionally captured and sent to the database where it is stored along
with the other incident data.
Another
key feature of this system is its ability to automatically send out
Emails to responsible parties by event type so immediate action can be
taken. Up to 10 emails can be broadcast in an intelligent fashion so
that only the supervisors or other responsible persons available on that
shift are notified. The system additionally supports separation between
those responsible for direct response to a radiation alarm and others
who maintain the equipment if an equipment failure alarm is posted.
Providing real-time alarm annunciation at numerous monitoring stations
as well as directly to responders with all the facts pertaining to the
location, gross gamma levels, isotopic mix, and visual images will
enable a more accurate and timely response to any incident that occurs.
Ludlum’s Model 720 Spectroscopic Area Radiation Monitor in combination
with its
Webpage and
Service Network Software package offers an affordable
solution that combines all the latest technologies into one seamless
package that enables response in a more efficient and effective manner.
