Now the global epidemic prevention work is still not lax. As for our country, it is necessary to eliminate the cold chain new coronavirus. After all, there has been an epidemic before.

Recently,China Tongfu and the Institute of Microbiology of Chinese Academy of sciences have determined the experimental scheme of inactivation of new coronavirus by using small irradiator. China Tongfu is responsible for designing and providing special irradiation equipment, and the Institute of Microbiology of Chinese Academy of Sciences is responsible for the detection and evaluation of virus before and after irradiation. The experimental scheme has been approved and implemented.

The main research goal of this project is to carry out the research on the irradiation disinfection of new coronavirus, establish the irradiation disinfection process of new coronavirus, and provide the basis for the irradiation disinfection of new coronavirus in imported cold chain food. The research results are of great significance for the elimination of new coronavirus in imported cold chain food and the prevention of new coronavirus in important international competitions.

According to reports, CNNC's key technology project team has carried out the research on the simulation process of inactivation of new coronavirus in cold chain food. In the past three months, a series of irradiation inactivation experiments have been carried out using two kinds of simulation new coronavirus, and a large number of experimental data have been obtained. The simulation experiment shows that the lower radiation absorbed dose can achieve the inactivation effect, and has no impact on food safety.

At present, the research team has initially determined the dose range of irradiation inactivation of new coronavirus, but it is still a huge challenge to verify the experimental inactivation dose by using new coronavirus, and there is no similar literature report and research work in the world for reference.

The medical and health field is one of the most important application fields of irradiation technology, especially the disinfection and sterilization of medical supplies. According to data released by the International Atomic Energy Agency,At present, about 12 million cubic meters of medical devices are sterilized by irradiation technology every year, and more than 40% of all disposable medical devices produced in the world are sterilized by irradiation. The common disposable infusion sets, needles, surgical instruments, etc. in hospitals are all sterilized by irradiation.
