Radioactive early warning device

For the first time, researchers from the Institute of Nuclear Science and Technology successfully fabricated radioactive early warning devices with high sensitivity, quickly detected radioactivity and timely response.

This device acts as a high-sensitivity but radiation sensitive monitoring station by using a flashing detector (probe) and is able to quickly transmit information to the management and administration center. .

According to scientists, many nuclear facilities have achieved much success in radioactive warnings but all have been imported from abroad with high prices and not suitable to the conditions of Vietnam. Therefore, scientists from the Institute of Nuclear Science and Technology have created the device for the first time in Vietnam and given certain results.

According to Dr. Dang Quang Thieu, the project leader, with radioactive early warning and monitoring equipment, unusual changes or changes in radiation will quickly detect and transmit to the control center and people. to promptly respond.

The team said that when radioactivity appeared in Ninh Thuan, the device could transfer data quickly to Hanoi via the internet so that managers could make timely decisions. Or if radiation from China, the group's device can record radioactive concentrations, while relying on the wind direction to predict the direction of radiation.

"Compared to the previous warning devices, the device manufactured by the research team has many advantages. The device has the function of identifying some simple isotopes and grafting the internet, creating a monitoring network. newspaper " , Dr. Thieu said.

"The radioactive early warning device was also tested and showed that the error and quality indicators were similar to the German control equipment or foreign technology introduced , " added Dr Thieu.

The device will be located in the national monitoring network or safety warning stations around nuclear power plants, reactors, nuclear fuel processing facilities.

The above topic has been highly appreciated by the Ministry of Science and Technology and has good practical application in the condition that countries around the world are developing nuclear technology and Vietnam is preparing to build Ninh nuclear power plant. Thuan.
