- Abstract
The Space Radiobiological Exposure Facility (SREF) is a general scientific payload onboard the China Space Station (CSS) for scientific research in the fields of space radiation protection, space radiation biology, biotechnology, and the origin of life. The facility can load biological samples such as small animals, plant seeds, microorganisms, and organic molecules to carry out long-term exposure experiments in space. During experiments, temperatures of the environment can be controlled in a specified range, small animals can be cultivated with the use of microfluidic chips and observed real-time with a microscopy, and the space environments such as ionizing radiation and solar ultraviolet are measured with the linear energy transfer (LET) detector, neutron detectors, and solar ultraviolet (UV) detector. The SREF has been operating since June 2023 and three exposure experiment missions have been successfully conducted due to October 2024. The exposure time was three months, 9 months and 6 months respectively. The results of the operations, monitoring and measurements of the SREF aboard the CSS are discussed.
