Description

Colibri is a comprehensive health physics instrument that performs numerous radioprotection daily duties.

The large color touch screen reports real-time, error-free measurements for up to eight CSP-CANBERRA Smart Probes (seven via Bluetooth and one via CSP standard cable) while always displaying dose-rate at worker location.

Colibri provides both fast reacting semi-log bargraph and averaged digital reading for each measurement window. The main window displays either the internal detector dose-rate or the external probe read-out and the secondary window shows the cumulated dose or the Colibri dose-rate when one or multiple external probes are connected.

It is always ready to go with no-memory-effect rechargeable batteries and accompanies the worker in the field with minimum constraint. It can be worn on the belt with a permanent smooth clip, or held comfortably in the hand using the finger strap and secure wrist strap.

The Colibri’s speaker emits alarm sounds as well as other audible signals. In the event of a radiation hazard, regardless of working conditions, an alarm will sound along with a flashing LED and vibrator. The standard available off the shelf Bluetooth headset will better support source and contamination location in noisy environments.

Colibri TTC integrates a GM detector with CANBERRA superior Time- To-Count technique that covers never achieved dose rate range from background up to 10 Sv/h reducing the risk of saturation in unexpected high dose rate situations. Dose-rate is automatically stored every five seconds in a date stamped internal file allowing for post analysis.

Quality assurance and traceability is naturally embedded in Colibri operations for each logged data and answer typical questions like:

Colibri is compatible with all CANBERRA Smart Probes (CSP). The probes extend the capabilities of the instrument to a range of general surveying applications. With CSP design, key components of hardware circuitry (high voltage, amplifier, discriminator, etc.) are located directly inside of the probe housing rather than in the host survey instrument. Also, the intelligence associated with controlling those components is located in the probe – that is, control and storage of key parameters, settings, calibrations, probe ID, alarm settings, etc. Thus the probe is a fully-integrated subsystem acquiring and transmitting the measurement to the instrument, which is used for display.

With high voltage and digitization of the data occurring in the probe rather than the instrument, measurement accuracy is no longer dependent on cable quality as with older analog systems. Also, the probes can be plugged in “hot” without powering down the instrument – the instrument immediately recognizes the probe and automatically switches measurement to the mode required for that specific probe.

Calibrations and QA measurements can be performed directly with the probe, without even using the instrument, by connecting the probe to a computer with the CANBERRA calibration software (CSPS™). This allows Colibris’ to remain deployed in the field while various probes are being calibrated.

The Colibri can be connected to external probes by a cable. It can also connect to the CSP probes with wireless technology (Bluetooth) via CSP-COM modules, eliminating the need for a cable. This eases contamination surveys as the user is not dependent on cable length and cable coil-ups.

Timer Scaler

Colibri incorporates a scaler timer mode that allows user to select an integration time from 1 s to 255 s and improves MDA. It displays the number of counts for the selected period of time and the average value in selected unit.

Source Finder Mode

The source finder mode has been designed to monitor and display on an easy-to-understand graphic showing the radiation trend vs. time, in any of the pre-selected units. The graphic updates can be chosen within three different dwell times: Fast = 250 ms, Medium = 500 ms or Slow = 1 s.

This mode is useful in decommissioning applications with contamination probes, when the audio control is not enough and when a more precise control is required.

Background Subtraction

Colibri includes a background subtraction mode. It allows acquisition of a background for a selected duration and subtracts it from next measurements to display and store net results. Colibri allows for the setting of a validity period after which the device will query the user to perform a background update. This mode is useful when performing contamination measurement in a constant background area, thus obtaining measurements reflecting real contamination of a monitored object.

Data-Logging and Mapping applications

Colibri is the perfect instrument for mapping applications. It can save a large number of measurements associated with location data, such as GPS coordinates, barcode, RFID tag or simply an incremental index. GPS is a Colibri internal option while Barcode or RFID readers connect via Bluetooth link.

Each logged data is encapsulated with QA information about external probes and /or internal detector calibration traceability.

The automatic data-logging function stores up to 60 000 records of 1 to 255 seconds acquisition with time interval of 0 to 200 000 seconds. It is a powerful mapping tool when GPS coordinates are available.

Colibri manages three date stamped CSV files (MS-EXCEL compatible) for each day of operation:

• Automatic and transparent storage of dose-rate every five seconds.
• Manually triggered data-logging with internal detector and/or external probes.
• Automatic data-logging.

This selection facilitates data retrieval because the user only needs to identify the day of interest.

Colibri improves ALARA

Colibri will always warn you of any radiation hazard. When used without an external probe, Colibri displays both the dose rate and the cumulative dose taken since the Colibri has been powered on. When an external probe is connected, it displays both the external probe measurement and the internal dose rate, allowing the user to be aware of the dose rate level when he is focused on the contamination survey.

Colibri features a loud audible alarm, visible LED and vibrator, triggered by alarm set-point for dose-rate, cumulative dose and external probes.

Colibri can connect to remote probes with the wireless Bluetooth link. Probes can transmit measurement data from the hot zone to the user, eliminating the need for the user to enter the hot zone to control the area. It can also be used to assess the radiation risk before entering into a hazardous area. This decreases the total dose exposure for the worker.

A Customizable Instrument

Colibri connects to a PC using a standard web browser for data transfer and instrument setup. Connection can be wired with the USB Colibri cable (part of standard delivery) or wireless with internal Bluetooth link if the user computer is Bluetooth capable.

Colibri can be set to any level between fully open and highly restricted for a dedicated worker or a group of users.

Colibri includes user and profile management to adapt the instrument to worker capabilities depending on his primary task. The log-in function can be enabled to bring an additional level of traceability since each measurement stored is then linked to a specific user name or group of users.

Colibri data and parameters are password protected.

Multiple Probe Connection

Colibri can connect to eight CSP probes (one via standard cable and seven via CSP-COM Bluetooth) and display all probe measurements simultaneously. The user can decide to focus on one specific probe manually or automatically if a probe turns an alarm off. The latest alarming probe is always displayed in main window.
