BEIJING, Oct. 25 (Xinhua) -- The following is a summary of published science and technology news of China.
RADIATION DOSE DETECTION CHIP
China's self-developed X-ray and gamma-ray (X/γ) radiation dose detection chip has successfully commenced mass production.
The chip, developed by the China National Nuclear Corporation, 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.
ALLERGIC DISEASES
Chinese researchers have found that morphological changes of an immune receptor play a key role in allergic reactions, a discovery that could provide new insights useful for the development of allergy medications.
Researchers from the Shenzhen Medical Academy of Research and Translation and Westlake University have revealed the mechanisms behind allergic reactions by analyzing protein structures.
SCIENTIFIC PAYLOADS
The scientific payloads for space breeding and other sci-tech experiments carried by China's first reusable and returnable satellite, Shijian-19, were delivered to Chinese and foreign users on Thursday.
At the payloads handover ceremony held by the China National Space Administration (CNSA) in Beijing on Thursday, the CNSA and the China Aerospace Science and Technology Corporation signed payload delivery certificates with domestic and international users, including those from Thailand and Pakistan. ■
