China begins mass production of homegrown X/γ radiation dose detection chip

China's self-developed X-ray and gamma-ray (X/γ) radiation dose detection chip has successfully commenced mass production, according to the Science and Technology Daily, Report informs via Xinhua.

The chip, developed by the China National Nuclear Corporation (CNNC), offers a dose rate measurement range for X/γ rays from 100 nSv/h to 10 mSv/h. It can detect energies between 50 keV and 2 MeV.

With a compact size of just 15 mm by 15 mm by 3 mm, it can operate within a temperature range of minus 20 to 50 degrees Celsius. Additionally, it boasts ultra-low power consumption of only 1 mW.

Users can easily perform straightforward secondary development based on the chip's data manual, enabling its use in radiation dose monitoring across nuclear-related workplaces, personnel and environmental scenarios, according to the CNNC.

It also features a standardized interface design, allowing it to function as a universal radiation sensor, which can be quickly integrated into various smart devices such as smartphones, smart helmets and drones.
