A firm called Company RadioMedic Ltd., developed at the Nuclear Physics Institute of the ASCR in 2009, deals with the development, manufacturing and distribution of radiopharmaceutical preparations. It has developed a radiopharmaceutical with an active substance that selectively binds to hypoxic cells. These tumor cells are more sensitive to radiotherapy and chemotherapy in the presence of oxygen in tissue and consequently the number of the hypoxic cells is a limiting factor for a therapy effect.
