Overview
The RC4000 Conveyor Radiation Detection System constantly
monitors your material handling conveyors for radioactive
materials.
The RC4000 Conveyor Radiation Detection System consists of
two main components - the RCD conveyor radiation detectors
and RC4000 Control Console. RCD radiation detectors are mounted
on the infeed conveyor to the shredder and downstream conveyor
after the shredder. The RCD detectors are connected to the
RC4000 console via a low voltage signal communication cable.
The signal cable utilizes double-shielded, multiple twisted-pair
conductors that carry low voltage DC power and logic levels
that are virtually immune from electrical noise.
The RCD detectors measure the ambient radiation levels on
a continuous, uninterrupted basis. These measured levels
are converted into digital signals that are transmitted to
the RC4000 computer and then analyzed by the high-speed microprocessor
system. The software analysis controls the sampling of the
incoming measured signal for the purpose of establishing
a continuous running reference of the ambient background
radiation level.
Each RCD detection unit will be scanned and alarm levels
calculated independent of the other detection units in the
system. During normal operation, the RCD units utilize indicators
on the top level display that allow the operator to view
the operational status of each detector. During normal operation
the indicators will be green. In the event of an alarm condition
on any one or all of the RCD units, the indicator will turn
red with an accompanying alarm level indicating the intensity
of the radiation level. When the alarm occurs, all of the
detailed information regarding the alarm condition will be
stored in memory and can be retrieved from Menu option Data.
The alarm information will include the detector number, alarm
condition, alarm data collected, date, time and specific
sample status (e.g. highest reading taken). The system never
stops analyzing the measured radiation levels from the RCD
detectors regardless of the system operating condition.
The system also provides digital logic output that can be
used to operate external audio and visual system status and
alarms and to control conveyor motors. Each conveyor can
be controlled independently depending upon the location of
the suspect material. For example, if the suspect material
is located on the infeed conveyor, only the infeed conveyor
will be stopped leaving
the downstream conveyor running to remove the cleared material.
If the suspect material is in the downstream conveyor (too
well shielded for the infeed detector to detect until shredded)
then all the conveyors stop to prevent contamination of previously
shredded and cleared material.
The RC4000 has many additional features other than alarm
data retrieval such as; time/date, display of RCD measured
radiation levels, system configuration adjustments, system
testing without a radioactive source, and remote factory
access by modem or internet. Many of the system features
are protected by a security code entry. |
