A fully automated on-line radiation water monitor.

Wilma utilises a novel approach to streamline the time consuming process of sample collection and preparation traditionally required for detecting radiation (specifically alpha and beta contamination) in water via liquid scintillation counting.

Wilma is ideal for simplifying a range of applications which require routine sampling, including:

• Ground water radiation contamination monitoring.
• Monitoring tritium levels in cooling water.
• Quasi real-time radiation monitoring of drinking water.

Fully integrated radiation water monitor

The simple, self-contained unit combines fluid handling systems for sample collection, preparation, and disposal, with radiation detection and analysis of contamination, all within a rugged and compact housing – measuring just 480 x 400 mm and designed to operate in demanding environments.

Totally autonomous radiation measurements

The self-contained water radiation monitor is able to operate independently, for as long as it has the necessary reagents. Wilma was designed to minimise waste production and reduce the consumables required. With a well-characterised response and stable background, this design allows a unit to continue running without supervision for in excess of 30 days.

Simple to use instrument

Wilma includes a touchscreen PC running user-friendly software, which allows easy configuration and monitoring of sampling and measurement cycles. Default measurement cycles can be provided to bring the instrument on-line soon after installation.

Completely customisable online monitor

Designed, developed and built by the LabLogic Group, Wilma can be fully customised to suit any application. The system can integrate additional sensors and measurement systems, handle complex sampling and preparation routines, and integrate with external monitoring and alarm networks. Two of the configurations currently available are:

1. Ground Water Radiation Monitor

The Wilma Ground Water Monitoring System combines the proven Wilma fluid handling and LSC modules with additional pumping and sensing capabilities to manage the extraction and characterisation of ground water samples at the source. The system can be configured for remote measurements and transmit data via a secure wireless network. Ideal for campaign-based measurements, the system is mounted inside a rugged IP65-rated enclosure for all-weather protection.

2. Tritium in Air Monitoring System

The Wilma Tritium in Air Monitoring System utilises the configurable Wilma fluid handling and LSC detector to automate the operation of a tritium bubbler. The customised software includes cycles to sample water in the bottles, as well as emptying, washing and refilling them as part of the standard operating procedure. This application allows long-term, remote monitoring of tritium in air levels down to less than 10 Bq/m3, ideal for monitoring in isolated locations or areas where access is difficult.
