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

BEIJING -- 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 on Thursday.

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.
