Successfully manufacturing radiation warning equipment

Vietnamese scientists have successfully manufactured monitoring equipment and warned early levels of environmental radiation.

Thanks to this device, abnormal radiation developments will be quickly detected and transmitted immediately to the operating center to promptly respond to radiation incidents.

Scientists at the Center for Acceleration and Electronics, Nuclear Science and Technology Institute (Vietnam Atomic Energy Institute) have researched and successfully built the kind of early observation and warning devices. Environmental radiation, high efficiency, the cost is only 1/3 compared to the same product of foreign countries.

Step by step mastering radiation warning technology

'Radiation early warning and monitoring equipment acts as a radiation monitoring station but is highly sensitive by using a blinking detector and being able to quickly transmit information to the management center. management, administration ' . Dr. Tran Ngoc Toan, member of the research team said.

According to scientists, in the past, a number of domestic nuclear facilities have gained certain achievements in the field of manufacturing devices such as analytical systems, industrial and medical control systems. , geology, environment, dose measurement and radiation warning but in fact are very limited in terms of quantity and quality such as sensitivity, low stability, mechanical structure is not compact, beautiful design. Most equipment must be imported from abroad with a high price, easily damaged due to hot and humid weather conditions. However, each failure must depend on foreign experts, the warranty repair is therefore very time consuming and expensive.

Facing the above situation, scientists of the Center for Accelerator and Electronics, Nuclear Science and Technology Institute (Vietnam Atomic Energy Institute) have studied and manufactured monitoring equipment for early warning. radiation.

Compared to previous dosing and warning devices manufactured by domestic facilities, this device has many outstanding advantages such as high sensitivity with an extended range of active doses by using many different probes. for each dose zone. Tracking results are stored in the device's RAM. The device also has the function of identifying some simple isotopes and connecting the internet. The network multiplexing can create a monitoring network in a large area (within a country).

Dr. Dang Quang Thieu, director of the Center for Acceleration and Electronics, chairman of the project, said this success opened up the ability to master technology, solve the problem of localization of radiation monitoring and warning equipment. , convenient for the management, use, maintenance and maintenance of equipment.

Effective but commercialized?

Early radiation monitoring and warning equipment is quite popular in many countries around the world, especially countries with nuclear reactors. Vietnam currently has more than 20 nuclear medicine facilities, hundreds of radiology facilities and many facilities using radiation sources and other nuclear technology applications. All of these radiation facilities require dosimeters and radiation warnings.

Testing of radiation monitoring and early warning equipment at the Institute of Nuclear Science and Technology gave quite satisfactory results, the largest error at the position near the environmental font was below 7%. This quality standard is nearly the same as the world-famous FUJI-type control equipment.

The device may be located in the national monitoring network or safety warning stations around nuclear power plants, reactors, nuclear fuel processing facilities; assess radiation levels indoors as well as outdoors or put on specialized vehicles for inspection and rescue.

The effect is already there, but according to the research group, this is a specific device to serve the state management of atomic energy and radiation safety, nuclear safety, not ordinary electronic equipment. Massive service for the poor people. Therefore, 'If the state does not order production, the equipment will be very difficult to become a commercial product' - Dr. Thieu said.
