Although ionising radiation can be used to destroy corina virus under experimental conditiins but its use in covvid-19 trestment may not be appropriate as iit may damage other healthy cells in tje body. Ionising radiation can be used for development of vaccine for covide -19.

Yes is possible to produce a vaccine through ionizing radiation because ionizing radiation is also rays that can destroy the activities of coroana virus and secondly coroano virus cannot survived on temperature that is between 25_30 degree ,it can only survived above 30 degree that is ionizing radiation or heat temperature which can destroy the virus

Yes, I would say, absolutely. Jenner found a weaker form of the smallpox virus that he used for a vaccination. Pasteur did his first own "attenuation" of the rabies virus using a chemical process involving phenol. Theoretically radiation could be used for producing an "attenuated" virus for a vaccine. Then the various vaccine products would have to be tested in culture, animals and then clinically. I would think that today, there are much more precise, strategic, and efficient ways, in the lab with RNA manipulation, to achieve the results of rather crude irradiation.
