The principal possibility of the composite particles production by the radiation-chemical method with acceptable productivity was shown. The composite particles were produced in the nanoscale range (50 and 80 nm) from aluminum oxide partially coated with silver. The coating percentage was from 2–3% for smaller particles to 16–40% for larger composite. The stability of the suspension before irradiation using different stabilizers was studied, and the reason for the change in the color of the suspensions after ultrasound treatment was determined. The biological activity of the nanopowder which showed a high level of antibacterial activity was investigated.
