Abstract: In general, the patent herein is a radioactive chemical which attaches to the virus and releases radiation which kills the virus. Specifically, the chemical is an alpha-ketoamide designed to attach to the virus. However, instead of 2 bromine atoms, Iodine-131 is at the location of where the bromine atoms would have been. Iodine-131 is a radioactive element which releases ionizing radiation. The virus with which this radioactive chemical is designed for is the COVID-19 coronavirus, although the patent is for any virus. Since, modifications can be made in chemical structure and radioactive chemical species, the patent is for any and all chemicals which contain any type of radioactive element to kill or disrupt any type of virus.
