Develop and radiation monitoring

29 October 1998

EG&G develops MiniMCA

Tennessee based EG&G Ortec has launched a 4k-channel MiniMCA-166 for nuclear safeguards and other spectroscopy applications. The equipment has been developed at the Rossendorf Research Centre in Germany under IAEA guidance.

Eurisys Measures develops individual and transport monitors

Eurisys Mesures has developed the C 2000 monitor designed for Alpha/Beta surface contamination of personnel. It meets with all IEC 1098 standards and, comprising 25 two-chamber 800 cm2 gas flow detectors, corresponding to a total of 50 20x20 cm detector cells.

The company has also recently launched its Syren monitors, designed for radiological control of pedestrians, vehicles, trucks and rail cars. The monitors can be interconnected in a modular system and are designed to monitor any movement of nuclear materials or sources of gamma radiation at the exits from nuclear sites, arsenals, hospitals or at the entrances to scrap yards, incinerators or dumps.

Hörmann monitoring at Kola

German company Hörmann GmbH is to develop the second phase of the Automated Off-site Radiation Monitoring System (AORMS) for the Kola nuclear power plant. The environmental conditions and remote location of the Russian Federation plant, on the Kola peninsula, 200 km north of the Arctic Circle, pose particular challenges for Hörmann.

The major components of the system Hörmann is delivering include five automatic monitoring stations to record meteorological parameters on the ground, a Sodar/RAS system to monitor the atmosphere and one mobile radiological monitoring laboratory.

The permanent monitoring of the meteorological situation will allow operators to forecast radiation situations using mathematical models. The equipment will complement that which is already in place following the first phase of AORMS development.

ROV develops radiation surveillance system

Vermont based ROV Technologies has developed a personal contamination monitor alarm system designed to view and record any contamination events. The system is designed to use only one camera in a given field of view, covering multiple monitors. Each monitor is wired to an alarm transmitter which waits for a signal from a monitor indicating which monitor has alarmed. It is capable of responding to 64 separate alarm inputs.

WSRC designs new air monitor

Westinghouse Savannah River Company has developed an on line air monitor designed to reduce the number of false alarms compared to traditional glass filters.

Comprising air inlet and outlet lines, a radiation detector, a sample box, a sintered stainless steel filter disk and a vacuum pump, the monitors are used in radioactive environments downstream from air filters designed to prevent releases of radioactivity.

Siemens upgrades its monitoring systems

iemens has launched a new version of its EPD dosemeter, boasting better performance and design than the original EPD. It measures ICRU dose quantities and is accurate in a range from 1µSv to 16Sv. The new EPD uses standard IrDA infrared communications to talk to a computer or access control terminal from up to one metre distance.

The company has also developed TeleTrak wireless monitors. A product that can be used individually or integrated within a ‘modular’ configuration. TeleTrak can act as a backbone for data management for workers on highdose/dose rate jobs, groups of area monitors, other detectors such as air samplers and ‘smart’ portable monitors.

Siemens’ Decontamination Simulator is designed to train people to clean and decontaminate hazardous particulate materials or solutions.

In conjunction with Hunting Engineering and the UK Department of the Environment, Siemens Environmental Systems has redeveloped the UK’s radioactive incident monitoring network (RIMNET). RIMNET Phase 2 involves a network of 92 monitors around the country, providing continuous gamma radiation dose rate measurements, as well as a powerful central database facility which can assimilate information from a large number of sources.
